Step-by-step explanation:
6 9 12 15:- multiplying by 3.
Answer:
B) 9
Step-by-step explanation:
When looking in both the horizontal and vertical direction of the missing space, we can see that the difference between the two numbers, 12 and 15, is 3.
15 - 12 = 3
Using this, we can see that each space on the second row and second column change by 3. Therefore, when looking at the missing space in the sequence, we can figure out that it is 9 by adding 3 to 6.

Describe two ways to determine the maximum or minimum of the quadratic function f(x)= -3x²+27x-42. Find the maximum or minimum using each method
Answers
Answer:
Find by using 1st derivative test (tests slope) or 2nd derivative test (test concavity). Maximum is 18.75.
Step-by-step explanation:
The maximum of the equation is found when the slope is 0; therefore, take the derivative of the equation, find the critical point and find whether the function is increasing or decreasing around the critical point. To do this use test values within the interval of (-∞, 4.5) and (4.5, ∞). You then find that (-∞, 4.5) is increasing meaning there is a maximum. Plug in 4.5 into f(x) to find the y value.
Second method is using the 2nd derivative test. Find the second derivative and use the same method of testing intervals but instead plugging in test values to the 2nd derivative. You then find that f''(x) is < 0 meaning the function is concave down, thus having a maximum. Plug in 4.5 to find the y value.

Answers
Answer:
D. 310.86 L
Step-by-step explanation:
[tex]\textsf{Volume of a cylinder}=\pi r^2h[/tex]
where:
[tex]r[/tex] is the radius[tex]h[/tex] is the heightGiven:
r = 0.3 mh = 1.1 m[tex]\pi[/tex] = 3.14[tex]\implies \sf \textsf{Volume of the tank}=(3.14)(0.3)^2(1.1)=0.31086\:m^3[/tex]
[tex]\sf 1\:liter = 1000\:cm^3[/tex]
To convert cubic cm to cubic meters, divide by 1,000,000:
[tex]\implies \sf 1\:liter =\dfrac{1000}{1,000,000} = 0.001\:m^3[/tex]
[tex]\implies \sf \textsf{Volume of the tank}=\dfrac{0.31086}{0.001}=310.86\:L[/tex]
The area of a rectangle is 46.56 mm2.
If the width is 9.7 mm, find the length.
Answers
Answer:
The length is 4.8 mm
Step-by-step explanation:
The area of a rectangle is calculated by multiplying the length times the width. So:
46.56 = l * w
46.56 = l * 9.7
To find the length, we must get "l" alone. To do this, we must divide both sides by 9.7.
46.56/9.7 = 4.8
4.8 = l
The length is 4.8

Answer:
[tex]113\° = \angle A[/tex]
Step-by-step explanation:
Given:
∠A = ∠B (Vertically opposite angles)∠A = 7x - 20∠B = 6x - 1If ∠A is equivalent to ∠B, then...
[tex]\implies 7x - 20 = 6x - 1[/tex]
Add 1 both sides:
[tex]\implies 7x - 20 + 1= 6x - 1 + 1[/tex]
Simplify both sides:
[tex]\implies 7x - 19= 6x[/tex]
Subtract 7x both sides:
[tex]\implies 7x- 7x - 19= 6x - 7x[/tex]
Simplify both sides:
[tex]\implies -19= -x[/tex]
Divide both sides by -1:
[tex]\implies \dfrac{-19}{-1} = \dfrac{-x}{-1}[/tex]
Simplify both sides:
[tex]\implies 19= x[/tex]
Substitute the value of x into "7x - 20" to determine ∠A:
[tex]\implies 7x - 20 = \angle A[/tex]
[tex]\implies 7(19) - 20 = \angle A[/tex]
Simplify the expression:
[tex]\implies 133 - 20 = \angle A[/tex]
[tex]\implies 113\° = \angle A[/tex]
Answer:
∠ A = 133
Step-by-step explanation:
Putting both angels together
Since,
m ∠ A = (7x-20)
m ∠ B = (6x-1)
Thus,
(7x-20) = (6x-1)
Solving for x:
7x - 20 = 6x -1
+20 +20
-------------------------
7x = 6x + 19
-6x -6x
-----------------------
1x = 19
x = 19
7(19) -20 = 113
6(19) - 1 = 113
Hence measure of m ∠ A = 113

Step-by-step explanation:
Peter's $12.00 is 30% of the total money all the brothers had.
$12.00 divided by 30% (.30) = $40.00

Answers
the top and the bottom have the same area, the sides have the same area, and the front and back have the same area
let’s find the sides first:
to find the area of the sides, multiple 19 and 7
19x7=133
since there’re two sides (the left and right), you have to multiply the 133 by 2
133x2=266
now, let’s do the top and bottom:
multiply 48 and 19, since those are the dimensions
48x19=912
multiply this also by two bc the top and the bottom have the same area
912x2=1824
lastly, let’s find the front and back
multiply 48 and 7 to get 336
multiply that again by 2 to get 672
now, add up the three numbers we just found:
266+1824+672=2762
the surface area should be 2762
hope this helped!!
Answer:
2762 in²
Step-by-step explanation:
The total surface area of a figure is the sum of the areas of its faces.
Area of rectangle= length ×breadth
Assuming that this is a closed box, the total surface area is the total area of its 6 rectangular faces.
Two rectangles have dimensions of 7 in. ×19 in., another two rectangles have dimensions of 48 in. ×7 in., and the last two rectangles have dimensions of 48 in. ×19 in.
Surface area of the figure
= 2(7)(19) +2(48)(7) +2(48)(19)
= 266 +672 +1824
= 2762 in²

The circumference of a circle is 15(pie) centimeters. what is the area Of the circle in terms of (pie)
Answers
Answer:
56.25π cm^2
Step-by-step explanation:
circumference = 15π
diameter*π = circumference
diameter = 15π/π
radius*2 = diameter
radius*2 = 15
radius = 7.5
area = π*radius^2
area = π*7.5^2
area = 56.25π
Answer:
A = 56.25π cm²
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius )
to find r use the circumference formula
C = 2πr
given C = 15π , then
2πr = 15π ( divide both sides by 2π )
r = 7.5 cm
then
A = π × 7.5² = 56.25π cm²

What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,
The inequality [tex]\sqrt{\dfrac12x^2-10}\geq 0[/tex]satisfied to find the domain of the function f(x).

The monthly payment of a loan for $3,000 at 7.5% interest compounded monthly for 36 months is $93.32.
loan amount P = $3000
Rate of interest = 7.5% per annum
So, monthly rate of interest r= 7.5/12 %
Tenure n = 36 months
What is the formula to calculate monthly payments?The formula to calculate monthly payments is given
[tex]EMI=\frac{Pr}{1-(r+1)^{-n} }[/tex]...........(1)
Where P =loan amount
r = monthly rate of interest
n=tenure
So by substituting the given values in (1) the monthly payment = $93.32
Hence, the monthly payment of a loan for $3,000 at 7.5% interest compounded monthly for 36 months is $93.32.
