Find the area of isosceles triangle 13cm height 10 cm base

Answer:

y = 4x + 15

Step-by-step explanation:

Using 'y=mx+c' form,

Since m = 4,

y = 4x + c

Substituting (-5, -5) into the above equation:

-5 = -20 + c

c = 15

Hence,

y = 4x + 15

Answer:

y = (1/x)+2.05

Step-by-step explanation:

We are only given one point, so there are an infinite number of possible equations.  But forging ahead, we can come up with at least one equation of an inverse relationship containing the point (-20,2).

By inversely, the function will produce lower values of y as x increases, or vice versa.  A good first step is to say:

 y = 1/x

As the value of x increases, the value of y decreases.  Invere accomplished.

Simple, elegant, and inverse.  If it were a person, she'd be on the cover of People Magazine.

But we want any equation to include the point (-20,2).

Let's see if we can move y=1/x to include (-20,2)

y=(1/x) + b

2 = (1/(-20)) + b

2 = -(0.05) + b

b = 2.05

The equation y = (1/x)+2.05 is an inverse equation that includes point (-20,2).

See the attached graph.  Note that when x = 0, the expression (1/x) becomes (1/0).  Division by zero is not allowed (undefined).  Use caution if in the neighborhood.

The area of the triangular section is 12 square units and the area of the entire figure is 60 square units.

We know that the Area of triangle is defined as the product of its height to its base.

Area of triangle =  height × base

From the figure, we can see that Height is = 4 units and the base is = 6 units,

So, the area of the triangular section is = 1/2 × base × height,

⇒ (1/2) × 6 × 4

⇒ 12 square units

The entire figure consists of two figure , one is a rectangle and the other part is a triangle,

So, the area of the entire figure is = Area of rectangle + area of triangle

⇒ 4×12 + 12

⇒ 48 + 12

⇒ 60 square units

Therefore, the area of the entire figure is 60 square units.

Randy's claim is not correct Therefore, he cannot purchase 3.5 pounds of chicken salad for $23.50

To determine if Randy's claim is correct, we can use the given linear graph and points to find the equation of the line that represents the relationship between the amount of chicken salad purchased and the cost.

We can use the two points (1, 7.5) and (3, 22.5) to find the slope of the line:

slope = (change in y) / (change in x)

slope = (22.5 - 7.5) / (3 - 1)

slope = 15 / 2

slope = 7.5

Now we can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept, to find the equation of the line:

y = 7.5x + b

To find b, we can use one of the points on the line, such as (1, 7.5):

7.5 = 7.5(1) + b

b = 0

So the equation of the line is:

y = 7.5x

Now we can use this equation to check if Randy's claim is correct. If he can purchase 3.5 pounds of chicken salad for $23.50, we can plug in x = 3.5 and see if y = 23.5:

y = 7.5x

y = 7.5(3.5)

y = 26.25

Since y = 26.25 is not equal to $23.50

Therefore, Randy's claim is not correct

The given function of the cost represents exponential growth.

A form of growth known as exponential growth occurs when the rate of expansion is proportionate to the present value. This implies that the rate of growth increases as the present quantity increases. An exponential function, such as the one in this question (y = abx, where an is the starting value, b is the growth factor, and x is the number of time periods), may be used to describe exponential growth. In natural and social processes, such as population expansion, economic growth, and the spread of illnesses, exponential growth is frequently seen. Yet, there are always resource constraints and other factors that will ultimately reduce or stop the expansion, therefore exponential growth cannot last eternally.

The given function is y=100(1. 05)^x.

To find cost for certain year we substitute different value of x.

From the function we observe that as the value of x increases the function increases continuously.

Hence, the given function of the cost represents exponential growth.

Step-by-step explanation:

Use the triangle bisector theorem:

"The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle."

so 12 is to 16  as   x is to 20

12/ 16 = x/20

20 * 12/16 = x = 15 units

Answer:

x = 15

Step-by-step explanation:

the segment inside the triangle is an angle bisector and divides the side opposite the angle into segments that are proportional to the other two sides , that is

[tex]\frac{12}{16}[/tex] = [tex]\frac{x}{20}[/tex] ( cross- multiply )

The proposed maximum wait time should be 24.2 minutes so that 1% of the customers receive a free meal.

