Will mark brainlyest: What characteristic of the general quadratic equation below determines whether the corresponding graph has a vertical stretch? y = a(x - h)^2 + k
A: If k is positive
B: If " a " is less than zero
C: If k is negative
D: If :" a " is greater than 1
Answers
Answer:
D
Step-by-step explanation:
First of all, "k" has nothing to do with determining vertical shrink/stretch, and therefore A and C can be eliminated from the choices. A shrink occurs with a fractional "a" value, so "a" must be greater than 1 in order for a vertical stretch to occur.

Which term of the AP 2,8,14,20..... Will be 210 more than it's 60th term?
Answers
Answer:
95th term
Step-by-step explanation:
the nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 2 and d = a₂ - a₁ = 8 - 2 = 6 , then
[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
the 60th term is then
a₆₀ = 6(60) - 4 = 360 - 4 = 356
so 210 more than a₆₀ = 356 + 210 = 566
now equate [tex]a_{n}[/tex] to 566 and solve for n
6n - 4 = 566 ( add 4 to both sides )
6n = 570 ( divide both sides by 6 )
n = 95
Answer:
95th term.
Step-by-step explanation:
The sequence of 2, 8, 14, 20 . . . can be predicted by adding 6 to each successive term. This can be written as 6n+2, where n starts at 0 for the first term.
n Value (6n+2)
0 2
1 8
2 14
3 20
4 26
60 362
---
We want to know what term is 210 more than 362. (362+ 210) = 572
We can solve by using the equation in reverse and solving for n:
(6n+2) = 572
6n = 570
n = 95
The 95th term (572) is greater than the 60th term (362) by 210.
Counselors at Rockport High School and Riverdale High School surveyed the graduating seniors to find out their post-high-school plans. Each student plans to attend college, attend technical school, join the military, or go right into the workforce. The results of the survey are shown in the table.
Answers
The percentage shows that they were 28% more likely to come from Riverdale High school.
How to calculate the percentage?From the information given, the percentage of those from Rockport will be:
= 25/(25 + 44) × 100.
= 25/69 × 100
= 36.23%
The percentage of those from Riverdale will be:
= 44/(25 + 44) × 100.
= 44/69 × 100
= 63.77%
Therefore, the difference will be:
= 63.77% - 36.23%
= 28% approximately.

Find the first four terms, in thousands, of the geometric series. round to the nearest thousand. a1 = a2 = a3 = a4 =
Answers
The geometric series an = 400(1.05)^(n-1) has a common ratio and an initial term
The first four terms are a1 = 400; a2 = 420; a3 = 441 and a4 = 463.05
How to determine the first four terms?The geometric series is given as:
an = 400(1.05)^(n-1)
Substitute 1 for n
a1 = 400 * (1.05)^(1-1)
Evaluate the product
a1 = 400
Substitute 2 for n
a2 = 400 * (1.05)^(2-1)
Evaluate the product
a2 = 420
Substitute 3 for n
a3 = 400 * (1.05)^(3-1)
Evaluate the product
a3 = 441
Substitute 4 for n
a4 = 400 * (1.05)^(4-1)
Evaluate the product
a4 = 463.05
Hence, the first four terms are
a1 = 400; a2 = 420; a3 = 441 and a4 = 463.05

a car uses 9 gallons of gasoline to go 162 miles. how many gallons of gasoline will the same car use to travel 216 miles?
Answers
Answer:
[tex]12\ gallons[/tex]
Step-by-step explanation:
Step 1: Determine the unit rate
[tex]Miles / Gallons[/tex]
[tex]162\ miles / 9\ gallons[/tex]
[tex]18\ miles/gallon[/tex]
Step 2: Determine the amount of gasoline used for 216 miles
[tex]216\ miles * (gallon / 18\ miles)[/tex]
[tex]12\ gallons[/tex]
Answer: [tex]12\ gallons[/tex]
Answer:
12
Step-by-step explanation:
1. Figure out how many miles the car can go with one gallon of gasolline
162 ÷ 9 = 18
1 gallon = 18 miles
2. Figure out how many times 18 can go into 216
216 ÷ 18 = 12
12 gallons = 216 miles
*We do this because we know that every time the car drives 18 miles its uses another gallon of gas.
The car will use 12 gallons of gasoline to travel 216 miles.

Adam's
age is 3 years and 6 months.
Zara's age is 2 years and 11 months.
.
Write Adam's age in months as a fraction of Zara's age in months.
Give your fraction in its simplest form.
Answers
The question is an illustration of fraction division and Adam's age as a fraction of Zara's age is 7/5
How to represent the age as a fraction?The ages are given as:
Adam = 3 years and 6 months
Zara = 2 years and 11 months
Rewrite the ages in months
Adam = 3 * 12 + 6 = 42 months
Zara = 2 * 12 + 11 = 35 months
Adam's age as a fraction of Zara's age is calculated using:
Fraction = Adam/Zara
This gives
Fraction = 42/35
