Answer:

Step-by-step explanation:

See that the slope of the parabola changes at x=4

And left of x=4, the slope is positive, meaning the value is increasing (you can also see it directly from the graph)

Right of x=4, the slope is negative, meaning the value of the graph is decreasing. Thus the answer is A

23.6

Step-by-step explanation:

Hello There!

So they want us to find ∠Z

We are given ∠Zs opposite side length and the length of the hypotenuse

Sine refers to opposite divided by hypotenuse

So we can use sine to solve for ∠Z

$SinZ=\frac{6}{15} \\\frac{6}{15} =.4\\SinZ=.4\\Z=arcsin(.4)\\Z=23.57817848$

Note: arcsin is the inverse of sin

Other way we could find ∠Z:

We could also use law of sines which states that a side length divided by sin(its opposite angle) is equal to a different side length divided by sin ( its opposite angle)

So specifically for this triangle

$\frac{15}{sin90} =\frac{6}{sinZ}$

step 1 multiply each side by 6

note : flip the fraction

$\frac{6sin90}{15} =sinZ\\\frac{6sin90}{15}=.4\\.4=sinZ\\arcin(.4)=23.57817848\\Z=23.57817848$

Then our final step is to give our answer to the first decimal place

so the answer would be 23.6

If the measures of the angles in the following triangle were listed in increasing order, which measure would be second? (2x+24)

Andru [333]

Answer:

x²+1 is the second

Step-by-step explanation:

2x+24=40°

4x+43=75°

x²+1=65°

(2x+24) + (4x +43) + (x²+1)=180

x²+6x+68=180

x1=-14

x2=8

since there's no negative angle, we'll use x=8

A rectangular prism has a volume of 137.54ft the length is 2.3 feet and the height is 13 feet. Write and solve an equation to de

patriot [66]

All you have to do is multiply 2.3 by 13 together to get 29.9. Then you would subtract that by the total volume which would get 107.64. That's the width.
