What is the area of the figure shown below?

A) 22 yd sq
B) 26 yd sq
C) 43 yd sq
D) 49 yd sq

Answer:

1.25 × 10^-4

Step-by-step explanation:

Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4

Answer:Simple interest is money earned on a savings account or an investment. ... 45. Multiply. The interest earned is $45 after 3 years. b. To find the balance, add the interest to ... 2. You put $1000 in an account. The account earns $100 simple interest ... of $10,000 to earn $750 interest? ... interest earned on $200 after 8 months.

Answer:

2(x+1)(3x+1)

Step-by-step explanation:

(2x+2)(3x+1)

Apply the distributive property by multiplying each term of 2x+2 by each term of 3x+1.

6x^2+2x+6x+2

Combine 2x and 6x to get 8x.

6x^2+8x+2

Answer:

6x²+8x+2

Step-by-step explanation:

multiply each ferm in the first set of parenthess by each term in the second parentheses (FOIL)

2x times 3x +2x+ 2x times 3x+2

6x+2x+2 times 3x +2

6x²+2x+6x+2

now collect like terms

6x²+8x+2

Answer:

a=  

⇒ 3.5

b=  

⇒ 1.5

c=  

⇒ -1.5

d=  

⇒ 6.5

e=  

⇒ 1.5 f=  

⇒ -2.5

g=  

⇒ -8.5

h=  

⇒ -2.5

i=  

⇒ 3.5

Step-by-step explanation:

The values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.

It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.

We have a matrix A shown in the picture:

         | 2   3   3 |

A =    | 3    1   2 |

         | 7    8   9 |

It is required to find the inverses of a matrix.

To find the inverse of a matrix:

Augment with a 3x3 identity matrix

[tex]=\begin{bmatrix}2&3&3&\mid \:&1&0&0\\ 3&1&2&\mid \:&0&1&0\\ 7&8&9&\mid \:&0&0&1\end{bmatrix}[/tex]

Convert the matrix to the identity matrix.

[tex]=\begin{bmatrix}1&0&0&\mid \:&\frac{7}{2}&\frac{3}{2}&-\frac{3}{2}\\ 0&1&0&\mid \:&\frac{13}{2}&\frac{3}{2}&-\frac{5}{2}\\ 0&0&1&\mid \:&-\frac{17}{2}&-\frac{5}{2}&\frac{7}{2}\end{bmatrix}[/tex]

Simply it:

[tex]=\begin{pmatrix}\dfrac{7}{2}&\dfrac{3}{2}&-\dfrac{3}{2}\\ \dfrac{13}{2}&\dfrac{3}{2}&-\dfrac{5}{2}\\ -\dfrac{17}{2}&-\dfrac{5}{2}&\dfrac{7}{2}\end{pmatrix}[/tex]

From the inverse matrix the values of unknows can be find:

a = 7/2

b = 3/2

c = -3/2

d = 13/2

e = 3/2

f = -5/2

g = -17/2

h = -5/2

i = 7/2

Thus, the values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.

Answer:

R=5%/year

Step-by-step explanation:

R = 5%/year

Equation:

r = I / Pt

Calculation:

Solving our equation

r = 1400 / ( 7000 × 4 ) = 0.05

r = 0.05

converting r decimal to a percentage

R = 0.05 * 100 = 5%/year

The interest rate required to

accumulate simple interest of $ 1,400.00

from a principal of $ 7,000.00

over 4 years is 5% per year.

Answer:

A- the graph of f(x) is shifted 7 units down

Step-by-step explanation:

Answer:

There is a similar problem with the same numbers except with no negatives so it goes 1 , 3 , 9 , 27, 81 for this question the answer is that it diverges.

Step-by-step explanation:

It was on the unit test review for edge and the answer was that it diverges.

This is about  understanding the behavior limits of sequence.

The sequence diverges.

1, –3, 9, –27, 81,...

• Thus, the sequence is a divergent one.

Answer:

x=18

Step-by-step explanation:

Let look at the triangle. Look at side JUI. Notices how it says JU is congruent to UI. By this definition, U must be the midpoint of J and I. The same applies for line JTK. T is the midpoint of J and K. Since J is the vertex of the triangle between K and I. Triangle JUT is the midsegment of triangle KJI. Using the triangle midsegment theorem, UT is parallel to KI Also. The theorem also states that UT is half the length of KI Also.

This is the theorem,

The Midsegment Theorem states that the segment connecting the midpoints of two sides of a triangle is parallel to the third side and half as long

So the equation is

[tex]2(3x - 43) = 4 + x[/tex]

[tex]6x - 86 = 4 + x[/tex]

[tex]5x - 86 = 4[/tex]

[tex]5x = 90[/tex]

[tex]x = 18[/tex]

Answer:

d)

Step-by-step explanation:

turn 9x + y = 8 to slope intercept form

9x + y = 8

Answer:

21.42ft

Step-by-step explanation:

a²+b²=c² where "c" is the hypotenuse of a right triangle and "a" and "b" are the two other sides

now let's plug in the values

21²+b²=30²

b²= 30² - 21²

b²= 459

b= 21.42

Answer:

15 dollars

Step-by-step explanation:

Store W charges 5 dollars for unlimited copies, so the number of copies does not matter for store W.

Because store W offers unlimited copies for $5, that will be the amount that store Z has to charge to be the same amount.

Now, we know that store Z charges you 2 dollars at the start for the use of the machine, so you subtract from the total amount from store W, 5 dollars.

5-2=3

So now you have 3 dollars to pay for the copies from store Z.

Each copy from store Z costs $.20.

Answer:

t=7

Step-by-step explanation:

N=45

find t

45=t^2-t/2

0=t^2-t/2-45

use the quadratic formula

Answer:

∠Y = 55°

Step-by-step explanation:

Since triangle ABC and XYZ are congruent, that means that...

∠A = ∠X

∠B = ∠Y

∠C = ∠Z

Since ∠Y = ∠B and ∠B = 55°, that means ∠Y = 55°.

Answer:

Step-by-step explanation:

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4
