Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs.
f(x)=(x-3)(x+8
a) x-intercepts are _________
b) midpoint of the x-intercepts is ___________
c) the extreme value is _______________
d) f(_) = ______________
Answer:
(a) (3, 0) and (-8, 0)
(b) (-2.5, 0)
(c) x = -2.5
(d) f(-2.5) = -30.25
Step-by-step explanation:
Given quadratic function:
[tex]f(x)=(x-3)(x+8)[/tex]
Part (a)The x-intercepts are when [tex]f(x)=0[/tex]
[tex]\implies f(x)=0[/tex]
[tex]\implies (x-3)(x+8)=0[/tex]
[tex]\implies (x-3)=0 \implies x=3[/tex]
[tex]\implies (x+8)=0 \implies x=-8[/tex]
Therefore, the x-intercepts are (3, 0) and (-8, 0)
Part (b)Midpoint between two points:
[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad[/tex]
[tex]\textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]
[tex]\implies \textsf{Midpoint of the x-intercepts}=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-2.5},0\right)[/tex]
Part (c)The extreme point of a quadratic function in the form [tex]f(x)=ax^2+bx+c[/tex] is:
[tex]x=-\dfrac{b}{2a}[/tex]
Therefore, expand the function so that it is in standard form:
[tex]\implies f(x)=x^2+5x-24[/tex]
[tex]\implies a=1, b=5[/tex]
Therefore, the extreme value is:
[tex]\implies x=-\dfrac{5}{2}=-2.5[/tex]
Alternative method
A quadratic function has an extreme value at its vertex.
The x-value of the vertex is the midpoint of the x-intercepts.
Therefore, the extreme value is x = -2.5
Part (d)[tex]\begin{aligned}\implies f(-2.5) & =(-2.5-3)(-2.5+8)\\& = (-5.5)(5.5)\\& = -30.25\end{aligned}[/tex]

At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.14 and the probability that the flight will be delayed is 0.06. The probability that it will not rain and the flight will leave on time is 0.82. What is the probability that it is raining and the flight is delayed? Round your answer to the nearest thousandth.
Answer:
0.892
Step-by-step explanation:
The probability that it is raining and the flight is delayed is 0.008.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, the probability that it will rain is 0.14 and the probability that the flight will be delayed is 0.06.
Let P(A)=0.14 and P(B)=0.06
Here, P(A and B)=P(A)×P(B)
= 0.14 ×0.06
= 0.0084
= 0.008
Therefore, the probability that it is raining and the flight is delayed is 0.008.

The following sphere has a diameter of 18 cm.
Answer: A
Step-by-step explanation:
Solve for x,
x = 10
x = 15
x = 8
x = 12
[tex]~~~~~~(8x-17)+(3x+2)+63 = 180\\\\\implies 11x +48=180\\\\\implies 11x = 180-48\\\\\implies 11x = 132\\\\\implies x= \dfrac{132}{11}\\\\\implies x= 12[/tex]
Answer:
x = 12.
Step-by-step explanation:
The sum of the 3 angles is 180, so:
8x - 17 + 3x + 2 + 63 = 180
11x -15 + 63 = 180
11x = 180 + 15 - 63
11x = 132
x = 132/11 = 12

A biased coin is flipped twice.
The probability of the coin landing on tailsis 0.4. Find the probability the coin lands on tails exactly once.
Answer:
0.48.
Step-by-step explanation:
There are 2 ways that a tail lands once:-
Tail + head or
head + tail.
Prob(Tail on one throw) = 0.4
Prob(Head on one throw) = 1 - 0.4 = 0.6.
Prob(Tail first then head) = 0.4 * 0.6 = 0.24
Head then tail has the same probability (0.6*0.4).
So the requred probability = 0.24 + 0.24
= 0.48.
4 If 2 is a zero of
polynomial f(x) = ax² - 3(a-1)x-1,
then find the value of a.
Answer:
a = 2.5
Step-by-step explanation:
It is mentioned that 2 is a zero of the polynomial f(x) = ax² - 3(a - 1)x - 1
So that means :
⇒ f(x) = 0
⇒ x = 2
Substituting and solve for a :
⇒ 0 = a(2)² - 3(a - 1)(2) - 1
⇒ 0 = 4a - 6(a - 1) - 1
⇒ 0 = 4a - 6a + 6 - 1
⇒ 2a = 5
⇒ a = 2.5

a basket contains red, green, yellow apples. An apple is selected at random if p(red) is 2/5 P(yellow) is 1/4 what is p(green)?
A. 3/20
B. 7/20
C. 1/10
D. 13/20
The probability of getting the green apple is 7/20 option (B) 7/20 is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
P(red) = 2/5
P(yellow) = 1/4
The sum of the probability of the event is 1.
P(red) + P(yellow) + P(green) = 1
2/5 + 1/4 + P(green) = 1
P(green) = 1 - (2/5 + 1/4)
P(green) = 7/20
Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.
