The function sin) = 2n - 5 represents the value of the nth term in a sequence. What is the sum of the 1st and 6th terms of the sequence?

Answers

Answer:

Step-by-step explanation:

Using the nth term formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₆ = 2(6) - 5 = 12 - 5 = 7

Then

a₁ + a₆ = - 3 + 7 = 4

In step 2 the 6(1 * x) is supposed to be 6 * 6x.

Answer:

If the correction of 6 * 6X is accurate then I hope this is the answer.

Step-by-step explanation:

6(6x)+3x=3+3x+5

1. First multiply 6 by 6

36x+3x=3+3x+5

2. Then add 36X and 3X

39x=3+3x+5

3. After that add 3 and 5

39x=3x+8

4. Subtract 3x from both sides of the equation.

39x−3x=8

5. Subtract 3x from 39x

36x=8

What is the vertex of the graph of the quadratic function f(x) = x2 + 6x +10?

F (3,-1)

G(-3,-1)

H(-3,1)

J(3,1)

Answers

Answer:

(-3, 1) (Answer H)

Step-by-step explanation:

f(x) = x^2 + 6x +10 can be rewritten by "completing the square" as

f(x) = (x + 3)^2 + 1, and by comparing this to y = (x - h)^2 + k, we see that h is -3, k is 1, so the vertex, (h, k), is at (-3, 1) (Answer H)

prisim a and prisim b have the same volume. which could be the dimensions of prisim b?

Answers

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

8x4x5 = 160

4x4x10 = 160

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

First we must find the volume of prism A

Assuming that the prism is a rectangular prism we can easily calculate the volume by multiplying the length by the width by the height

So V = 8 * 4 * 5

8 * 4 = 32

32 * 5 = 160

Hence, the volume of prism a is 160ft²

The question states that the volume of prism A is the same as the volume of prism B. Given that information we want to find the possible dimensions of prism B such that volume of prism A = volume of prism B.

We can do this by find the volume of each answer choice ( again, assuming that their rectangular prism )

For the first answer choice

4 * 4 * 10 = 160

160 = 160 however lets check the other answer choices.

For the second answer choice:

5 * 4 * 7 = 140

140≠160 therefore the second answer choice is not correct

For the third answer choice

8 * 4 * 6 = 192

192 ≠ 160 therefore the third answer choice is not correct

For the fourth answer choice

I can't see the dimensions, however we already know that the answer is the first answer choice.

The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given sin 0 = 2/5, find cos 0.
cos O = ✓21/ [ ? ]
Simplify the fraction.

Answers

Answer:

cos (theta) = √21/5

Step-by-step explanation:

sin (theta) = 2/5

(sin (theta))^2 = 4/25

4/25 + (cos (theta))^2 = 1

(cos (theta))^2 = 1 - 4/25 = 21/25

cos (theta) = √21/5
