Which expressions have a value of 49 when w = 4? Choose the correct answers and show your work.

A) 3w2+ 25

B) 7(w2- 9)

C) w3/8+ 41

The equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]

The equation of a circle is [tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex] where r is the radius and (h,k) is the center of a circle.

The radius of a circle is 5.

Also, the center of a circle is (h,k) = (6,-2)

So, the equation of a circle is [tex](x-6)^{2}+(y-(-2))^{2} =5^{2}[/tex]

Simplify further the above equation.

[tex](x-6)^{2}+(y+2)^{2} =25[/tex]

Thus, the equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]

Hence, option (D) is correct.

Answer: -4

Step-by-step explanation:

Answer:

We have the answer as:

P'(0, 13), O'(-9, 13), R'(-3, 16)

Step-by-step explanation:

Here, we want to find the coordinates of the image after applying the transformation rule to the pre-image

what the transformation rule is saying is that we subtract 3 from the x-coordinate and add 7 to the y-coordinate

mathematically, we have these as follows;

P’ = (3-3, 6 + 7) = (0,13)

Q’ = (-6-3, 6 + 7) = (-9,13)

R’ ( 0-3, 9 + 7) = (-3, 16)

The product of -1/6 x -3/5 = 1/10

The given expression is,

-1/6 x -3/5

In mathematics, a fraction is defined as a portion of the total. If a pizza is cut into four equal pieces, each slice is represented by 14. Fractions make it easier to distribute and assess numbers and speed up calculations. The depiction of fractions appears easier without the use of decimal values.

Now proceed the product,

Multiply numerator with numerator and denominator with denominator,

Therefore,

-1/6 x -3/5 = -1x(-3)/6x5

                = 3/30

                = 1/10

Hence,

-1/6 x -3/5 = 1/10

Answer:

Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.

Width = A

Length = B

Diagonal = C

so: a2+b2=c

2502+1002=c2

2500+10000=c2

12500=c2

c=√12500

c=111.80 yards

Answer:

819

Step-by-step explanation:

We solve the above question using simple interest

The formula for the total amount in a bank amount when it earn simple interest annually is:

A = P(1 + rt)

When

P = Initial amount in the account = 780

r = Simple Interest rate = 2.5% = 0.025

t = 2 years

A = 780(1 + 0.025 × 2)

A = 780(1 + 0.050)

A = 780(1 .050)

A = 819.00

The amount of money that will be in her account if she does not make any deposits or withdrawals in 2 years is 819.

Answer:

x = 4.5 AND x = -4

Step-by-step explanation:

for the first answer

add 9 to 0 and divide by 2

for the second answer

subtract 4

Answer:

x = 9/2 and x = -4

Step-by-step explanation:

you can set each expression in the parenthesis' equal to zero. this is due to it being multiplication so if one parenthesis equals 0, the answer will be 0

2x - 9 = 0 and x + 4 = 0

starting with 2x-9=0

add 9 to both sides

2x = 9

divide by 2

x = 9/2

then do x + 4 = 0

subtract 4

x = -4

so your two answers are

x = 9/2 and x = -4

Answer:

I think the first option is better.

Step-by-step explanation:

First : 5.75% of $5000 is 287.5. 287.5 * 24 = 6900

And 6.55 of $5000 is 325. 325 * 36 = 117000

If she takes the first option it would be better because it is nearer to what she can afford. It is also better because it helps her make more than 5000 in less time.
