Answer:
D. aₙ = 5n - 11Step-by-step explanation:
The equation of the nth term of the arithmetic sequence is: [tex]a_n =a_1+d(n-1)[/tex]
d = 9 - 4 = 5
a₁ = -6
Therefore:
[tex]a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11[/tex]

If the radius of a circle is 44 cm, then what is the diameter?
A 44 cm
B 88 cm
C 22 cm
D 1 cm
Step-by-step explanation:
[tex]44 \times 2 = 88[/tex]
Answer:
B, 88 cm
Step-by-step explanation:
Remember, the radius is half the diameter, so if you know the radius, all you have to do is multiply it by 2 to get the diameter.
44*2=88
Diameter=88 cm
Use matrices to determine the coordinates of the vertices of the rotated figure. Then graph the pre-image and the image of the same coordinate grid. Rot90 for UVW with vertices U(-4, 7), V(5, 4), and W(5, -5).
Answer:
The answer is A
Step-by-step explanation:
just got it right on edge :)
The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)
What is Rotation?A rotation is a type of transformation that rotates each point in a figure a specific number of degrees around a particular point.
90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y) 270° clockwise rotation: (x,y) becomes (-y,x)When we rotate a point around the origin by 90° clockwise or anti-clockwise, (x,y) becomes (y,-x) .
- Then matrix of the rotation 90° is
[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex]
We have the point U (-4, 7) and its image is
U' =[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}-4\\7\end{array}\right][/tex]
U' = [tex]\left[\begin{array}{ccc}-7\\-4\end{array}\right][/tex]
and, point V is (5, 4) and its image is
V' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\4\end{array}\right][/tex]
V' = [tex]\left[\begin{array}{ccc}-4\\5\end{array}\right][/tex]
and, point W is (5, -5) and its image is
W' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\-5\end{array}\right][/tex]
W' = [tex]\left[\begin{array}{ccc}5\\5\end{array}\right][/tex]
So, The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)

A road is inclined at an angle of 5°. After
driving 5,328 feet along this road, find the
driver's increase in altitude Round to the
nearest foot
Answer:
464 feet
Step-by-step explanation:
The Sine of the angle of inclination gives the increase in altitude.
This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e
Sin Ф = Opposite ÷ Hypotenuse
Sin 5° = O ÷ 5328
0·08716 = O ÷ 5328
Make O the subject and multiply every fraction by 5328
(0·08716/1 × 5328)= (O/5328 × 5328)
464·388 = O
∴ The increase in altitude is 464·388 feet
This is supposed to be to the nearest foot so we round off
464·388 becomes 464 feet
mr.floyd is laying grass squares in his backyard .He will cover the entire yard except for the vegetable garden.

Step-by-step explanation:
Given:
Dimension of vegetable garden = 15 ft by 25 ft
Dimension of garden = 8 ft by 8 ft
Find:
Remain garden Area
Computation:
Remain garden Area = Area of vegetable garden - Area of Garden
Remain garden Area = [(15)(25)] - [(8)(8)]
Remain garden Area = 375 - 64
Remain garden Area = 311 ft²

6. Sales associates at a local clothing
store eam a 2% commission on the
clothes they sell if an associate earned
$50 in commission, what was the value
of her sales? Explain how you can
check your answer.
Answer quick PLZZ no website
Answer:
$2500
Step-by-step explanation:
Given data
Percent commission from sale= 2%
We are told that an associate earned $50 from sales
Let the amount of the sales be x
so
2/100*x= 50
0.02x=50
Divide both sides by 0.02
x=50/0.02
x=2500
Hence the sales made was $2500
The money Mr. Jarod earns, m, varies directly with the number of haircuts he gives, h. He earns $15 for five haircuts. Which equation represents his earnings for the job?
Answer:
m/h = k
Step-by-step explanation:
Money earned = m
Number of haircuts = h
m α h
m = kh
k is the constant of proportionality
Amount earned for 5 hair cuts = 15
n = 5 ; m = 15
Earning for the job = k
From m = kh
Divide both sides by h
m / h = kh/h
m/h = k
15/5 = 3
Earning for the job = $3
subtract the cube root of the product of h and 3k from the square of the sum of p and q
Answer:
(p + q)² - ∛(h·3k) or (p + q)² - ∛(h·3k)
Step-by-step explanation:
Cube root of x: ∛x
Product of h and 3k: h·3k
Sum of p and q: p + q
*****************************
From (p + q)² subtract ∛(h·3k) This becomes, symbolically:
=> (p + q)² - ∛(h·3k)

The sum of two numbers is 400. The smaller number
is 100 less than the larger number, n.
What is the value of n?
a.150
b.200
c.250
d.300
Answer:
The answer is c, 250.
Step-by-step explanation:
Smaller number = n - 100
Bigger number = n
n + n - 100 = 400
2n = 500
n = 250
Check that this is true:
250 + 250 - 100 = 400

What is the area of the shaded figure
Answer:
42 square units
Step-by-step explanation:
imagine the rectangle around the original shape, it would be LxW which wold be 9 x 6 = 54. Then if you find the area of the two triangles cut out of the left and right sides, each triangle area is 1/2 base x height, which is 1/2(6x2)=1/2(12)=6 and x2 for 2 triangles and that = 12.
Now subtract 54-12=42 sq. units shaded.
