Need help with my homework
Klio2033 [76]
Part A is basically asking you for the GCF (greatest common factor) between 63 and 36. To find this you find all the numbers that can be multiplied to form each number.

36:
1 * 36
2*18
3*12
4*9
6*6

63:
1*63
3*21
9*7

The GCF is 9.
Part B is asking how much the GCF can go into each type of flower.
4 rows of geraniums
7 rows of marigolds

Which function is increasingnon the interval (negative infinity, positive infinity)
BlackZzzverrR [31]

Answer:

h(x) = 2^(x) - 1.

Step-by-step explanation:

Let's look at each equation:

f(x) = -3x +7, Well as x increases, since it's multiplication, there are "going to be more" -3's, so it's going to be decreasing.

g(x) = -4(2^x). While 2^x is increasing, because "there are going to be more 2's multiplied by each other" as x increases, it's being multiplied by a negative number, so it's actually going to be decrasing

h(x) = 2^(x) - 1. Here's it's going to be increases as x goes towards infinity because "there are going to be more 2's multiplied by each other", and there isn't any negative sign, while there is a negative 1, it's constant, so the overall value will be increasing

What is the remainder when (3x4 + 2x3 − x2 + 2x − 19) ÷ (x + 2)?
mel-nik [20]

Answer: The remainder will be 5 only.

Explanation:

Since we have given that

f(x)=3x^4+2x^3-x^2+2x-19

and

g(x)=x+2

Now, using the division algorithm, we'll get,

f(x)=g(x)\times (3x^3-4x^2+7x-12)+5

When we compare it with  division lemma, which says that

f(x)=g(x)\times q(x)+r(x)

We get,

r(x)=5

Hence, the remainder will be 5 only.
