Answer:
[tex]\frac{1}{3}[/tex] x³ + 5x + c
Step-by-step explanation:
Using the power rule
∫ a[tex]x^{n}[/tex] dx = [tex]\frac{a}{n+1}[/tex] [tex]x^{n+1}[/tex]
Thus
∫ x² + 5 dx

Which square root has a value between 13.8 and 14.5
A.190
B. 200
C. 213
D. 220
Answer:
B: 200
Step-by-step explanation:
The sqr of 200 is equal to 14.14. when plugged into the perimeters 13.8<x<14.5 , 14.14 satisfies the condition
The square root has a value between 13.8 and 14.5 is 200.
Option (B) is correct.
What is square root?A factor of a number that, when multiplied by itself, gives the original number. The square root of any number can be expressed using the formula: √y = y½.
Given:
The square root has a value between 13.8 and 14.5.
We have to find the square root has a value between 13.8 and 14.5.
According to given question we have
[tex]13.8 ^{2} =190.44\\\\14.5^{2} =210.25\\[/tex]
So, the square root has a value between 13.8 and 14.5 is 200.
when plugged into the perimeters 13.8<x<14.5.
Therefore, the square root has a value between 13.8 and 14.5 is 200.

Since, ABC is a triangle, we have:

[tex]a + 2a + C = 180[/tex]
[tex]3a + C = 180[/tex]
Subtract 3a from both sides

Given: KM bisects JKL
Prove: m MKL= 1/2m JKL
please explain
Start with out given statement:
Line KM bisects <JKL and the reason for that is because it's given.
For statement 2, we know that m<JKM = m<MKL
because of the definition of an angle bisector.
For statement 3, we can use the angle addition
postulate to get m<JKM + m<MKL = m<JKL.
For statement 4, we use substitution from
the info in statement 2 to get m<MKL + m<MKL = m<JKL.
For statement 5, we simplify to get 2(m < KML) = m<JKL.
For statement 5, we use the division property of equality.
All the reasons are underlined.

bring all the terms to one side and set equal to 0
[tex]x^2 - 12x + 32 = 0[/tex]
factor the polynomial

[tex](x-4)=0\\x-4 = 0\\x = 4[/tex]
Help!! 2(3x+4y)=4x+12y
Answer: x = 2y
Step-by-step explanation:
Let's solve for x.
2(3x+4y)=4x+12y
Step 1: Add -4x to both sides.
6x+8y+−4x=4x+12y+−4x
2x+8y=12y
Step 2: Add -8y to both sides.
2x+8y+−8y=12y+−8y
2x=4y
Step 3: Divide both sides by 2.
2x
2
=
4y
2
x=2y
Answer:
x=2y
Solve for x
2 ( 3x + 4y ) = 4x + 12y
6x + 8y = 4x + 12y
6x + 8y - 4x = 12y
2x + 8y = 12y
2x = 12y - 8y
2x = 4y
2x / 2 = 4y / 2
x = 4y / 2
x = 2y

Mr. Green wants to know how far he can run. He knows he can run 103,000 mm. How many miles can he run? Show all work if you want to receive credit.
I know the answer is 0.064 miles but I need the work!! help please
Answer:
1 Mile = 1609000 mm.
1.03 × 10^5 × 6.21371192237337 = 0.064 mile
103000 /1609344= 103000 mm.
Step-by-step explanation:
The beginning process is just to find the amount that mm = miles. After that you will move the decimal to then get 0.064 of a mile.
103,000 mm is 0.064 miles
So he can run 0.064 miles.
Given,
He can run = 103,000 mm
We need to find how many miles he can run.
How many mm in a mile?1 mile = 1609344 mm
Find how many miles is 103,000 mm.
We have,
1 mile = 1609344 mm
Multiplying both sides by 103,000
103,000 x 1 mile = 103,000 mm x 1609344
Divide both sides by 1609344
( 103,000 x 1 mile ) / 1609344 = (103,000 mm x 1609344) / 1609344
0.064 miles = 103,000 mm
This means 103,000 mm is 0.064 miles.
Thus 103,000 mm is 0.064 miles

Answer:
x = - [tex]\frac{7}{4}[/tex]
Step-by-step explanation:

20x + 12 = 4x - 16 ( subtract 4x from both sides )
16x + 12 = - 16 ( subtract 12 from both sides )
16x = - 28 ( divide both sides by 16 )

The actual distance between the library and train station is 500 ft. Explain how you
could find the distance between them in centimeters on the map.
Answer:
15,420 cm
Step-by-step explanation:
Given the actual distance between the library and train station to be 500 ft, to find the distance between them in centimeters, we ill convert 500 ft to cm as shown;
Given the conversion:
1 ft = 30.48cm
500ft = x cm
Cross multiply
x cm * 1ft= 30.48 cm * 500ft
x cm = 30.48 cm * 500ft/1ft
x cm = 15,240 cm
Hence the distance between them in centimeters on the map is 15,420 cm
