Answer:

5x^-2 is rewritten as a negative exponent

Restrictions are that 'a' and 'b' cannot be zero. We could write [tex]a \ne 0[/tex] and [tex]b \ne 0[/tex] as shorthand.

The restrictions are put in place to ensure that you can't divide by zero.

=========================================

Explanation:

The coefficients -12 and 4 divide to -12/4 = -3 which is the coefficient for the answer in the numerator.

The 'a' terms divide to (a^3)/(a^2) = a^(3-2) = a^1 = a. We subtract the exponents to simplify.

The b terms are handled in a similar manner to get (b^5)/(b^7) = b^(5-7) = b^(-2) = 1/(b^2)

Putting all three results together has us end up with (-3a)/(b^2) where neither 'a' nor b are zero to prevent a division by zero error. We cannot have 0 in the denominator.

perimeter = 8x+12

Step-by-step explanation:

perimeter of a rectangle = 2(Length + width)

= 2[(3x+5)+(x+1)]

=2( 3x+5+x+1)

=2(4x+6)

perimeter= 8x+12

Answer:

560x^3y^4.

Step-by-step explanation:

The (r+1)th term of (a + b)^r = nCr a^(n-r) b^r

We want the fifth term so r = 5 - 1 = 4:

(4 + 1)th term = 7C4 x^(7-4) (-2y)^4

= 35x^3 16y^4

= 560x^3y^4.

Answer:

Option A and Option D are correct

Hey There!!

The given equation is a circle with center = (0, 0) and radius = 4.

We compare the given equation with the standard form of a circle[tex](x-h)^2+(y-k)^2=r^2[/tex]

So, h = 0 , k = 0, [tex]r^2=16[/tex] or r = 4.

So the given equation is a circle with center = (0, 0) and radius = 4.

Answer:

Height of building is 115.86 m.

Step-by-step explanation:

This is problem of proportion.

a:b = c:d

____________________________________________________________

height of pole = 3.3 m

length of shadow of pole = 1.36 m

ratio

height of pole: length of shadow of pole = 3.3 : 1.36

________________________________________________

let the height of building= x m

length of shadow of building= 47.75 m

ratio

height of building: length of shadow of building= x: 47.75

ratio in both the cases will be same

thus,

x/47.75 = 3.3 / 1.36

=> x = 3.3 / 1.36 * 47.75 = 115.86

Thus, height of building is 115.86 m.

Answer:

All together she had a 18.1818182% raise but 18% raise rounded.

Step-by-step explanation:

First you need to find how much each stock increased.

So:

1700 to 2040

500 to 560

Add them.

1700 + 500 = 2200

2040 + 560 = 2600

Then find the raise. You can usally just find the amount for each percent or find the over all raise.

1% of 2200 is 22

400/22 = 18.18

Step-by-step explanation:

[tex]11m - (6m - 5) = 25\\[/tex]

Use - to open the bracket

[tex]-(6m-5)= -6m+5[/tex]

[tex]11m-6m+5=25\\[/tex]

Collect like terms and simplify

[tex]11m-6m=25-5\\5m = 20[/tex]

Divide both sides of the equation by 5

Answer:

x = -10, 10

Step-by-step explanation:

Step 1: Write out function

f(x) = 8x² - 800

Step 2: Set equal to 0

0 = 8x² - 800

Step 3: Add 800 on both sides

800 = 8x²

Step 4: Divide both sides by 8

x² = 100

Step 5: Take square root on both sides

x = ±10

Step 6: Arrange

-10 < 10

So x = -10, 10

Answer:

The slope of the line between points A and B is 0.25

Step-by-step explanation:

Here in this question, we simply aim at calculating the slope of the line between two given points;

The points in question are;

A(400,40) and B(480,60)

Mathematically, the slope of the line can be calculated using the formula:

slope = (y2-y1)/(x2-x1)

Where ;

x1 = 400

y1 = 40

x2 = 480

y2 = 60

Substituting the values, we have;

slope = (60-40)/(480-400) = 20/80 = 1/4 = 0.25

the line is vertical

Answer:

13y - 55

Step-by-step explanation:

Given

7(3y - 5) - 2(10 + 4y) ← distribute both parenthesis

= 21y - 35 - 20 - 8y ← collect like terms

= 13y - 55

Answer:

When using the distributive property, we can operate parenthesis:

[tex]a*(b+c)=ab + ac[/tex]

So, in our case:

[tex]7(3y-5) -2(10+4y)[/tex]

[tex]7*3y+7*(-5) - 2*10-2*4y[/tex]

[tex]21y -35 - 20 - 8y[/tex]

[tex]=13y - 55[/tex]

So now we know the result is 13y - 55

Answer:

Step-by-step explanation:

A triangle consists of 3 angles and sides. The sum of the angles in a triangle is 180°. Let the angle be <A, <B and <C.

<A + <B + <C = 180° ...... 1

If the measure of one angle is twice the measure of a second angle then

<A = 2<B ...... 2

Also if the third angle measures 3 times the second angle decreased by 48, this is expressed as <C = 3<B-48............ 3

Substituting equations 2 and 3 into 1 will give;

(2<B) + <B + (3<B-48) = 180°

6<B- 48 = 180°

add 48 to both sides

6<B-48+48 = 180+48

6<B = 228

<B = 228/6

<B =38°

To get the other angles of the triangle;

Since <A = 2<B  from equation 2;

<A = 2(38)

<A = 76°

Also <C = 3<B-48 from equation 3;

<C = 3(38)-48

<C = 114-48

<C = 66°

Hence the measures of the angles of the triangle are 38°, 66° and 76°
