Answer:

3rd option

Step-by-step explanation:

- 1 ( $\frac{3x}{2y}$ )

- 1 is multiplying the complere fraction , not just 1 part of it , so

= - $\frac{3x}{2y}$

Disregard my work, but how do you get the answer? There is also a graph at the bottom which is optional to use.

f(x)= A( Bx+ C)+ D

\\\\
f(x)= A\sqrt{ Bx+ C}+ D

f(x)= A(\mathbb{R})^{ Bx+ C}+ D

f(x)= A sin\left( B x+ C \right)+ D

$\bf \bullet \textit{ horizontal shift by }\frac{ C}{ B}\\
~~~~~~if\ \frac{ C}{ B}\textit{ is negative, to the right}\\\\
~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}\\\\
\bullet \textit{ vertical shift by } D\\
~~~~~~if\ D\textit{ is negative, downwards}\\\\
~~~~~~if\ D\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{ B}$

with that template in mind.

since the original or "parent" function is y = x²−4x+3, if we change the "x" argument to "x-2", we end up with a horizontal shift.

the x-2 part would be in the template the Bx+C part, with B = 1 and C = -2, or a horizontal shift to the right of 2/1 or 2 units.

since the parent function has a point at (2, -1), if we move that horizontally only to the right, we'd end up at (4, -1).

What is the equation of the line with a slope of -1/2 that passses through the points (6,6)?

ivann1987 [24]

M = slope

Lets put this in point slope form, and slope intercept form.

y - 6 = -1/2(x - 6)
y - 6 = -1/2x + 3
+ 6 + 6

y = -1/2x + 9

Answer: y = -1/2x + 9

A ramp leads up to a building. the top of the ramp is 4 feet above the ground, and the bottom of the ramp is 18 feet from the bu

Radda [10]

Use the Pythagorean theorem

let = length of ram = l

l² = 4² 18²
l² = 16 + 324
l² = 340
l = 18.4390889146
l = 18.4 ft.

Priya's cat is pregnant with a litter of 5 kittens. Each kitten had a 30% chance of being chocolate brown. Estimate the probabil

aniked [119]

Answer:

So, the probability is P=0.3087.

Step-by-step explanation:

We know that Priya's cat is pregnant with a litter of 5 kittens, so n=5.

Each kitten had a 30% chance of being chocolate brown.

We get that p=0.3 and q=1-0.3=0.7.

We calculate the probability that exactly 2 kittens will be chocolate brown, so k=2.

We use the formula:

$\boxed{P(X=k)=C_k^n\cdot p^k\cdot q^{n-k}}$

we get

$P(X=2)=C_2^5\cdot 0.3^2\cdot 0.7^3\\\\P(X=2)=\frac{5!}{2!(5-2)!}\cdot 0.03087\\\\P(X=2)=10\cdot 0.03087\\\\P(X=2)=0.3087\\$

So, the probability is P=0.3087.

If line t is a transversal of lines l and m, name the angle relationship of the given angle pairs.

Ghella [55]

Answer:

$\angle 1\ and\ \angle 3$ are corresponding angles and are congruent to each other.

$\angle 8\ and\ \angle 4$ are alternate exterior angles and thus congruent to each other.

$\angle 2\ and\ \angle 3$ are interior angles on the same side, and they are supplementary(sum=180°).

Step-by-step explanation:

Given:

Line $l\parallel m$

Line $t$ is traversal.

By angle properties we can name the angle relationship of given angle pairs.

$\angle 1\ and\ \angle 3$ are corresponding angles and are congruent to each other.

$\angle 8\ and\ \angle 4$ are alternate exterior angles and thus congruent to each other.

$\angle 2\ and\ \angle 3$ are interior angles on the same side, and thus they are supplementary.
