Answer:
[tex]12^{2}[/tex]
Step-by-step explanation:
To find: a power that has a value greater than 140 and less than 145
Solution:
Take [tex]x=12^{2}[/tex]
Here,
[tex]12^{2}=144[/tex] and [tex]140<144<145[/tex]
That is [tex]140<x<145[/tex]
Therefore,
[tex]12^{2}[/tex] has a value greater than 140 and less than 145.

You are told that a third powered polynomial has zeroes at -1, 2, 5.
Part A. Write the three factors of the polynomial
Part B. Write the polynomial in standard form
Answer:
a) factors of polynomial are: (x+1)(x-2)(x-5)
b) the required polynomial in standard form is: [tex]\mathbf{x^3-6x^2+3x+10}[/tex]
Step-by-step explanation:
The polynomial has zeros at -1,2,5
Part A) Write the three factors of the polynomial
we have x=-1, x=2 and x=5 as zeros of polynomial
so factors will be:
(x+1)=0, (x-2)=0, (x-5)=0
So, factors of polynomial are: (x+1)(x-2)(x-5)
Part B) Write the polynomial in standard form
For finding polynomial, we will multiply all the factors i.e
(x+1)(x-2)(x-5)
[tex](x+1)(x-2)(x-5)\\=(x(x-2)+1(x-2))(x-5)\\=(x^2-2x+x-2)(x-5)\\=(x^2-x-2)(x-5)\\=x(x^2-x-2)-5(x^2-x-2)\\=x^3-x^2-2x-5x^2+5x+10\\=x^3-x^2-5x^2+5x-2x+10\\=x^3-6x^2+3x+10[/tex]
So, the required polynomial in standard form is: [tex]x^3-6x^2+3x+10[/tex]
What is the approximate area of the circle shown below? (The radius is 21cm)
A. 1385 cm2
B. 66 cm2
C. 5540 cm2
D. 132 cm
Answer:
The answer is A. 1385 cm2
Step-by-step explanation:
Use the formula A = pi times radius squared
Answer:
A. 1385 cm²
Step-by-step explanation:
Area of a circle is πr²
We know what the radius is, so all we have to do is plug it in.
π(21)²
π(21)²= 1385.44
Since it's approximate, it would just be 1385 cm²

Answer:
- 7x - 10y
Step-by-step explanation:
You add the “like” terms.
x - y - 8x - 9y
x - 8x And - y - 9y
-7x - 10y
Answer:
-7x-10y
Step-by-step explanation:
1. Combine like terms
= x+−y+−8x+−9y
= (x+−8x)+(−y+−9y)
= −7x+−10y
Explain what the vertical intercept represents in this situation.
Answer:
In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. The value of c is called the vertical intercept of the line. It is the value of y when x = 0. When drawing a line, c gives the position where the line cuts the vertical axis.

Two sisters have decided to watch all the episodes of a popular TV show on DVD. Annie has already watched 4 episodes and will continue to watch the show at a rate of 1 episode per day. Abby, who hasn't yet seen the show, will start watching 3 episodes per day. Once the two sisters get to the point where they have watched the same number of episodes, they plan to finish the series together. How long will that take?
Answer:
2 days
Step-by-step explanation:
Assume that Annie and Abby watched the same number of episodes in [tex]t[/tex] days.
Number of episodes watched by Annie [tex]=4+1(t)=4+t[/tex]
Number of episodes watched by Abby [tex]=3t[/tex]
[tex]4+t=3t\\4=3t-t\\4=2t\\t=2[/tex]
So,
Annie and Abby watched the same number of episodes in [tex]2[/tex] days

What is 51% of 200 in steps?
Answer:
51% of 200 =
102
Step-by-step explanation:
51 x 200 = 10200
100 1 = 100 10200/100 = 102
percentages is out of 100
Another way:
51/100 is .51 so just multiply it by 200!
.51 x 200 = 102
Hope this helps you out! :)
Answer:
102 StepsStep-by-step explanation:
How you get 51% of 200 is by multiplying 51 by 200 then dividing the value of 51 times 200 by 100.
51 ⋅ 200 = 10200 ÷ 100 = 102 Steps
So, 51% of 200 equals 102 Steps

A running back on the high school football team was tackled for a 10-yard loss. On the very next play, the running back gains 10 yards. How many yards does the running back have after these two plays? Please hellpppp
Answer:
He has 0 yards
Step-by-step explanation:
Initially he lost 10 yards
This means that he is 10 yards away from the starting point which we shall call origin
Afterwards, he gained 10 yards
what this mean is that he is back at the original point before the loss
Since he gained what he lost, then he is back at the origin and then we can say that no yards was lost or gain so we have him gaining 0 yards only

Which pair of events are independent of each other?
A.
selecting an ace from a deck of cards, and then drawing another ace without replacing the first
B.
drawing a red paperclip from a bag of paperclips, and then drawing another red paperclip without replacing the first
C.
drawing a ball from a bag, and then drawing another ball without replacing the first
D.
getting an even number on the first and second roll of the die
PLZ EXPLAIN
Answer:
D
Step-by-step explanation:
Rolling a die and getting a certain number will not change the chances of you getting the same number a second time. A normal die will always have a 1/2 chance of rolling an even number. However, the other answer choices will make the likelihood of getting the same type of event again slimmer as you remove one of the objects from being chosen again. An example for the first option would be drawing an ace from a deck of 52 cards where you only have 4 aces, so the chance on the first draw would have been 4/52 or a 7.7% chance while the next draw will be a 3/51 or 5.9% chance.

At work, greg makes $14 for every hour that he works. Write a function to represent how many dollars, D, greg has entered from working, then calculate how much money he made after working 5 hours
Answer:
[tex]D(h) = 14 h[/tex]
He made $70 in 5 hours
Step-by-step explanation:
Given
[tex]Hourly\ Rate = \$14[/tex]
Required
Determine a function to represent the amount he made
Determine the amount made in 5 hours
To determine the function (D), we simply multiply the hourly rate by the number of hours worked (h).
So, we have:
[tex]D = Hourly\ Rate * h[/tex]
[tex]D = 14 * h[/tex]
[tex]D = 14 h[/tex]
Represent D as a function
[tex]D(h) = 14 h[/tex]
Solving (b): Amount in 5 hours
We have that
[tex]D(h) = 14 h[/tex]
In this case:
[tex]h = 5[/tex]
So, we have:
[tex]D(5) = 14 * 5[/tex]
[tex]D(5) = 70[/tex]
Hence, he made $70 in 5 hours

If the system given has parallel lines, what is the answer?
We need to see the "given system".
Answer:
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.
