Put the coordinates of the points to the equations of the functions and check:
for (1, 4)
y = 5x + 4 → 4 = 5(1) + 4 → 4 = 5 + 4 → 4 = 9 FALSE
y = (x + 1)² → 4 = (1 + 1)² → 4 = 2² → 4 = 4 CORRECT
y = (x + 3)² → 4 = (1 + 3)² → 4 = 4² → 4 = 16 FALSE
y = 7x - 5 → 4 = 7(1) - 5 → 4 = 7 - 5 → 4 = 2 FALSE
Only y = (x + 1)².
Check other points:
for (2, 9)
9 = (2 + 1)² → 9 = 3² → 9 = 9 CORRECT
for (3, 16)
16 = (3 + 1)² → 16 = 4² → 16 = 16 CORRECT
<h3>Answer: Only y = (x + 1)²</h3>
Hi there
The formula is
A=p (1+r/k)^kn
A future value 3000
P present value?
R interest rate 0.04
T time 5years
K compounded quarterly 4
We need to solve for p
P=A÷(1+r/k)^kn
P=3,000÷(1+0.04÷4)^(4×5)
P=2,458.6 round your answer to get
P=2459 this the amount should be deposited
Good luck!
Answer:
17
Step-by-step explanation:
< ABD = <ABC + < CBD
Substitute in what we are given
87 = 9x-1 + 6x+58
Combine like terms
87 = 15x +57
Subtract 57 from each side
87-57 =15x +57-57
30 = 15x
Divide by 15
30/15 =15x/15
2=x
We want to find <ABC
<ABC = 9x-1
= 9*2-1
=18-1
=17
Answer:
C
Step-by-step explanation:
75 divided by 3 is equal to 25 therefore it is 3 feet per 1 second they will travel 30 feet in 10 seconds
Answer:
21.3 feet
Step-by-step explanation:
In the right triangle Δ ABC, the ∠ C = 90° and ∠ A = 25°.
Now, length of BC = 9 inches and length of the hypotenuse i.e. AB is c that we have to calculate.
Now, using trigonometry we can say that
⇒ feet ≈ 21.3 feet. (Answer)
