Which function is equivalent to y = 3(x + 2)2 + 7 ?

Mathematics
1 answer:
Troyanec [42]2 years ago
5 0

Step-by-step explanation:

<u>Our function:</u>

y = 3(x + 2)^{2}  + 7

<u>Include the exponent:</u>

y = 3(x^{2}  + 4) + 7

<u>Use the Distributive Property:</u>

y = 3 {x}^{2}  + 12 + 7

<u>Add:</u>

\boxed{y = 3 {x}^{2}  + 19}

The general term of an arithmetic sequence is tn = 32 + 3n, where n ∈N and n ≥ 1. The sequence is A) 32, 35, 38, 41, 44, 47,...
den301095 [7]

Answer:

35,38,41,44,47,50,....

Step-by-step explanation:

n ∈N means that n is an element of Natural numbers

Natural numbers are whole non-negative numbers

n ≥ 1, means that n = 1, 2, 3, 4, 5, 6,........

tn = 32 + 3n

the first term t1 = 32 + 3(1)

                            32 + 3 = 35

the second term t2 = 32 + 3(2)

                                   32 + 6 = 38

the third term t3 = 32 + 3(3)

                              32 + 9 = 41

HURRY I need help Three corporations each own land. Corporation A owns 3.2 × 105 acres, corporation B owns 4 × 104 acres, and co
Ne4ueva [31]

Answer:

Corp A. 320,000

Corp B. 40,000

Corp C. 430,000

Corp C owns the most land, Corp A owns 8 times more land.

Explanation:

3.2.• 10^5 = 3.2 • 100,000 = 320,000

4 • 10^4 = 4 • 10,000 = 40,000

4.3 • 10^5 = 4.3 • 100,000 = 430,000

40,000 < 320,000 < 430,000

320,000 ÷ 40,000 = 8

Which diagram shows parallel lines cut by a transversal?
Arada [10]
Only the third model shows parallel lines cut by a transversal. 

We can solve this problem by using some properties that parallel lines cut by a transversal have. First of all, corresponding angles are congruent, and since the angles in figure 1 are corresponding but not congruent, that means that figure one is out. 

In addition, in figure two, alternate exterior and interior angles of parallel lines intersected by a transversal are congruent, so since they are not in the picture, that means that this figure is also out. 

Figure three is correct because since those are same side interior angles, they need to be supplementary for those to be two parallel lines intersected by a transversal. Since they do, in fact, add up to 180°, that means that the answer is figure three.

What is the equation of the line that passes through the point (4,0) and has a slope<br> of -2
N76 [4]

Answer: y=-2x+8

Step-by-step explanation: Write a table of values where for every x y goes down 2 to find the y intercept (0,8) so it would be 8. The slope is -2 and that is all you need to write the equation.

(20 points) A statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s
Nimfa-mama [501]

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}
