Anika [276]

Ok so I’m assuming the question is how the tall is we need to find the Angle of the sun so

Student : 175

Shadow: 2.3

Hypotenuse: 175.0151136

Using -cos(175/175.0151136) we find the

Suns angle: .753 Above him/her

Our tree’s shadow:8.2

Using the suns angle we use cos(x

Quick question
zaharov [31]

Answer:

False

Step-by-step explanation:

Let us evaluate the problem using the proper order of operation:

           4x − 2(5x − 1)

To solve this problem, we use the order of operation called PEMDAS;

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Now, since operations inside the parentheses are of the utmost priority, let us solve this;

             4x − 2(5x − 1)

            = 4x - 10x +2

            = -6x + 2  or 2 - 6x

We see that the solution give is false.

The equation
faust18 [17]

Answer:

best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!

Step-by-step explanation:

y = -  0.37 {x}^{2} + 6.15x + 52.3  \\ y =  - 0.37 ({9}^{2} ) + 6.15(9) + 52.3 \\ y =  - 0.37(81) + 6.15(9) + 52.3 \\ y =  - 29.97 + 55.35 + 52.3 \\ y = 77.68
