Answer:

$\huge\boxed{\sf Graph\ C}$

Step-by-step explanation:

<u>Given equation is:</u>

$\sf y = \frac{3}{4} x -3$

So, Slope = 3/4 and y-intercept = -3

<u>Let's find the slope and y-intercept for each graph:</u>

$\rule[225]{225}{2}$

Graph A:

Let's pick two coordinates to find the slope:

Coordinates are (5,1) and (0,-3)

$\sf Slope = \frac{y2-y1}{x2-x1} \\\\Slope = \frac{-3-1}{0-5} \\\\Slope = \frac{-4}{-5} \\\\Slope = \frac{4}{5}$

So, This is not the required Graph.

$\rule[225]{225}{2}$

Graph B:

Graph B is also not the required graph because it's y-intercept is 3 and not -3 (y-intercept is the point where the value of y is zero)

$\rule[225]{225}{2}$

Graph C:

The left graph is graph C. So, This is the correct answer!

$\rule[225]{225}{2}$

Hope this helped!

kow [346]

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.

Find the values of the missing sides in the parallelogram given.

natta225 [31]

Given:

m∠B = 44°

Let's find the following measures:

m∠A, m∠BCD, m∠CDE

We have:

• m∠A:

Angle A and Angle B are interior angles on same side of a transversal.

The interior angles are supplementary.

Supplementary angles sum up to 180 degrees

Therefore, we have:

m∠A + m∠B = 180

m∠A + 44 = 180

Subtract 44 from both sides:

m∠A + 44 - 44 = 180 - 44

m∠A = 136°

• m,∠,BCD:

m∠BCD = m∠A

Thus, we have:

m∠BCD = 136°

• m∠CDE:

Angle C and angle CDE form a linear pair.

Linear pair of angles are supplementary and supplementary angle sum up to 180 degrees.

Thus, we have:

m∠D = m∠B

m∠D = 44°

m∠CDE + m∠D = 180

m∠CDE + 44 = 180

Subract 44 from both sides:

m∠CDE + 44 - 44 = 180 - 44

m∠CDE = 136°

ANSWER:

• m∠A = 136°

•

• m∠BCD = 136°

•

• m∠CDE = 136°

Find the length of the curve. R(t) = 7t, 3 cos(t), 3 sin(t) , −2 ≤ t ≤ 2

Leviafan [203]

we are given

$r(t)=(7t,3cos(t),3sin(t))$

we can find x , y and z

$x=7t,y=3cos(t),z=3sin(t))$

now, we can use arc length formula

$L=\int\limits^a_b {\sqrt{(x')^2+(y')^2+(z')^2} } \, dt$

now, we can find derivative

$x'=7,y'=-3sin(t),z'=3cos(t))$

now, we can plug values

and we get

$L=\int _{-2}^2\sqrt{7^2+\left(-3\sin \left(t\right)\right)^2+\left(3\cos \left(t\right)\right)^2}dt$

$L=\int _{-2}^2\sqrt{7^2+9}dt$

$=\sqrt{58}\cdot \:2-\left(-2\sqrt{58}\right)$

$L=4\sqrt{58}$ ...........Answer

How would I solve this?

lutik1710 [3]

Answer:

It is rotated by 72 degrees.

Step-by-step explanation:

Since it is a regular polygon,

when u connect all the corners of it to the middle of the polygon, they will meet at a point i.e, CENTER.

The sum of the angles subtended by all the sided at the center will be 360 degrees.

As there are 60 sides, the angle subtended by each side at the center will be 6 degrees.

Because,

$\frac{360}{60} = 6$

As the polygon rotates every minute and it is rotated for 12 minutes,

$12*6 = 72$

( For every minute, it will be rotated by 6 degrees.

so, for 12 minutes it should be rotated by 12 times 6 ( 12*6) = 72 degrees)

So, after 12 minutes it will be rotated by 72 degrees.
