Answer:

80 degrees.

Step-by-step explanation:

THe reason why the 3 angles add up to 180 degrees is because they are the 3 angles in the triangle.

So m APB = 180 - 100

= 80 degrees.

50 POINTS. A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)=

Morgarella [4.7K]

Answer:

The domain that makes sense for this function is all values greater than or equal to 0.

Step-by-step explanation:

A ball is thrown into the air from a height of 4 feet at time t = 0. It is modeled by the function:

$h(t)=-16t^2+64t+4$

The domain of the function is time t. The range of the function is the ball's height in the air h.

Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.

Therefore, the domain that makes sense for this function is all values greater than or equal to 0.

In interval notation, this is:

$[0, \infty)$

And as an inequality:

$t\geq 0$

Which value of y would make OP ll LN? A 16 B 24 C 32 D 36

Andreyy89

see the attached figure to better understand the problem

we know that

if OP ll LN

then

by proportion

$\frac{MO}{ML} =\frac{MP}{MN}$

we have that

$MO=28\ units \\ML=28+14=42\ units\\MP=y\ units\\MN=(y+18)\ units$

substitute

$\frac{28}{42} =\frac{y}{(y+18)}\\ \\28(y+18)=42y \\ \\42y-28y=28*18 \\ \\14y=504 \\ \\y=36\ units$

therefore

the answer is

The value of y is $36\ units$

PLS HELP I NEED THIS DONE BY TODAY!!!

Goshia [24]

Answer:

10.08

Step-by-step explanation:

In $\triangle ABC,\: m\angle ACB =90\degree$

$\implies \triangle ABC$ is a right triangle, in which side AB is hypotenuse and sides AC and BC are mutually perpendicular.

By using Pythagoras theorem:

$AC^2 = AB^2 - BC^2 \\ \\ = {(11)}^{2} - {(4.4)}^{2} \\ \\ = 121 - 19.36 \\ \\ = 101.64 \\ \\ \implies \: AC= \sqrt{101.64} \\ \\ \huge\implies \: \red{AC=10.08}$
