Do I always simplify a question before doing the operations? For example, do I always simplify a fraction before doing the operations?
For example for this question:
(8-4√2) /2 + ( 6+4√2)/ 2

I had to simplify the fraction by factoring, cancelling and then do the operation or I got it wrong.

Step-by-step explanation:

Answer:

hey I believe standard form would look like this:  f(x) = a(x - h)^2 + k

this is regular form f(x)=ax^2+bx+c or something like x^2+4x+4.

I think H and K are the vertex

Answer:

6 inch

Step-by-step explanation:

half the diameter to find the length

The outer edge length of one piece of the cut circle is  3π / 2 inches

The diameter of a circle is a line that passes through the centre and meets the circumference at opposite ends.

The circle representing the pizza is 12 inches in diameter. The radius is half of the diameter. Therefore,

radius = 12 × 0.5 = 6 inches

The circle is cut into 8 congruent pieces. The length of the outer edges of any one piece of the circle can be calculated as follows;

circumference of the circle = 2πr

circumference of the circle = 2 × π × 6 = 12π inches

Now let's divide it into 8 part.

edge length of one piece of the circle = 12π / 8 = 3π / 2

Answer:

There is no x in the second equation

Answer:

d) 0 with multiplicity 3 , -3 with multiplicity 1 and - 6 with multiplicity 1

Step-by-step explanation:

Explanation:-

Given  polynomial equation  

                   ⇒        - x⁵ + 9 x⁴ - 18 x³

                    ⇒     - x³ ( x² - 9 x + 18 )

                    ⇒    - x³ ( x² - 6 x  - 3 x + 18)

                    ⇒    - x³ ( x(x -  6)  - 3( x - 6))

                   ⇒     - (x-0)³ (x-6)(x-3)

∴ The Zeros of the given function is 0 with multiplicity 3 , -3 with multiplicity 1 and - 6 with multiplicity 1

Answer:

(10, 2)

Step-by-step explanation:

To get from the given endpoint to the midpoint, 6 was added to x and 2 was added to y. As per the definition of a midpoint, the resulting two line segments will be congruent (first endpoint and midpoint congruent to midpoint and second endpoint). Use the same formula (x + 6, y + 2) to find the second endpoint (use the x and y of the midpoint):

(x + 6, y + 2)

Endpoint  ( 10, 2)

Answer:

21

Step-by-step explanation:

Equation of the given line y = 15x + b.

Points passing through the above line (6.4, 117) and (6.6, 120)

If these point pass through the given line.

These point should satisfy the equation.

plugging in value of one of the point (6.4, 117)  in the line y = 15x + b

we have

117 = 15*6.4 + b

=> 117 = 96 + b

=> 117 - 96 = b

=> b = 21

Thus, value of b in the given equation is 21.

Answer:

21

Step-by-step explanation:

When x = 6.4, y=117, therefore

15*6.4 + b = 117

b = 117 -  96 = 21

A is TRUE (44 in²*2=88 in²)

B is FALSE x(x-3)=88 (the rectangle) or x(x-3)/2=44 (the triangle)

D is TRUE :

x²-3x-88=0

Answer:

Part A: yes . Part B: minus 24

Step-by-step explanation:

Part A

8x + 8 = 56

8x = 56-8

8x = 48

x = 48 / 8

x = 6 , YES!

Part B

Suppose x = 9 and find y:

8(9) + 8 + y = 56

80 + y = 56

y = 56 - 80

y = -24

So we have to add -24 to the equation. The new equation: 8x + 8 - 24 = 56

It will take almost 6 years to depreciate the value of the car to 10100 dollars.

Depreciation is a term used to indicate the decreasing value of an asset over time due to use, unfavorable market conditions and so on.

Initial amount of the car = 15700 dollars

Depreciating percent = 7.5% = 7.5/100 = 0.075

Final amount = 10100 dollars

Number of years taken to depreciate the value of the car to 10100 dollars can be found by the formula,

A = P(1 + r)ⁿ

where A = 10100 dollars, P = 15700 dollars, r = -0.075.

10100 = 15700 (1 - 0.075)ⁿ

10100 / 15700 = (1 - 0.075)ⁿ

0.6433 = (0.925)ⁿ

Taking logarithm on both sides,

㏒ 0.6433 = ㏒ (0.925)ⁿ

We have the power rule for logarithms, ㏒ (mⁿ) = n ㏒(m)

㏒ 0.6433 = n ㏒ (0.925)

n = ㏒ 0.6433 / ㏒ (0.925)

n = 5.658 ≈ 6 years

Hence almost 6 years will be taken to depreciate the value of the car to 10100 dollars.

Step-by-step explanation:

Measure of spread is used in describing the variability in a sample.

Examples of measure of spread are: Mean, Median and Mode.

A measure of spread helps in giving an idea of how well the mean, or mode, or median, whichever of the three measure of spreads we use, represents the data under consideration. If the spread of values in the data set is large, that means there a lot of variation between the values of the data set. It is always better to have a small spread.

Answer:

Measuring the spread of a data set tells us how far are the values of data set to respect the mean. For example, large mean absolute deviation (MAD) value indicates that the values of data set are very different from the mean, i. e., they are very spread. Therefore, the mean is not representative of the data. On the other hand, in a small spread case, the mean is representative.

Answer:

V= 840cm^3,   V=800cm^3

Step-by-step explanation:

First you want to calculate the volume of the entire imaginary prism, 12×15×6

=1080,

afterwards you want to calculate the missing volume, which you can think of as a bite. First, find the sides.

12-8=4            5-15=10

Now calculate the volume of the bite, 4×10×6

=240

Now take the bite out of the sandwich, 1080-240

= 840

Follow the same steps, though this time the sides of the "bite" are given.

10×12×8

= 960

4×5×8

= 160

960-160 = 800 cm

Answer:

Area = 36 sq. units

Step-by-step explanation:

The 3 values you need to solve for the area are the top base length, bottom base length, and height.

Top base length = 7 . It's the distance between point A and B.

Bottom base length = 11. It's the distance between points C and D.

Height = 4. It's the perpendicular distance from the top to the bottom base.

The formula to solve the area of a trapezoid (or trapezium, I'm American) is:

A = [tex]\frac{1}{2}h(b_{1} +b_{2})[/tex]

Put in the numbers above for the unknowns and you will get this:

A = [tex]\frac{1}{2}(4)(7 + 11)[/tex]

Simplify:

A= [tex]\frac{1}{2}(4)(18)[/tex]

A = 2(18)

A = 36

So the answer is 36. Hope I helped!

Answer:

36

Step-by-step explanation:

top base= B(x)-A(x)= 10-3= 7

bottom base= C(x)- D(x)= 12-1= 11

height= A(y) - D(y) = B(y)- C(y)= 5-1=4

Area= 1/2(7+11)*4= 36
