Solve the equation f(x) = -4x2 – 3x + 2 using the quadratic formula.
a. X=-1.17 and x = 0.43
b. x = 0.58 and x = 4.18
C. X = -4,X = -3, x = -2
d. x = 1.12 and x = 3.53
Need answer ASAP!
The solution f(x) = -4x2 – 3x + 2 is x=-1.17 and x = 0.43
The correct option is (A)
What is Quadratic equation ?Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given equation is :-4x²-3x+2
using the Quadratic Formula where
a = -4, b = -3, and c = 2
x = -b ±√b²-4ac/2a
= 3±√9+32/(-8)
= 3± √41/(-8)
x= 3/(-8) + √41/(-8) or x= 3/(-8)- √41/(-8)
x= -1.17 and x= 0.4253

Cylinder A has a radius of 4 inches and a height of 2 inches. Cylinder B has a radius of 2 inches. What is the height of Cylinder B if both cylinders have the same volume? (Hint: Start by finding the volume of Cylinder A.)
Answer:
6
Step-by-step explanation:
Answer:
h=8 in
Step-by-step explanation:
Formula: V=pi r^2 h
Cylinder A:
radius: 4 in height: 2 in
V=pi*4^*2*2
V=pi*16*2
V=pi*32
V=3.14*32
V=100.48
Cylinder B:
radius: 2 in height: ? volume: 100.48
100.48=pi*2^2*h
100.48=pi*4*h
100.48=3.14*4*h
100.48=12.56*h
100.48/12.56=h
h=8 in

Stock in Daenerys Industries has a beta of 1.2. The market risk premium is 5 percent, and T-bills are currently yielding 4.2 percent. The company's most recent dividend was $1.40 per share, and dividends are expected to grow at an annual rate of 5 percent indefinitely. If the stock sells for $30 per share, what is your best estimate of the company's cost of equity?
Answer:
The best estimate of the company's cost of equity is 10.05%.
Step-by-step explanation:
Using growth rate model formula, the cost of equity can be calculated as follows:
Cost of equity as per growth rate model = (D1 / P) + g ................ (1)
D1 = Most recent dividend * (1 + g) = $1.40 * (1 + 0.05) = $1.47
P = Current price per share = $30
g = Growth rate of dividend = 5%, or 0.05
Substituting the values into equation (1), we have:
Cost of equity as per growth rate model = ($1.47 / $30 ) + 0.05
Cost of equity as per growth rate model = 0.099. or 9.90%
Using Capital Asset Pricing Model (CAPM) formula, the cost of equity can be calculated as follows:
Cost of equity as per CAPM = Risk free rate + (Beta * Market risk premium) = 4.2 + (1.2 * 5) = 10.20%
Therefore, we have:
Best estimate of Cost of equity = (Cost of equity as per growth rate model + Cost of equity as per CAPM) / 2 = (9.90% + 10.20%) / 2 = 10.05%
Therefore, the best estimate of the company's cost of equity is 10.05%.

Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.
Answer:
Bus B travels faster.
Step-by-step explanation:
The graph of the question in the attached figure
we know that
the linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
x ---> is the time in hours
y ---> is the distance in miles
In this problem we have
Bus A
The slope of the linear equation represent the speed of the bus
so
The speed of bus A is
Bus B
Find the slope
take two points from the graph
(0,0) and (3,200)
The formula to calculate the slope between two points is equal to
substitute
Compare the slope Bus A with the slope Bus B
therefore
Bus B travels faster.

Help!!! Consider function f
Which statement is true about function f?
A. The function is increasing over its entire domain
B. The function is continuous
C. As x approaches positive Infinity, f(x) approaches positive infinity
D. The domain is all real numbers
The correct statement of function is the function is continuous.
What is Function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
As, functions approach the same value as x approaches 0.
Now, -x² +4x +1 at x= 2 we get
= -4 + 8 +1 = 5
and, 1/2x + 3 = 1+3= 4
So, we reject the statement.
Now, as x increases without bound,
1/2x +3 increases with bound.
Therefore the statement B is true statement.

i bought a box of fruit snacks worth $9.98, there are 90 packs of fruit snacks in the box. How much is each pack of fruit snacks worth ? please help
Answer:
About $0.11
This is because 0.11 is how much money one pack is Worth.
Answer:
Cost of each pack = $0.11
Step-by-step explanation:
Given information,
→ Total cost of the snacks = $9.98
→ Total packs in the box = 90 packs
Now we have to,
→ Find the cost of each pack.
Let us assume that,
→ Cost of each pack = x
Forming the equation,
→ x × 90 = 9.98
Then the value of x will be,
→ x × 90 = 9.98
→ 90x = 9.98
→ x = 9.98 ÷ 90
→ [ x = $0.11 ]
Hence, the value of x is 0.11.
