Michela’s skateboard ramp is at an incline of 40°. When she attempts a trick on the ramp, she finds that it is too steep. She ad

marissa [1.9K]

Answer:

22.7604763 degrees

Step-by-step explanation:

Note that the answer is NOT 20 degrees.

She adjusted the ramp to half the original incline

Therefore we have tan 40 = x = 0.839099631.

We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815

Taking the arctan of both sides, we get

y = arctan(0.419549815) = 22.7604763 degrees

Ivan

Answer:

$8\frac{3}{4}$ cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

$1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4}$

$= 8\frac{3}{4}$ cups.

Can someone please help me ASAP (radical functions)

Afina-wow [57]

Answer:

Step-by-step explanation:

To find the y- intercept, let x = 0 in the equation

Given

f(x) = - $\sqrt{5x+2}$ - 1, then

f(0) = - $\sqrt{5(0)+2}$ - 1 = - $\sqrt{2}$ - 1 ← y- intercept,

(0, - $\sqrt{2}$ - 1 ) ← coordinates of y- intercept
