Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = 4x2 + 24x + 30?The graph of f(x) = x2 is widened. The graph of f(x) = x2 is shifted left 3 units. The graph of f(x) = x2 is shifted up 30 units. The graph of f(x) = x2 is reflected over the x-axis.

state the type of roots for a quadratic equation explaining how the discriminant helps you determine the type

Answers

You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts

2 roots means the discriminan is positive in other words

D>0

When the discriminan is 0, D=0 we have exactly one x-intercept.

Discriminan D=0

and finally, if the discriminan were negative

D=0

then there is no solution or root at all.

r = (1/t)(A/P - 1)

r = (1/9)((300/81) - 1)
Reduce the expression by cancelling the common factors.
r=(1/9)(100/27−1)

Combine 100/27 and −1 using a common denominator.
r=(1/9)(100−1⋅27/27)

Simplify the numerator.
r=(1/9)(73/27)

r = 0.30041152

converting r decimal to a percentage
R = 0.30041152 * 100 = 30.0412%/year

A toy rocket was launched from the ground. The function f(x) = -16x2 + 160x shows the height of the rocket f(x), in feet, from the ground at time x seconds.What is the axis of symmetry of the graph of f(x), and what does it represent?

These are the choices:
x = 10; it takes 10 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 10; it takes 10 seconds to reach the maximum height and 20 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 5 seconds to fall back to the ground

33 POINTS PLZ. Solve the following equations. a) 2x + 8 = x + 25 + 8 b) 3x + 23 = 2x + 59 c) 5 + 12 = 17 d) 2x - 4 = x + 9 e) 5x - 10 = 4x - 12

Answers

Hi there!

a)
$2x + 8 = x + 25 + 8$
Collect terms

$2x + 8 = x + 33$
Subtract x

$x + 8 = 33$
Subtract 8

$x = 25$

b)
$3x + 23 = 2x + 59$
Subtract 2x

$x + 23 = 59$
Subtract 23

$x = 26$

c)
$5 + 12 = 17$
This is not an equation, but the sum of 5 and 12 is 17, so it's true.

d)
$2x - 4 = x + 9$
Subtract x

$x - 4 = 9$
Add 4.

$x = 13$

e)
$5x - 10 = 4x - 12$
Subtract 4x

$x - 10 = - 12$
Add 10

$x = - 2$
