find the real zeros of k(x)= x^3 - 2x^2 +2x -4

Answer:

Find the area by multiplying the base by the height. From the problem, the length (base) of the rectangle is 5 units. The height of the rectangle is

[tex]3\frac{1}{2} [/tex]

inches. Multiply to find the area.

[tex]5 \times 3 \frac{1}{2} = 17 \frac{1}{2} [/tex]

The area of the rectangle is 17 1/2 units squared. The answer you provided is correct!

Answer: He has 8 dimes

Step-by-step explanation:

Answer:

17 dimes

7 nickels

Step-by-step explanation:

n = number of nickels

d = number of dimes

0.10d + 0.05n = 2.05

n + d = 24, n = 24 - d

substitute for n:

0.10d + 0.05(24 - d) = 2.05

simplify:

0.10d + 1.20 - 0.05d = 2.05

0.05d = 0.85

d = 17

n = 24-17 = 7

Answer:

Step-by-step explanation:

the formula for the circumference of a circle is 2rπ

the formula for the area of a circle is (r^2)π

the formula for the diameter of a circle is 2r

π=3.14

---------------------------------------------------------------

1. diameter =2r.    since diameter=24, r=12

2. circumference=2rπ.     since circumference = 314.     314=2rπ       r=49.9746

3. circumference=2rπ                                           area=(r^2)π

   since r=7, circumference=14π=43.98229      since r=7, area is 49π=153.9380

4. Since the diameter is 20 the radius is 10. so just insert it into the formulas as before:    circumference=20π=62.8318 and area=100π=314.15926

5.  the formula for the diameter is 2r=d        2(18)=d,    36=d

6. 2rπ=circumference = 2(5)π=10π=31.415926

Hope that helps :)

Step-by-step explanation:

y = -5/4 - 3r/8

r = -10/3 - 8y/3

I hoped this help plsssss mark me as brainlist if it does that would mean alot and i took lots of . time in this thank you!

Answer:

y = -7

Step-by-step explanation:

5x+8y=29

5(17)+8y=29 (simplify by multiplying)

85+8y=29 (subtract 85 from both sides)

8y= -56 (divide both sides by 8y)

y = -7

Answer:

n = 75(2)^d

Step-by-step explanation:

Mathematically, we have the general form of an exponential equation as follows;

y = I(1 + r)^x

where I is the initial value

r is the rate percentage

x is the number of time

From the question, the bacteria population doubles

This mean it increases by 100%

100% = 1

add this to the initial 1, and we have 2

Replace I with the number 75

And d represents the days

so we have;

n = 75(2)^d

Answer:

Yes, they are equivalent

Step-by-step explanation:

15 months= 1.25 years

60/2.5= 24

30/1.25 = 24

Answer:

Step-by-step explanation:

Since 2.5 years equals 2.5(12)=30months you have

60cm/30mo and 30cm/15mo these are equivalent because (2/2)(30/15)=60/30

Answer:

A2 = 120

A3 = 60

A5 = 60

A6 = 120

Step-by-step explanation:

Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.

Angle 1 and 3 are vertical angles, which are always the same measure.

Angle 5 is alternate interior angles with 3, which means it is also 60.

Angle 6 is alternate interior angles with 4, which means it is 120.

Answer:

Im pretty sure its 114 m^2 sorry if im wrong

Answer:

The total surface area of the figure would be 114m.

Given:

The phrase is "six times a number is less than negative thirty-nine and three-quarters".

To find:

The inequality represented by the given phrase.

Solution:

Let x be the unknown number.

Six times a number is "6x".

Less than is "<".

Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".

So, six times a number is less than negative thirty-nine and three-quarters is:

[tex]6x<-39\dfrac{3}{4}[/tex]

Therefore, the correct option is C.

Answer:

"six times a number is less than negative thirty-nine and three-quarters".

Step-by-step explanation:

or C

Answer: 2.05 pints

Step-by-step explanation:

Shiva used 8.2 pints in total to paint the bedroom.

3/4 of this was blue paint which means that the remaining 1/4 is white paint.

Pints of white paint used:

= Proportion of white paint * Total pints used

= 1/4 * 8.2

= 2.05 pints
