Answer:
y + 2 = -2(x - 3)^2
Step-by-step explanation:
We can see immediately that the vertex is at (3, -2).
The vertex form of the equation of a parabola is
y - k = a(x - h)^2.
If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2. But seeing that this particular parabola opens downward, the equation is
y + 2 = -2(x - 3)^2.
Check: Does the point (2, -4) satisfy this equation?
-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.
Tell whether each outcome is impossible, unlikely, as

Is this a fact or opinion? Explain your answer.
If two sets of data have the same mean, they must be the same set of data.
Answer:
opinion
Step-by-step explanation:
2 different sets of data can have the same mean:
for example
4, 5, 6 ---> has a mean of 5
2,6,7 ---> also has a mean of 5
hence it is NOT a fact that if the means are the same, that it must be the same data set
Simplify (3v5+8v3−10v2)−(−12v5+4v3+14v2) . Write answer in standard form.
Answer:
15v^5+4v^3-24v^2
Step-by-step explanation:
Distribute the Negative Sign:
=3v5+8v3−10v2+−1(−12v5+4v3+14v2)
=3v5+8v3+−10v2+−1(−12v5)+−1(4v3)+−1(14v2)
=3v5+8v3+−10v2+12v5+−4v3+−14v2
Combine Like Terms:
=3v5+8v3+−10v2+12v5+−4v3+−14v2
=(3v5+12v5)+(8v3+−4v3)+(−10v2+−14v2)

The probabilities of a positive response to two government programs from citizens in eight cities are given in the table. What is the chance of
a positive response for program 1, given that the individual is from Houston?
ОА
68.896
OB.
69.796
OC.
79.496
OD
insufficient data
Answer:
The correct option is (B) 69.7%.
Step-by-step explanation:
The table provided represents the probabilities of a positive response to two government programs from citizens in eight cities.
The probabilities mentioned in the table are conditional probabilities, i.e. the probability of a positive response for program 1, given that the individual is from city x.
The probability a positive response for program 1 from an individual from Houston is 69.7%.
Then the conditional probability of a positive response for program 1, given that the individual is from Houston is 69.7%.
Thus, the correct option is (B).
what is the surface area of a cone in terms of pi with a diameter of 14cm and a slant height of 20cm
Answer:
476 Pi cm^2
Step-by-step explanation:
The surface area of a cone is given by the formula:
● Sa = Pi× r^2 + Pi×r×l
r is the radius and l is the slant heigth.
■■■■■■■■■■■■■■■■■■■■■■■■■■
We are given that:
● r = 14 cm
● l = 20 cm
Let's calculate Sa
● Sa = Pi×14^2 + Pi × 14 × 20
● Sa = 476 Pi cm^2
The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely with paper. How much paper do you need?
Answer:
Total paper required = 165 cm²
Step-by-step explanation:
Paper required to cover the entire block = (Surface area of the prism at the base - area of the top of the prism) + Lateral surface area of the pyramid
Surface area of the rectangular prism = 2(lb + bh + hl)
(here l, b, h are the length, width and height respectively)
= 2(5×5 + 5×4 + 4×5)
= 2(25 + 20 + 20)
= 2×65
= 130 cm²
Area of the top of the prism = (side)²
= 5²
= 25 cm²
Lateral area of the square pyramid = 4 × Area of one lateral side
= 4 × [tex][\frac{1}{2}(\text{Base})(\text{Height})][/tex]
= 4 × [tex][\frac{1}{2}(5)(6)][/tex]
= 60 cm²
Total paper required = (130 - 25) + 60
= 105 + 60
= 165 cm²

what number is not part of the solution set to the inequality below?
w - 10 less than or equal to 16
Answer:
If you have this as an answer, 27
(The question is "what number is not part of the solution set to the inequality below?)
Step-by-step explanation:
w - 10 ≤ 16
w - 10 + 10 ≤ 16 + 10
w ≤ 26
11, 15, and 26 are all either less than, or equal to 26. Only 27 is not.

Answer:
Answer is A
Step-by-step explanation:
(14x^4y^6)/(7x^8y^2)
because everything is one term, you can split into three terms
14/7, x^4 / x^8 , and y^6/y^2
multiplying these three terms will get us the starting term
14/7 = 2
x^4 / x^8
with division of exponents, you subtract the smaller exponent (4), from the big exponent (8), and leave it on the same side (bottom) as the big exponent
1/x^4
same thing with our y's
y^6/y^2
this time, the term stays on the top
y^4
take the simplified terms and multiply them together
(2) * (1/x^4) * (y^4) =
A: (2y^4) / (x^4)
Gracie has 1/2 of a cantaloupe that she wants to divide. How many 's 1/8 of a cantaloupe are there in 1/2 of a cantaloupe?
Answer:
4/8
Step-by-step explanation:
Dividing a whole cantaloupe into eighths will give you 8/8 or 1. When it is cut in half then divided there is one half of 8/8 or there are 4/8 in one half. This is true because 1/2 and 4/8 are equal terms.

Answer:
(x+4)
Step-by-step explanation:
Since area is width times length, you can just factor the area to get the width and length
You factor to get (x+4)(x+7)
Since (x+7) is the length, (x+4) must be the width
Answer:
(x + 4) m
Step-by-step explanation:
[tex]Area \: of \: rectangle = length \times width \\ \\ width = \frac{Area \: of \: rectangle}{length} \\ \\ = \frac{ {x}^{2} + 11x + 28 }{x + 7} \\ \\ = \frac{ {x}^{2} + 7x + 4x + 28}{x + 7} \\ \\ = \frac{ x({x} + 7) + 4(x + 7)}{x + 7} \\ \\ = \frac{ ({x} + 7) (x + 4)}{x + 7} \\ \\ = (x + 4) \: m \\ \\ \red{ \boxed{\bold {\therefore \: width \: = (x + 4) \: m}}} [/tex]

What is equivalent to log2(7)
A.7^2
B.2^7
C.7log(2)
D.log(7)/log(2)
E. Log(2)/log(7)
Answer:
D
Step-by-step explanation:
Using the changing base formula, log base 2 raised to 7 can be written as log7/log2
The correct answer is D. log(7) / log(2).
To find the equivalent of log2(7), you can use the change of base formula for logarithms.
The change of base formula states that log base a of b is equal to log base c of b divided by log base c of a.
In this case, we want to find the equivalent of log2(7), so we can use the change of base formula with base 10 as follows:
log2(7) = log(7) / log(2)
Therefore, the correct answer is D. log(7) / log(2).
