Answers

Answer:

a) root77

b) 2 root77 / ~17.55 cm^2

Step-by-step explanation:

a) by using Pythagorean Theroem,

a^2 + b^2 = c^2

2^2 + b^2 = 9^2

4 + b^2 = 81

81 - 4 = b^2

77 = b^2

root77 = b

b) 1/2bh is the quation for area thus,

area = 1/2 ( 4 ) ( root77)

area = 2 root77

or area = ~17.55 cm^2

Answer:

h = [tex]\sqrt{77}[/tex]

A =[tex]2\sqrt{77}[/tex]

Step-by-step explanation:

Rules for solving this problem:

Isosceles triangle rules

∠C = ∠ABC = BA

Because of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that

(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²

Area of a triangle

A = 1/2 (Base x Height) = 1/2 * bh

Step 1 - Find the height

[tex]h =\sqrt{9^2 - ((1/2)AC)^2} = \sqrt{9^2 - ((1/2)~4)^2} = \sqrt{9^2 - 2^2} = \sqrt{81-4} = \sqrt {77}[/tex]

Step 2 - Find the area

[tex]A = \frac{1}{2}bh = (\frac{1}{2})(4)(\sqrt{77}) = 2 \sqrt{77}[/tex]

Triangle ABC with vertices A(9,13), B(12,11) and C(8,7) scale factor: K=2 center of dilation :(11,14)

Answers

The answer should be C

The final position of the triangle will be at  A"(7, 12), B"(1,-3) and C"(-3,-7)

Given the coordinate (x,y), if this coordinate is dilated by a factor of 2, the resulting coordinate will be (2x, 2y).

Given the coordinate of triangle ABC, A(9,13), B(12,11), and C(8,7), if these coordinates are dilated by a factor of 2, the resulting coordinates will be ats A'(18,26), B'(24,22) and C'(16,14)

If these coordinates are dilated along the centre (11, 14), the final position of the triangle will be at A''(18-11, 26-14), B"(12-11, 11-14) and C"(8-11, 7-14) which is  A"(7, 12), B"(1,-3) and C"(-3,-7)

What is an eqination of the line that passes through the point (-3, -7) and parallel to the line 3x-y=5
I need the y=mx+b

Answers

Answer:

y = 3x + 2

Step-by-step explanation:

First you need to change the way the equation is said into a easier form:

y = 3x - 5

Since the line is parallel, you can use the same slope of 3:

y = 3x + b

Now you plug in the coordinates into the equation and solve for b:

-7 = 3 ( -3) + b

-7 = - 9 + b

-7 + 9 = b

2 = b

Now plig this into the equation and you have the answer

y = 3x + 2

twice the circumference of
half the radius of

Answers

Options

The circle at the new location has _____________ the original circle.

- the same center as

- twice the circumference of

- half the radius of

- the same area as

Answer:

the same area as

Step-by-step explanation:

When a circle is translated and reflected, the center of the circle will change; however, its area, circumference, radius and diameter remain the same.

This is so because, translation and reflection only affect the positioning of the circle not the size.

Considering the above analysis, we can conclude that option d answers the question correctly.

Answer:

The equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Isaiah was given a gift card for a coffee shop. Each morning, Isaiah uses the card to buy one cup of coffee. The original amount of money on the gift card was $10 and each cup of coffee costs $2.

The equation will be written as below,

$10 - $2x = A.

A is the amount of money remaining on the card

x is cups of coffee.

Therefore, the equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.
