Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

Answer:

C) 5x + 13x = 180

Step-by-step explanation:

As, the sum of the angles of the above diagram is 180 °

So if we add them we get 180°

So, 5x + 13x = 180°

So option (C) is right

Answer:

5086.8 cubic yards

Step-by-step explanation:

Given data

Height = 20yards

Diamter= 18 yards

Radius= 9 yards

The expression for the volume of a cylinder is given as

V=πr^2h

substitute

V=3.14*9^2*20

V=3.14*81*20

V=5086.8 cubic yards

Answer:

-5,-3 and 3,5

Step-by-step explanation:

Answer:

1.)x=-5, x=3

2.)√10+4, x=√10+4

Step-by-step explanation:

1.) 2(x+1)^2=32

(x+1)^2=16

x+1=±4

x=1=-4

x=1=4

x=-5, x=3

2.)3(x-4)^2=30

(x-4)^2=10

x-4=±√10

x-4=-√10

x-4=√10

x=-√10+4, x=√10+4

The 25th term of the given arithmetic sequence is -19.

The given arithmetic sequence is 53, 50, 47, 44, 41.

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d

Here the first term of the sequence is a=53 and the common difference is

50-53=-3

Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get

a25=53+(25-1)×(-3)

= 53+24×(-3)

= 53-72

= -19

Therefore, the 25th term of the given arithmetic sequence is -19.

Answer:

D) Complementary

Step-by-step explanation:

Angles are complementary if they add up to 90°. The image shown showcases that the angles are 90° because of the box on the corner.

Supplementary means it adds up to 180° which would be a straight line, this is not the case where this is shown.

Answer:

c is correct

Step-by-step explanation:

if u have the equation y = a sin b (x),

a is the amplitue (regardless of + or - before it) and 2pi / b = period. so we can deduce that a = +5 or -5 and b = 2, but then it says a>0, so therefore a must be 5 and b is still 2, so the equation is y= 5 sin2(O)

Answer:

[tex]m(c(a)) = 4.8875a[/tex]

Step-by-step explanation:

The missing parameters are:

[tex]c(a) = 4.25a[/tex] --- Cost of marble countertops

[tex]m(c) = 1.15c[/tex] --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

[tex]c(a) = 4.25a[/tex]

[tex]m(c) = 1.15c[/tex]

[tex]m(c) = 1.15c[/tex] can be written as:

[tex]m(c(a)) = 1.15*c(a)[/tex]

Substitute: [tex]c(a) = 4.25a[/tex]

[tex]m(c(a)) = 1.15*4.25a[/tex]

[tex]m(c(a)) = 4.8875a[/tex]

Hence, the cost of marked up price is: [tex]m(c(a)) = 4.8875a[/tex]

Answer:

134 square inches

Step-by-step explanation:

To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).

Large sides on front and back: 8x6=48

Slim sides to the right and left: 1x6=6

Slim sides on top and bottom: 8x1=8

Then combine:

48+48+6+6+8+8=134
