So in the photo, I was trying to do an order of operations problem with photomath. But I don’t like to cheat without understandi

ng something, and here I don’t understand.
Photomath subtracted 15-3 first because it’s in para thesis. But there is a 2 next to the parentheses so aren’t you supposed to distribute the 2 to the 15 and 3 and THEN subtract? Or do you not distribute? If so, why?

Answer:

the answer of the complete equation is 0

Step-by-step explanation:

first you multiply by 2 all in the parenthesis, 2(15) and 2(3) you got a 30. Then you do the exponents 3(3) is 9

so you got like this= 30-6+9(4)

You multiply 9 and 4=

30-6+36

and the answer is 0

Two lines are perpendicular if their slope m and m' satisfy the equation

mm'=-1

The slope of the given line is 4, because the line is written in the slope-intercept y=mx+q, where m is the slope.

So, the perpendicular slope is

4m'=-1 \iff m'=-\dfrac{1}{4}

So, we want a line with slope -1/4 and passing through (-1,3). We can use the formula

y-b=m(x-a)

for the line passing trough (a,b) with slope m:

y-3=-\dfrac{1}{4}(x+1) \iff y=-\dfrac{1}{4}x-\dfrac{1}{4}+3\iff y=-\dfrac{1}{4}x+\dfrac{11}{4}

The function(t)--4.87+18.75 is used to model the height of an object projected in the air, where h() is the height in
NNADVOKAT [17]

The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.

<h3>How to calculate the domain of the function?</h3>

In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:

0= -4.87t² + 18.75t.

4.87t(-t + 3.85) = 0

t = 0 or t = 3.85.

Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).

<h3>How to calculate the range of the function?</h3>

h(t) = -4.87t² + 18.75t

h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)

h(t) = -4.87(t - 1.925)² + 18.05

Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).
