of a football team's season touchdowns, about 43% came by passing. If the team scored 28 touchdowns, how many were by other means?​

Answers

43% were from passing so 100% - 43% = 57% came by other means.

28 x 57% = 28 x 0.57 = 16

What is the sum? (2/5x+5/8)+(1/5x-1/4)

a. 3/5x+1/8
b.3/5x+3/8
c.3/5x+5/8
d.3/5x+7/8

Answers

the answer is B because when yku combine like terms (x) 2/5 + 1/5 you get 3/6. Then when you simplify the equations, you turn -1/4 into -2/8 to match the 5/8. From there you just subtract 2/8 from 5/8 getting 3/8.

The terms in the sequence decrease by the same amount each time:

9, 6 ,3 ,0, -3, -6

Work out ,in term of n, the nth term of the sequence

Answers

Answer:the nth term of the sequence, Tn= -3n +12

Step-by-step explanation:

The nth term of an arithmetic progression is given as

Tn=  a+ (n-1) d

where a= first term

and d = common difference

In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that  the number is decreasing by 3

The first term, a= 9

and common difference, d = -3

using our formulae

Tn=  a+ (n-1) d

Tn= 9 + ( n-1) -3

Tn=9- 3n+ 3

Tn= -3n +12

What is a formula for the nth term of the given sequence?
36, -48, 64...

Answers

Answer:

A formula for the nth term of the given sequence is:

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Step-by-step explanation:

Given the sequence

36, -48, 64...

We know that a geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Compute the ratios of all the adjacent terms

[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=-\frac{4}{3}[/tex]

Therefore, the given sequence is a geometric sequence.

As the first element of the sequence is

[tex]a_1=36[/tex]

so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Therefore, a formula for the nth term of the given sequence is:

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

3. Given the statement "x - 4 is a factor of f(x)= 5x* – 22x - 2x2 – 25x +4". explain how to verify the
statement is accurate.

Answers

Step-by-step explanation:

x - 4 = 0

=> x = 4

f(x)= 5x – 22x - 2x² – 25x +4

By remainder theorem,

f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4

    = 20 - 88 - 32 - 100 + 4 ≠ 0

Since the remainder is not 0, x - 4 is not a factor.

1. E = -20,000p + 90,000
R = -2,170p2 + 87,000p

Answers

The equations of E and R are illustrations of cost and revenue functions

The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

How to determine the break even point

The cost and the revenue functions are given as:

E = -20,000p + 90,000

R = -2,170p^2 + 87,000p

At the break even point, we have:

E = R

Substitute known values

-20,000p + 90,000 = -2,170p^2 + 87,000p

Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

Answers

Answer:

(0, 3)

Step-by-step explanation:

The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).

Answer:

y=3

Step-by-step explanation:

Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.

y = 1/7x + 16/7

y = 4/7x + 1/7

y = 4/7x - 1/7

Answers

Answer:

one of the 4 equations, you should test your luck, but 2 is my favorite number so you should select the second one

Step-by-step explanation:

y = 4/7x + 1/7.
Explanation: To find slope, you plug the two points into the equation (y2-y1)/(x2-x1). So, (7-3)/(12-5), or 4/7. This slope is then coefficient of x, showing 4/7x. You can clearly see that the y-intercept is positive, and infer that it is 1/7 based on the answer choices.
