Answer:-22
Step-by-step explanation:Just put the value -1 wherever there is x.
Answer:
f(-1) = -22
Step-by-step explanation:
f(x): 2x^3 - 3x^2 + 7x - 10
Repace x = -1
f(-1) = 2(-1)^3 - 3(-1)^2 + 7(-1) - 10
f(-1) = -2 - 3 - 7 - 10

How many factors of 10 are in 1000, only answer are three, two, four
Answers
Answer:
Step-by-step explanation:
The number 1000 has prime factors: 2, 2, 2, 5, 5, 5.
The factors of 1000 include 1 and combinations of these numbers multiplied together (in any arrangement):
1, 2*2*2*5*5*5 or 1, 1000
1*2, 2*2*5*5*5 or 2, 500
1*2*2, 2*5*5*5 or 4, 250
. . . (You already did these)
But, a “factor” is “a number or quantity that when multiplied with another produces a given number or expression,” so you should consider the following:
How many 1's? How many 5's? How Many 2's? [and any others ...]
1 = 1 0 0
2 = 1 0 1
4 = 1 0 2
8 = 1 0 3
5 = 1 1 0
10 = 1 1 1
20 = 1 1 2
40 = 1 1 3
25 = 1 2 0
50 = 1 2 1
100 = 1 2 2
200 = 1 2 3
125 = 1 3 0
250 = 1 3 1
500 = 1 3 2
1000 = 1 3 3

Step-by-step explanation:
Answer:
( x + 5 )² + ( y + 4 )² = 29
Step-by-step explanation:
Equation of the circle is

( h, k ) are coordinates of the center
~~~~~~~~~~~~~~~~~~~~~
Coordinates of the center of the circle are
( [tex]\frac{-3-7}{2}[/tex] , [tex]\frac{-9+1}{2}[/tex] ) = ( - 5 , - 4 )
d = 2√29 ⇒ r = √29

Complete Question
Hal says the volume of the sphere shown below is 36 cm³.Find the correct volume, using 3.14 for π. Round to the nearest hundredth. What was Hal's likely error? Use the drop-down menus to explain your answer.
Radius of the sphere = 3 cm
Answer:
a) The volume of the sphere = 113cm³
b) Hal's likely error was :
He used the wrong formula and did not make use of π = 3.14 in his calculation.
Step-by-step explanation:
a) The Volume of a Sphere = 4/3πr³
The radius of the sphere = 3cm
π = 3.14
The volume of the sphere = 4/3 × 3.14 × 3³
= 113.04 cm³
Approximately to the nearest hundredth = 113cm³.
b) Hal's likely error comes in two forms:
1) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)
ii) Also he did not use π in his calculation.
This means Hal's calculation=
Surface Area of a Sphere = 4πr²
But Hal's used = 4r²
Where r = 3cm = 4 × (3cm)²= 36 cm³

There is a prism with a pentagonal base the height is 8 cm the area of the pentagonal base is 30.5cm what is the volume of the prism
Answers
Answer:
244 cm³
Step-by-step explanation:
Step 1: Given data
Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
V = A × h
V = 30.5 cm² × 8 cm = 244 cm³

A report states that the mean household income last year for a certain rural county was $46,200 and the median was $54,500. If a histogram were constructed for the incomes of all households in the county, would you expect it to be skewed to the right, to the left, or approximately symmetric
Answers
Answer:
skewed to the left
Step-by-step explanation:
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.
If the mean is greater than the median, the histogram would be skewed to the right
If the mean is less than the median, the histogram would be skewed to the left.
The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left
The ratio of the number of laps Tonya swam last week to the number of laps Randy swam last week is 3:10. If Randy swam 84 MORE laps last week, how many did Tonya swim?
Answers
Answer:
The number of laps Tonya swam last week were:
36 laps.Step-by-step explanation:
To understand the ratio, you must know that 3:10 means that each time Tonya swam 3 laps, Randy swam 10 laps, by this reason, to identify the total number of laps you can divide the total difference given in the exercise (84 laps) into the difference indicated by the ratio (10 - 3 = 7 laps):
84 / 7 = 12This number obtained is the number of times the ratio had to be met so that the difference in laps swam was 84. Now, you must multiply the obtained value (12) by the number of laps from Tonya given in the ratio (3):
Tonya's total number of laps = 12 * 3Tonya's total number of laps = 36 lapsAs you can see, with the calculates, we obtained 36 laps in total. You could also do the iterations 12 times, subtracting the number of turns given by Tonya from the number of turns made by Randy and you would get the same result:
10 - 3 = 720 - 6 = 1430 - 9 = 2140 - 12 = 2850 - 15 = 3560 - 18 = 4270 - 21 = 4980 - 24 = 5690 - 27 = 63100 - 30 = 70110 - 33 = 77120 - 36 = 84Helloooo possess I need help as soon as possible

a(9)+0.48(8)17=30100
a(9)+0.48(8)a+0.48=30100
a(9)+0.48(8)17=30
Answers
Answer:
14 % pure juice comes from first brand
Step-by-step explanation:
Mixture:
17 gal 30% contains: 17x 30% = 5.10 gal pure juice
Second brand:
8 gal 48% contains: 8x40% = 3.84 gal pure juice
5.10 − 3.84 = 1.26 gal
1.26 gal is coming from 9 gal of first brand
The percentage of first brand is:
(1.26/9) x100 = 14 % pure juice.
