Between what two consecutive integers would the square root of 40 fall?
A. 5 and 6
B 6 and 7
C 7 and 8
D 36 and 49
[tex]\sqrt{40}=\sqrt{2\cdot2^2\cdot5}=2\sqrt{10}[/tex]
Notice that [tex]\sqrt{10}\approx3.2[/tex] which means [tex]\sqrt{40}\approx2\cdot3.2\approx6.4[/tex].
So answer is B.

B. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 47, 49, 48, 47.
C. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 45, 45, 43, 41.

Write the repeating decimal as a fraction.
0.928
To convert the decimal 0.928 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.928 = 0.928
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,
0.928
1
= (0.928 × 1000)
(1 × 1000)
= 928
1000
.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(928,1000) = 8. So,
(928÷8)
(1000÷8)
= 116
125
when reduced to the simplest form.

suppose the velocity of a particle traveling along the x-axis is given by v(t)= 3t^2+8t+15 m/s at time t seconds. The particle is initially located 5 meters left of the origin. How far does the particle travel from t=2 seconds to t=3 seconds? After 3 seconds, where is the particle with respect to the origin?
Answer:
Step-by-step explanation:
1) How far does the particle travel from t=2 seconds to t=3 seconds?
[tex]\int\limits^3_2 {(3t^2+8t+15)} \, dt =\Bigg [ t^3+4t^2+15t\Bigg]^3_2\\\\=27+36+45-(8+16+30)\\\\=108-54\\\\=54 (m)\\\\[/tex]
2)
[tex]\int\limits^3_0 {(3t^2+8t+15)} \, dt =\Bigg [ t^3+4t^2+15t\Bigg]^3_2=108\\\\[/tex]
After 3 seconds, where is the particle with respect to the origin?
108-5=103 (m)

The pH level, P, of a liquid can be determined from the hydronium ion (H3O+) concentration, c, using the equation P = –log(c). If the pH level of grape juice is 3.3, what is the hydronium ion concentration
The equation [tex]P = -\log(c)[/tex] is an illustration of logarithms. The hydronium ion concentration is approximately [tex]0.0005012[/tex]
Given that:
[tex]P = -\log(c)[/tex]
When the pH level is 3.3; it means that:
[tex]P = 3.3[/tex]
So, we have:
[tex]3.3 = -\log(c)[/tex]
Divide both sides by -1
[tex]-3.3 = \log(c)[/tex]
Take antilog of both sides
[tex]10^{-3.3} = c[/tex]
So, we have:
[tex]c = 10^{-3.3}[/tex]
[tex]c = 0.00050118723[/tex]
Approximate
[tex]c = 0.0005012[/tex]
Hence, the hydronium ion concentration is approximately [tex]0.0005012[/tex]

what is some work for 34.1 divided by 5.5
Answer:
6.2
Step-by-step explanation:
The first step is to write the question out as you would normally, to divide two whole numbers.
5.5⟌34.1 (the bar should go all the way across but I can't do that here)
06.2
5.5⟌34.1
-33
11
5.5 does not go into 3, so we move over a place and see how many times it goes into 34.
6x5.5 is 33, so that's close enough.
We subtract 33 from 34 to get 1, and then bring the decimal point up to the answer.
11/5.5 is 2, but it's actually .2 because we brought the decimal point up.
Find a if the two polynomials ax³ + 3x² - 9 and 2x³ + 4x + 9, leaves the same remainder when divided by x + 3
Answer:
a = 25/9
Step-by-step explanation:
the remainder when divided by x+3 is just f(-3) so, we have

Write the equation of the line that
Passes through (-9,4) and 10,-2)
Answer:
y = -6/19x - 2
Step-by-step explanation:
First we need to find the slope and we can do that by using slope-intercept form [ y2-y1/x2-x1 ].
-2-4/10-(-9)
-6/19
Second we can find the y-intercept using slope intercept form [ y = mx + b], the slope, and a given point.
y = -6/19x + b
4 = -6/19(-9) + b
4 = 54/19 + b
-2 = b
Third we will input all the data we solved for back into the formula.
y = -6/19x - 2

3X-4(2X+1)=5 + 2(3X-1)
Answer:
x = -7/11
Step-by-step explanation:
3x - 4(2x + 1) = 5 + 2(3x - 1)
3x - 8x - 4 = 5 + 6x - 2
-5x - 4 = 3 + 6x
-5x - 4 + 5x = 3 + 6x + 5x
-4 = 3 + 11x
-4 - 3 = 3 + 11x - 3
-7 = 11x
-7/11 = 11x/11
-7/11 = x
-4x+3x=2

Write 2 1/4 miles in 3/4 hour as a unit rate.
6 3/4 per hour or, in an hour
2 1/4 miles in 3/4 of an hour
2 1/4 miles = 9/4 miles in 1/3 of hour
9/4 miles divided by 1/3 hr
9/4 ÷ 1/3
Remember: Keep, Change Flip
9/4 x 3/1 = 27/4
Simplify:
27/4 = 6 3/4
So,
6 3/4 in one hour
