Answer:
D. G(x) = (x+3)² -2
Step-by-step explanation:
G(x) is translated left 3 and down 2 from F(x). The transformation ...
G(x) = F(x -h) +k
is a translation right h units and up k units. We have h=-3 and k=-2, so the function of interest is ...
G(x) = F(x +3) -2
G(x) = (x +3)² -2
The length of a rectangle is twice its width.
If the perimeter of the rectangle is 54 yd, find its length and width.
Answer:
Length 18 yds, Width 9 yds
Step-by-step explanation:
2x + 2x + x + x = 54
Combine like terms
6x = 54
Divide both sides by 6
x = 9
Plug 9 into equation above
2(9) + 2(9) + 9 + 9 =
18 + 18 + 18 = 54

7. Given directed line segment RT below, find the coordinates of S such that the ratio of RS to ST is 5:1. Plot point S
A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
The coordinate of S is: [tex](6,\frac{8}{3})[/tex]Given that:
[tex]RS : ST = 5 : 1[/tex]
The coordinates of RT are not given. So, I will solve using a general explanation.
When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:
[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
Assume the coordinate of R and T is:
[tex]R = (1,6)\\T = (7,2)[/tex]
[tex]RS : ST = 5 : 1[/tex] means:
[tex]m:n = 5:1[/tex]
So, point S is:
[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]
[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]
[tex]S = [6,\frac{8}{3}][/tex]
Hence, if the coordinates of R and T are:
[tex]R = (1,6)\\T = (7,2)[/tex]
And the line ratio is:
[tex]m:n = 5:1[/tex]
The coordinate of S is:
[tex]S = [6,\frac{8}{3}][/tex]

The expression two pi parentheses RH plus R to the power of two parentheses represents the total surface area of a cylinder with height H in radius R what is the surface area of the cylinder with a height of 6 cm and a radius 2 cm
Answer:
100.6cm2
Step-by-step explanation:
The mathematical expression wil become
[tex]2\pi(rh + {r}^{2} )[/tex]
The TSA of a cylinder is
[tex]2\pi \: rh + \pi {r}^{2} + \pi {r}^{2} [/tex]
When simplified, we have
[tex]2\pi \: rh + 2\pi {r}^{2} = 2\pi(rh + {r}^{2} )[/tex]
So indirectly, the expression is the same as total surface area of a cylinder.
So all you have to do is substitute the height and radius into any of the formulas .
[tex]2 \times \frac{22}{7} ( (2 \times 6) + {2}^{2} )[/tex]
[tex]2 \times \frac{22}{7} (12 + 4) \\ 2 \times \frac{22}{7} \times 16 \\ \frac{22 \times 2 \times 16}{7} \\ \frac{22 \times 32}{7} \\ \frac{704}{7} = 100.57 {cm}^{2} \\ = 100.6 {cm}^{2} [/tex]

Share £360 into the ratio 3:2:1
Answer:
£180, £120 and £60.
Step-by-step explanation:
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3*60 = 180
2*60 = 120
1 * 60 = 60.
The distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.
What is a ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3 x 60 = 180
2 x 60 = 120
1 x 60 = 60.
Hence the distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.

9514 1404 393
Answer:
= 0.108
Step-by-step explanation:
Use a calculator or long division.
When using long division, it is convenient to move the decimal points in both numbers to the right 2 places. This makes the divisor an integer, so makes it easier to keep track of appropriate place value in the quotient.
0.189/1.75 = 18.9/175 = 0.108
What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
9514 1404 393
Answer:
-4 1/8
Step-by-step explanation:
Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.
The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.
__
So, the problem can be rewritten as ...
-(1 7/8 +2 2/8)
= -((1+2) +(7/8 +2/8))
= -(3 +9/8)
The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...
-(3 +1 1/8) = -4 1/8
