Given the equation f(x) = (x + 3)2 – 8, fill in the blanks:
Neko [114]
Quadratic f(x) = (x -h)² +k has vertex (h, k) and axis of symmetry x=h. When k is negative, the number of real solutions is 2, because both branches of the function cross the x-axis.

In your equation, h = -3 and k = -8.

Axis of symmetry: x = -3
Vertex: (-3, -8)
Number of real solutions: 2

M∠a=(48−x)°m∠b=(9x−38)°m∠c=90°
Pachacha [2.7K]

<u>The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.</u>

Answer:

<em>x = 10</em>

Step-by-step explanation:

<u>Internal Angles of a Triangle</u>

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10

A train is traveling at a constant speed of 90 miles per hour. How many feet does it travel in 10 seconds? Remember that 1 mile
Flauer [41]

Hi

1 mile = 5280 feet  

at  90 mile per hour, you have  5280 *90  = 475 200 feets  

an hour is  60*60 = 3600 second  

so in 1 second the train travel  :  475 200 /3600 = 4752 /36 = 132 feets

so in 10 seconds  :  132*10 = 1320 feets.
