For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the x-axis at each x -intercept.
f(x) = 3(x + 7)(x + 3)^2?
A? B? C? D?
Answers
Answer:
B
Step-by-step explanation:
You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.
[tex]x+7=0\\x+3=0[/tex]
Solve them both and you get:
[tex]x=-7\\x=-3[/tex]
Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.
Therefore the answer is B since that agrees with everything we said.

On a child’s birth, a deposit of $2000 was put into an account that pays 5% interest compounded annually. How much is in the account after 18 years?
Answers
Answer: $4,813.24
Step-by-step explanation:
This requires the use of a future value formula because we are to find the value of an amount in future after compounding it over a certain period.
Future Value = Amount * (1 + rate) ^ number of years
= 2,000 * ( 1 + 5%)¹⁸
= $4,813.24
In 18 years, the $2,000 would have increased to $4,813.24.

Step-by-step explanation:
All quadrilaterals' interior angles sum to 360°, so to solve one angle in the trapezoid, we can subtract the angles we have from 360.
So x=360-(60+128+95)=77°
x=77°

The area of a trapezoid is (1/2)h(b1 + b2). A trapezoid has an area of 50 in2. If the bases are 12 and 8 inches, what is the height?
Answers
Answer:
5 in.
Step-by-step explanation:
Given that
b1 = 12
b2 = 8
A = 50
Formula is (1/2)h(b1 + b2), on substituting
50 = 1/2 * h(12 + 8)
50 = 1/2 * h(20)
100 = 20h
h = 100/20
h = 5
The height is 5 in

The sketch shows part of the graph y=ab^x
Answers
Answer:
a = 3, b = 2
[tex]y = 3\cdot 2^x[/tex]
Step-by-step explanation:
[tex]y = ab^x\\3 = ab^0\\12 = ab^2\\~\\3=ab^0=a\cdot 1 = a\\a = 3\\~\\12 = ab^2 = 3b^2\\4 = b^2\\b = 2 \vee b = -2[/tex]
but we know from the graph being defined and positive, that b cannot be -2
b = 2
The value of a is 3 and value of b is 2.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The graph is y=abˣ
The points with coordinates (0, 3) and (2, 12) lie on the graph.
We need to find the values of a and b.
The point (0, 3)
3=ab⁰
a=3
Now point (2, 12)
12=ab²
Now plug in a value as 3
12=3b²
Divide both sides by 3
12/3=b²
4=b²
b=2
Hence, the value of a is 3 and value of b is 2.
