A function is given by the equation h (x)=x 2 squared +6x-3. what is h (3)?

1 answer:

5 0

Your "<span>h (x)=x 2 squared +6x-3" is ambiguous. If you meant "x squared," then you need only write x^2 OR "x squared," but NOT "x 2 squared."

I will assume that by "</span><span>h (x)=x 2 squared +6x-3" you actually meant:

</span><span>h(x)=x^2 +6x-3. To find h(3), subst. 3 for x: h(3) = (3)^2 + 6(3) - 3, or

h(3) = 9 + 18 - 3, or h(3) = 24.</span>

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies.

eimsori [14]

Answer:

A. Comedy

Step-by-step explanation:

We are given that,

Movie type Number of movies

Comedy 8

Action 6

Fantasy 5

Drama 1

Then the total number of movies = 8+6+5+1 = 20

<h3><em>So, we will find the ratio of each type of movie out of total movies.</em></h3>

Ratio of comedy movies = $\frac{8}{20}=\frac{2}{5}$

Ratio of action movies = $\frac{6}{20}=\frac{3}{10}$

Ratio of fantasy movies = $\frac{5}{20}=\frac{1}{4}$

Ratio of drama movies = $\frac{1}{20}$

Since, we have,

<h3>Ratio of comedy movies = $\frac{8}{20}=\frac{2}{5}$ </h3>

Thus, 'For every 5 movies on the list, there are 2 COMEDY movies'.

So, option A is correct.

Triangle ABC below is reflected across the y-axis and then translated 1 unit right and 2 units down.

hodyreva [135]

Any point with coordinates (x, y) reflected across the y-axis is going to have the opposite x value that it did before.
You should be able to find the coordinates yourself for part a. (you didn't provide the original ones so I can't help you there)
Here is the "rule" for a reflection across the y-axis:
$(x,\ y)\rightarrow(-x,\ y)$
And when we go 1 unit to the right and 2 down, that's the same as
$(x,\ y)\rightarrow(x+1,\ y-2)$

Combining those into one rule is pretty simple, Use our result for the first in the second and we would get $(-x+1,\ y-2)$ , so the rule is
$\boxed{(x,\ y)\rightarrow(-x+1,\ y-2)$ .
Part A is asking for the coordinates after the reflection (x, y) ⇒ (-x, y).
Part C is asking for the coordinates after the full translation ⇒ (-x+1, y-2)

The area of a triangle is 10 square meters. The height is one meter longer than the base. What are the lengths of the base and h

Kamila [148]

Answer:

b=4, h=5

Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
