How does the graph of y=4x+7 differ from the graph of y=4x

Schach [20]

Find any two points on the line.

x=0⇒y=4(0)+7=7⇒ Point 1: (0,7)

x=−1⇒y=4(−1)+7=3⇒ Point 2: (−1,3)

Step 2: Plot the two points from Step 1

Step 3: Draw a straight line through both points

The formula for the volume of a sphere is the following:

$V= \dfrac{4}{3} \pi r^3$

Plug in V=5000π and solve for the radius.

$5000 \pi = \dfrac{4}{3} \pi r^3$

Divide both sides by $\pi$

$5000 = \dfrac{4}{3} r^3$

Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).

$r^3=3750$

Take the cube root of both sides

$r \approx 15.5$

Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:

$S=4 \pi r^2$

Plug in r=15.5

$S \approx 3033$

The second choice is your answer.

Please help thank you very much and show all work

Question 1:

Angle D and angle E are congruent because they are alternate interior angles. Let's make an equation.

$5(x-2)=x+14$

Use the distributive property

$5x-10=x+14$

Add both sides by 10 and subtract both sides by x

$4x=24$
$x=6$

Plus this in and you get 20 for both of them (they're supposed to be congruent).

Your answer is the first choice.

Question 2:

Use the sine. The sine is the opposite leg divided by the hypotenuse. Divide the sine from 400 to get our answer.

$\dfrac {400}{sin(7)} \approx 3282$

Your answer is the third choice.

Question 3:

Use the tangent. The tangent is the opposite side divided by the adjacent. Divide 203 by the tangent of 22 degrees.

$\dfrac{203}{\tan(22)} \approx 502.4$

Your answer is the third choice. I hope this helps! :)

Part F

Answer:

The geometric mean of the measures of the line segments AD and DC is 60/13

Step-by-step explanation:

Geometric mean: BD² = AD×DC

BD = √(AD×DC)

hypotenuse/leg = leg/part

ΔADB: AC/12 = 12/AD

AC×AD = 12×12 = 144

AD = 144/AC

ΔBDC: AC/5 = 5/DC

AC×DC = 5×5 = 25

DC = 25/AC

BD = √[(144/AC)(25/AC)]

BD = (12×5)/AC

BD= 60/AC

Apply Pythagoras theorem in ΔABC

AC² = 12² + 5²

AC² = 144+ 25 = 169

AC = √169 = 13

BD = 60/13

The geometric mean of the measures of the line segments AD and DC is BD = 60/13
