Answer:

A. Minimum

Step-by-step explanation:

Given function:

y = 4x² + 9x - 2

This is a quadratic function with positive leading coefficient.

It means the graph of the function opens up and therefore it has minimum value of the function at the vertex.

Correct answer choice is A

What is the missing side length? (Use Pythagorean Theorem)

Vedmedyk [2.9K]

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

$a^{2} + b^{2} = c^{2} \\$

Now we can insert values into the equation.

$a = 15\\b = b\\c = 25\\$

Now we can plug these ☝ values into the Pythagorean Theorem:

$15^{2} + b^{2} = 25^{2}\\$

After we solve for $b$ we get:

$b^{2} = 400\\b = 20$

Find the values of x and y.

malfutka [58]

Answer:

y=57, x=77

Step-by-step explanation:

The line that creates x-3 is parrelell to the line that makes 74 degrees

You know that x-3=74

When you simplify you get x=77

Now that you know that x-3=74 you can add all the angles to 180 because they are a supplementary angle

74+41+(y+8)=180, then simplify

115+y+8=180, simplify more

123+y=180

y=57
