Answer correct for brainliest and also get a thanks !:-) answer A and B!

Answers

a) your iterative rule would be: 22,28,34,40....... it is because there are 22 in first row and it is increasing by 6 at each step....

b) Now, a(n) = 100, a=22, d=28-22 = 6

we know, a(n) = a+(n-1)d

100 = 22+(n-1)6

100-22 = 6n-6

78+6 = 6n

n = 84/6

n= 14

Select whether each function is linear or nonlinearY=9(2x)
Y=(5x+3)^2
Y=8x^2
Y=5x-3
Y=3x^2+2x-1

If I put ^ before a number it means it's an exponent if anyone doesn't know

Answers

Y=9(2x) and y = 5x - 3 are linear equations while others are non-linear.

The standard linear equation is in the form y = mx + b

Note that the highest degree of linear equation is 1 while that of non-linear is 2 and above.

From the given option, we can see that the equation with the highest degree of 1 are Y=9(2x) and y = 5x - 3 (These ar linear equations)

Other equations are non-linear in nature since they have a degree of 2 or more.

How many solutions does the following equation have? -25z+1+35z=10z+1 Choose 1 answer: A.No solutions B.Exactly one solution C.Infinitely many solutions

Answers

Answer:

Step-by-step explanation:

given

- 25z + 1 + 35z = 10z + 1 ( collect like terms on left side )

10z + 1 = 10z + 1

since both sides are the same then any value of z is a solution of the equation.

the equation has infinitely many solutions

Orly uses 2 cups of raisins for every 9 cups of trail mix she makes. How many cups of trail mix will she make if she uses 12 cups of raisins?

Answers

so ratio si 2 to 9 or 2:9
so 12 cups of rasins to x cups of trail mix
ratio is 12 to x or 12:x

it has to be the same ratio so makek fractions and
2/9=12/x
solve for x
mulitply both sides by x
2x/9=12
multiply both sides by 9
2x=108
divide by 2
x=54
answer is 54 cups of trail mix

First, I know that for 2 cups of raisins for every 9 cups of trail mix and I am going to divide, 9÷2 and got 4.5 so for every cup of raisins, I need to multiply it by 4.5 to get how much trail mix I had in total so I need to multiply 12× 4.5. to get my answer so 12×4.5=54 so I had 54 cups of trail mix.

I hope this helped

If (cos)x= 1/2 what is sin(x) and tan(x)? Explain your steps in complete sentences.

Answers

The correct answers are:
1) sin(x) = $( √(3) )/(2)$
2) tan(x) = $√(3)$

Explanation:
Given:
$cos(x) = (1)/(2)$

Step 1:
Since, according to the Trigonometric identity:
$sin^2(x) + cos^2(x) = 1$ -- (1)

Step 2:
Plug in the value of cos(x) in equation (1):
$sin^2(x) + ( (1)/(2) )^2 = 1 \n sin^2(x) + (1)/(4) = 1 \n sin^2(x) = (3)/(4)$

Step 3:
Take square-root on both sides:
$√(sin^2(x)) = \sqrt{(3)/(4)}$

sin(x) = $( √(3) )/(2)$

Now to find the tan(x), we would use the following formula:

tan(x) = $(sin(x))/(cos(x))$ --- (2)

Plug in the values of sin(x) and cos(x) in equation (2):
tan(x) = $( ( √(3) )/(2) )/( (1)/(2) )$

Hence tan(x) = $√(3)$

Answer:

The value of $\sin x=(√(3))/(2)$
