Elaine whill not make any additional deposits to or withdrawls from her account. What will be the balance in Elaine's account at the end of 3 years. Round your answer to the nearest whole dollar
Answer:
$1,061
Step-by-step explanation:
2% of 1000 is 20.
If 2% is compounded yearly, then
year one- $1,020
year two- $1,040.40
year three- $1,061.21
Rounded to the nearest whole dollar, Elaine would have $1,061 in her savings account after three years.

Given center C and a point P on a circle, find its equation. C(-2, 7) and P(1, 11)
A. (x - 1)2 + (y - 11)2 = 5
B. (x + 2)2 + (y - 7)2 = 5
C. (x - 1)2 + (y - 11)2 = 25
D. (x + 2)2 + (y - 7)2 = 25
The equation of a circle with center at [tex]C(-2, 7)[/tex] and Point [tex]P(1, 11)[/tex] will be [tex](x+2)^2+(y-7)^2=25[/tex] .
What is equation of a circle ?
Equation of a circle is written in the form [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius.
We have,
Center at [tex]C(-2, 7)[/tex]
i.e. [tex]h=-2[/tex], [tex]k=7[/tex],
And
Point [tex]P(1, 11)[/tex]
i.e. [tex]x=1[/tex], [tex]y=11[/tex]
Now,
To determine Radius of the circle;
[tex]r^2=(x-h)^2+(y-k)^2[/tex]
[tex]r^2=(1-(-2))^2+(11-7)^2[/tex]
[tex]r=\sqrt{3^2+4^2} =\sqrt{25}[/tex]
[tex]r=5[/tex]
So, radius of the circle is [tex]5[/tex] .
Now,
Equation of a circle ;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](x-(-2))^2+(y-7)^2=5^2[/tex]
[tex](x+2)^2+(y-7)^2=25[/tex]
So, the Equation of a circle is [tex](x+2)^2+(y-7)^2=25[/tex] .
Hence, we can say that the equation of a circle with center at [tex]C(-2, 7)[/tex] and Point [tex]P(1, 11)[/tex] is [tex](x+2)^2+(y-7)^2=25[/tex] .

4) Terry missed the sale on a $210 jacket. When he went to purchases it,
he jacket increased to a cost of $262.50 By what percent did the jacket
ncrease in price?
Answer:
The jacket increase by 25% in price.
Step-by-step explanation:
Given that:
Sale price of jacket = $210
New cost of jacket = $262.50
Change = New cost - Sale price
Change = 262.50 - 210 = $52.50
Percent increase = [tex]\frac{Change}{Sale\ price}*100[/tex]
Percent increase = [tex]\frac{52.50}{210}*100[/tex]
Percent increase = 0.25 * 100
Percent increase = 25%
Hence,
The jacket increase by 25% in price.

Lines a and b in the diagram are parallel. Parallel lines a and b are cut by 2 transversals. At the intersection of line a with the transversals, clockwise from top left, the angles are 45 degrees, 95 degrees, blank, blank, B, 40 degrees. At the intersection of b with a transversal, the angles are blank, A, blank, blank. At the intersection of b with the second transversal, the angles are C, blank, blank, blank. Step 1: measure of angle A = 40 degrees (alternate interior angles). Step 2: measure of angle B = 95 degrees (vertical angles). Step 3: measure of angle C = 40 degrees (corresponding angles). Shalini found the sum of the measures of the interior angles of the triangle to be 175°. She knows the sum is supposed to be 180°.

Let A,B, and C be square invertible matrices of the same size. If C has no eigenvalue equal to -1, then (AB + ACB)^-1 is equal to:
a. B^-1 (I + C)^-1*A^-1
b. (I + C)^-1*B^-1*A^-1
c. A^-1B*(I + C)^-1
d. (I + C)^-1*BA^-1
AB + ACB = A (B + CB) = A (I + C ) B
Taking the inverse gives
(A (I + C ) B)⁻¹ = B ⁻¹ (I + C )⁻¹ A ⁻¹
so the answer is (A)
A,B, and C are square invertible matrices of the same size.The correct option is a. [tex]\(A^{-1}(I + C)^{-1}B^{-1}\)[/tex].
Given A, B, and C as square invertible matrices of the same size, we want to find [tex]\((AB + ACB)^{-1}\)[/tex].
Step 1: Factor out B from the expression inside the parentheses:
[tex]\(AB + ACB = B(A + AC)\)[/tex]
Step 2: Use the property that [tex]\((X + Y)^{-1} = Y^{-1}X^{-1}\)[/tex] for invertible matrices X and Y:
[tex]\((AB + ACB)^{-1} = (B(A + AC))^{-1} = (A + AC)^{-1}B^{-1}\)[/tex]
Step 3: Now, use the distributive property of matrix inversion, which states that [tex]\((XY)^{-1} = Y^{-1}X^{-1}\)[/tex] for invertible matrices X and Y:
[tex]\((A + AC)^{-1} = A^{-1}(I + C)^{-1}\)[/tex]
Step 4: Substitute this back into the expression from Step 2:
[tex]\((AB + ACB)^{-1} = (A + AC)^{-1}B^{-1} = A^{-1}(I + C)^{-1}B^{-1}\)[/tex]
So, the correct option is: a. [tex]\(A^{-1}(I + C)^{-1}B^{-1}\)[/tex]

What is the quadratic function?In algebra, a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic, is a polynomial function with one or more variables in which the highest-degree term is of the second degree.
Here we have the two quadratic functions:
f(x) = 4(x - 3)²+ 6
g(x) = -2(x + 1)²+ 4
The x-value of the vertex is the value of x such that the first term becomes equal to zero, so for f(x) the vertex is at x = 3, and the y-value of the vertex is:
f(3) = 0 + 6 = 6
So the vertex is (3, 6)
For g(x) we can see that the vertex is at x = -1, and:
g(-1) = 0 + 4=4
So the vertex is at (-1, 4)
Also, you can see that for g(x) and f(x) the leading coefficients are of different signs. Meaning that f(x) opens upwards and g(x) opens downwards.
Hence, options 1,2 and three are correct answers.

Benny invests $960 yearly into an account that pays 8% interest, compounded
annually. Determine the amount in Benny's account after 10 years.
Answer:
$2,072.56
Step-by-step explanation:
Compound interest formula is expressed as;
A = P(1+r) ^ n
A = 960(1+0.08) ^ 10
A = 960(1.08)^10
A = 960(2.1589)
A = 2,072.56
Hence the amount in Benny's account after 10 years is $2,072.56
