13. The third term in an arithmetic sequence is 10 and the fifth term is 26. If the first term is , which is an equation for the nth term of this sequence?

Answers

Answer 1

Answer: n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK

n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42

So the answer is B

What is the zero function of f(x)=x+10

I think that the zero function of this equation is subsitute 0 for x which gives us 10

If the zero function means that what value of x will make the equation 0 then the answer is -10

Solve the equation 4x^2-17x-15=0

Answers

$4x^2-17x-15=0\n 4x^2-20x+3x-15=0\n 4x(x-5)+3(x-5)=0\n (4x+3)(x-5)=0\n x=-(3)/(4) \vee x=5$

4x^2 - 17x - 15 = 0
(4x + 3)(x-5)
4x + 3 = 0
4x = -3
x = -3/4

x - 5 = 0
x = 5

Justin was asked to write equations based on the triangle below. So far he has come up with the following equations: Which of the following would be another correct equation?

Answers

Answer:

C: tan 60 = √3

Step-by-step explanation:

Let the adjacent part of the triangle be x and let the opposite side be y.

Thus, from trigonometric ratios;

x/10 = cos 60

We are given cos 60 = ½

Thus;

x/10 = ½

x = ½ × 10

x = 5

Similarly;

y/10 = sin 60

Now,from trigonometric relationship we know that; sin 60 = cos 30. Thus;

y/10 = cos 30

We are given cos 30 = (√3)/2

Thus;

y/10 = (√3)/2

y = 10 × (√3)/2

y = 5√3

Since it is a right angle triangle with one angle being 60°, it means the other one is 30° since sum of angles in a triangle is 180°.

Thus;

5/(5√3) = tan 30°

1/√3 = tan 30

Similarly;

5/10 = sin 60°

sin 60° = ½

Also;

tan 60 = (5√3)/5

tan 60 = √3

Also;

sin 30 = 5/10

sin 30 = ½

A shipping company charges 15 to ship a package and 5% of the shipping charge for insurance on the package what is the total cost to ship this particular itema $90.00
b 15.75
c 22.50
d 25.20

Answers

The total cost of shipping a package with the cost of $15 exclusive if 5% insurance is 15.75 dollars. This is calculate by getting first the 5% of 15 dollars, 15 dollars multiplied by 5%, equal to 0.75 dollars. Then it will be added to the shipping cost of 15, which is equal to 15.75 dollars.

The Waist to Hip Ratio (WHR) is a ratio, commonly expressed as a decimal that has been shown to be a good predictor of possible cardiovascular problems in both men and women. If a male has a WHR greater than 1, he is considered to be at high risk for cardiovascular problems. Calculate the WHR of a male with a waist measurement of 40 inches and a hip measurement 2 inches less.

40waist - 2 =38 hip
you divide the waist number by hip number

40/38= 1.05