To answer the vice president's request, the proposed maximum wait time should be 24.2 minutes so that 1% of the customers receive a free meal. This can be seen in the graph below, which illustrates the normal distribution of customer wait times with a mean of 20 minutes and a standard deviation of 4 minutes. In this graph, the area of the curve between 0 and 24.2 minutes represents the customers who will receive a free meal, and the area to the right of 24.2 minutes represents the customers who will not receive a free meal.

The normal distribution is a common probability distribution which follows a symmetric, bell-shaped curve. It is often used to describe real-world phenomena such as customer wait times in restaurants, since it is an effective tool for modeling variation in large datasets. The normal distribution can be determined by two parameters: the mean and the standard deviation. The mean represents the average wait time, while the standard deviation describes how the wait times vary.

In this case, the normal distribution has a mean of 20 minutes and a standard deviation of 4 minutes. This means that the average wait time is 20 minutes and that the wait times may vary by up to 4 minutes. The area of the graph between 0 and 24.2 minutes can be seen as the customers who will receive a free meal, as these customers waited longer than the advertised maximum wait time. The area of the graph to the right of 24.2 minutes represents the customers who will not receive a free meal, as these customers did not wait longer than the advertised maximum wait time.

By proposing a maximum wait time of 24.2 minutes, the company will not be losing out on any profit. This is because only 1% of customers will be receiving a free meal, and the cost of this will be more than offset by the increased customer satisfaction due to faster service.

The total mass of the apples Alex picked is 25 2/5 kilograms.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants

To find the total mass of the apples Alex picked, we need to add the mass of the red apples and the mass of the green apples.

First, let's convert the mixed numbers to improper fractions to make the addition easier:

15 ⅘ = 15 + 8/10 = 15 + 4/5 = 75/5 + 4/5 = 79/5

9 ⅗ = 9 + 6/10 = 9 + 3/5 = 45/5 + 3/5 = 48/5

Now we can add the fractions:

79/5 + 48/5 = (79 + 48)/5 = 127/5

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case:

127/5 = 25 2/5

Therefore, the total mass of the apples Alex picked is 25 2/5 kilograms.

Answer:

  f(-3) = 6

Step-by-step explanation:

You want the value of f(-3) given a graph of f(x).

To find the value of f(-3), locate -3 on the x-axis. Follow the vertical grid line to where it intersects the graph of f(x). Follow the horizontal grid line from there to the axis marked f(x), and read the value on the vertical scale.

The attachment shows this process, and that the value of f(-3) is 6.

__

Additional comment

Unless there is information to the contrary, the usual assumption is that each grid line represents one unit. Positive is to the right of the vertical axis, and up from the horizontal axis. Then x=-3 is 3 grid lines left of the vertical axis.

The notation f(x) means the value of function f depends on the value x. The expression f(-3) is the function value when x=-3. Here, it is found by reading the graph. In other situations, it might be found from a table or by evaluating an algebraic expression.

Using the dimensional analysis, 9 tsp is equivalent to 3 tbsp.

A conversion factor is a numerical ratio that relates two units of measurement for the same quantity

To convert 9 tsp to tablespoons using dimensional analysis, we can use the conversion factor that 1 tablespoon is equal to 3 teaspoons. We can set up the following proportion

1 tablespoon / 3 teaspoons = x tablespoons / 9 teaspoons

where x is the number of tablespoons we want to find. To solve for x, we can cross-multiply and simplify:

1 tablespoon × 9 teaspoons = 3 teaspoons × x tablespoons

9 tablespoons = 3x

x = 9 tablespoons / 3

The simplest form of the ratio 2m : 8cm : 40mm is

50mm : 2mm : 1mm

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.

For we to simplify the ratio , we have to convert the unit to the least form. The least form of the unit is millimeter

2m = 2× 1000mm = 2000mm

8cm = 8 × 10 = 80mm

40mm = 40mm

therefore the ratio will be in form of

2000mm : 80mm ; 40mm
