Step-by-step explanation:

Answer: 1,200

Step-by-step explanation:

lets split it like this first

now lets start with the first one 15*20=300

now the second one 45*10=450

now the third one 35*10=350

now the last one 10*10 i think i caint see the one number=100

now add all them together= 1,200

hope this helped

Answer:

D

Step-by-step explanation:

The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.

For A, f(x) is reflected over the x-axis.

For B, f(x) is rotated about a point.

For C, f(x) reflected over the y-axis.

And for D, f(x) is reflected over the line y = x.

So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.

The answer is below

Step-by-step explanation:

Calvin school is 2.3 miles directly south of his house. After school, he takes a bus 1.8 miles west of his school to the sport complex.

a) What is the length of a straight line between calvins house and the sports complex? Round to the nearest tenth.

b) Calvin takes piano lessons at a community music school located 3.7 miles directly north of the sports complex. What is the length of a straight line between Calvin's house and the music school? Round to the nearest tenth.

Solution:

a) Calvin school, his house and the sport complex form a right angled triangle. The hypotenuse of the right angled triangle is the length of the line between Calvin's house and the sport complex. Let the length of the line between Calvin's house and the sport complex be x.

Using Pythagoras law for right angled triangle, we get that:

x² = 2.3² + 1.8²

x² = 8.53

x = √8.53

x = 2.9 miles to the nearest tenth

b) This forms a right angled triangle with the hypotenuse = length of a straight line between Calvin's house and the music school. one side of the triangle = 1.8 miles and the other side = 3.7 - 2.3 = 1.4 miles.

Let x = length of a straight line between Calvin's house and the music school. Hence:

x² = 1.8² + 1.4²

x² = 5.2

x = √5.2

x = 2.3 miles to the nearest tenth

this is a vertical

Step-by-step explanation:

Answer:

5 cm

Step-by-step explanation:

The distance a coiled spring stretches varies directly with the amount of weight hanging on the spring.

Distance = D

Weight = W

Hence:

D ∝ W

D = kW

Where k is constant of proportionality

Step 1

We solve for k

If a spring stretches 2 cm when a 30 gram weight is hung from it.

2 = 30k

k = 2/30

k = 1/15

Step 2

how far will it stretch when a 75 gram weight is hung from the spring?

D = kW

We are solving for D

k = 1/15

D = 1/15 × 75

D = 5 cm

The spring would stretch 5cm with a weight of 75 gram.

Answer:

-3

Step-by-step explanation:

:)

Answer:

We have the relation:

aₙ = 10 + 2*(n - 1)

And we want to write this in fuction form:

y = f(n)

first we have:

aₙ = y =  10 + 2*(n - 1)

We can rewrite this as:

y = 10 + 2*n - 2

y = 2*n + (10 - 2)

y = 2*n + 8

Now we want to find the y-intercept, this is the value of the function when the variable is equal to zero.

Then if we take n = 0, we get:

y = 2*0 + 8

y = 8

The y-intercept is 8.

Answer:

x=5

Step-by-step explanation:

Answer:

2(2x + 3)=4x + 3x - 9

4x+6=4x+3x+−9

4x+6=(4x+3x)+(−9)

4x+6=7x+−9

4x+6=7x−9

4x+6−7x=7x−9−7x

−3x+6=−9

−3x+6−6=−9−6

−3x=−15

-3x/-3=-15/-3

x=5

Answer:

[tex]6400\ \text{N}[/tex]

Step-by-step explanation:

[tex]\dfrac{m}{t}[/tex] = Mass flow rate of water = 320 kg/s

[tex]m[/tex] = Mass of water on the door

[tex]t[/tex] = Time

[tex]v[/tex] = Velocity of water on the door = 20 m/s

Force is given by

[tex]F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}[/tex]

The average force is exerted by the stream of water is [tex]6400\ \text{N}[/tex].

Answer:

Minimum value = 1750

Maximum value = 1849

Step-by-step explanation:

Given that:

Number of people who came for match = 1800 (to the nearest hundred)

The maximum. And minimum number of people who came are ;

When rounding to tbe nearest hundred , the tens value which is after the the hundred value is either rounded to 0 or 1 depending on whether the the value is below 5 or greater than or equal to 5 respectively.

Hence,

Minimum value = 1750

Maximum value = 1849

Answer:

58°

Step-by-step explanation:

A + B + C = 180 °

The smallest value of C is 91.

A + B = 89

A = 2B - 4

2B - 4 + B = 89

3B - 4 = 89

3B = 93

B = 31

A + 31 = 89

A = 58

c

you need to find the slope and then y intercept

m=y2-y1/x2-x1

so m=2

now y intercept

3=2(4)+b

solve for b

u get -5

therefore

y=2x-5

Answer:

Step-by-step explanation:

(x-9)/5))(5) = 2(5)

answer is B

Answer:

Slope/m=3, y-intercept=5

Step-by-step explination

2y-6x=10

Factor out the common term of two

2y/2-6x/2=10/2      /=dividing

y-3x=5

Add 3x to both sides

y-3x+3x=5+3x

Simplify

y=5+3x

To get the slope-intercept form (y=mx+b)

y=3x+5
