If C = x2 + 7 and D = 3x2 - 4x + 3, find an expression that equals 3C + 3D in standard form.​

Answers

Answer 1

Answer:

The new expression is:  12 x^2 - 12 x+ 30

Step-by-step explanation:

if C = x^2 + 7

and

D = 3 x^2 - 4 x + 3

Then, 3 C + 3 D can be obtained via:

3 ( x^2 + 7 ) + 3 ( 3 x^2 - 4 x + 3 )  = 3 x^2 + 21 + 9 x^2 - 12 x + 9 =

= 12 x^2 - 12 x+ 30

An advertising agency notices that approximately 2 in 50 potential buyers of a product sees a given magazine ad, and 1 in 7 sees a corresponding ad on television. One in 100 sees both. One in 5 actually purchases the product after seeing the ad, 1 in 10 without seeing it. What is the probability that a randomly selected potential customer will purchase the product

Answers

Answer:

the probability that a randomly selected potential customer will purchase the product is 0.11728

Step-by-step explanation:

Given the data in the question;

by hypothesis, let the event be given as;

M = buyers sees a given magazine ad of the product

T = buyers sees a given television ad of the product

[tex]P_{A}[/tex] = buyer purchases the product after seeing the ad

[tex]P_{A"}[/tex] = buyer purchase the product without seeing the ad

from the information given in the question;

P(M) = (2/50 ) = 0.04,  P(T) = ( 1/7) = 0.1428,  P(M∩T) = (1/100) = 0.01,

P([tex]P_{A}[/tex]) = (1/5) = 0.2, p( [tex]P_{A"}[/tex]  ) = (1/10) = 0.1

now, the probability that the buyer sees the ad of the product will be;

P( M ∪ T ) = P( M) + P(T) - p( M ∩  T)

P( M ∪ T ) = 0.04 + 0.1428 - 0.01

P( M ∪ T ) = 0.1728

The probability that the buyer does not see the ad of the product will be;

P( M ∪ T )' = 1 - P( M ∪ T )

= 1 - 0.1728

= 0.8272

Now, the probability that a randomly selected potential customer will purchase the product will be;

P(P) = P([tex]P_{A}[/tex]) P( M ∪ T ) + p( [tex]P_{A"}[/tex]  )P( M ∪ T )'

P(P) = (0.2)(0.1728) + (0.1)(0.8272)

= 0.03456 + 0.08272

P(P) = 0.11728

Therefore, the probability that a randomly selected potential customer will purchase the product is 0.11728

Find the measure of angle2

I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense

Answers

Well, we are asked to simplify and solve this multiplication problem.
So, at first, this looks a little bit tricky but, we can actually break it down and then multiply with easy numbers.
First off, we can multiply 4 by 9 which is 45 however, we still have that major 50 so, to make it easier, we can just change the 50 to a 5 and then add the 0 at the end when we get our answer.

45 * 5
= 225

Lastly, we just need at put and add a zero (0) to our answer so, in conclusion, the answer to this question is: 2250.

Answer:

OBTUSE

Step-by-step explanation:

We can determine this based on the the pythagorean theorem!

[tex]a^{2}+ b^2 = c^2[/tex]

With Pythagorean Theorem, c is the longest length in the triangle... So, if c = a squared plus b squared, then it is a right triangle! If c is less, it is acute, and finally, if C is more than the two - then it is obtuse!

So let's see...

[tex]8^{2} +6^2 ? 12^2\\64 + 36 ? 144\\100 < 144[/tex]

This is an OBTUSE triangle, since c adds up to be more than a and b.

What is simplification?

Simplification means to make any equation simple or any large equations to a simple form, simplification can be done with mathematical formula and done for all operators in mathematics.

Given r = d/2

when we transfer digits to other sides of equal they change their sign,

plus tends to minus or vice versa,

and multiply tends to divide or vice versa.

so d = 2r

Hence the solution for d is 2r

g(x)=w^2+7w-7 and f(x)=4w-8 and (f+g)(5)=

Answers

The value of (f + g)(5) is 65

Function

Function relates input to output . Therefore,

g(x) = w² + 7w - 7

f(x) = 4w - 8

Therefore,

(f + g) = w² + 7w - 7 + (4w - 8)

(f + g) = w² + 7w - 7 + 4w - 8

(f + g) = w² + 11w - 15

Finally,

(f + g)(5) = 5² + 11(5) - 15

(f + g)(5) = 25 + 55 - 15

(f + g)(5) = 80 - 15

(f + g)(5) = 65
