The last one is correct. For the first one it starts at -5 then decreases 5 more degrees for a total of -10. For the last one, you start 24 meters below sea level (-24m) and go up 24 which has an end value of 0.

No it was the last answer. Because decrease is -5 and -5 which makes -10

Please help i am super confused on what to do :)

Answer:

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}

So:

\displaystyle \tan(20)=\frac{h}{25}

Therefore:

\displaystyle h=25\tan(20)

Use a calculator. Ensure your calculator is in the correct mode (degrees mode):

h\approx 9.1\text{ yards}

The goal post is around 9.1 yards tall.

0.89 \times 1.39 = 1.24
You paid $1.24 for the apples

Simplify. Show your work.<br> (2√(5)+3√(7))^2
frozen [14]

Answer:

The answer is: 83 + 12√35

(a + b)² = a² + 2ab + b²

In (2√5 + 3√7)², a = 2√5, b = 3√7

Just substitute a and b:

(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² = 

           = 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =

           = 4 * 5 + 12 * √(5*7) + 9 * 7 =

           = 20 + 12 *√35 + 63 =

           = 83 + 12√35

What’s the axis of symmetry and the vertex of x^2-4x-32
konstantin123 [22]
<span>x^2 -4x -32
</span>a =1b= -4c= -32
The x,y points of the vertex are usually referred to as Vertex = (h, k)where h = -b / (2 * a)
h = --4 / (2 * 1)h = 4 / 2h = 2
k = ah^2 +bh + ck =1*4 -4*2 -32k = 4 -8 -32k = -36
vertex = (2, -36)axis of symmetry = x position = 2
