When the polynomial is written in standard form, what are the values of the leading coefficient and the constant? 5x + 2 - 3x^2

earnstyle [38]

Leading coefficient = -3
Constant = 2

When you order them in standard form, you need to put them in ascending order of the exponents. Therefore the -3x^2 would come first, which makes the number attached (-3) the lead coefficient.

Also, since the number (2) without an x attached would be last (due to the power of x technically being 0), than that is the constant.

A curve in polar coordinates is given by: r=9+3cosθ. Point P is at θ=21π/18 .?

ikadub [295]

Answer:

Step-by-step explanation:

Given that a curve in polar coordinates is given by:

r=9+3cosθ

a) At point P, we have

$θ=\frac{21\pi}{18}$

Substitute to get

$r=9+cos \frac{21\pi}{18}\\=9.3932$

b) Cartesian coordinate is

$x= rcos \theta=3.6934\\y =r sin \tjeta =8.6365$

c) At the origin r =0

when r =0

we have

$9+3cos\theta=0\\cos\theta =-3$

Since cos cannot take values as -3 it doe snot pass through origin.

1) Billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. Billy had 5 practices last week.

nignag [31]

1 ) Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that, 1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be: $(26400*5)yards = 132000 yards$

2) Mark's current age is $t$ years

So, his age was in 10 years ago $=(t-10)years$

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be : $t= 3(t-10)$

What are the coordinates of the point that is common to the graph of f(x) = (2/3) ^ x and the graph of f(x) = (3/2) ^ x

kiruha [24]

Answer:

Both point are y=0. The difference between the two is that 2/3 is always decressing and 3/2 is always incressing.

If a sponsored link was delivered 100 times and 10 people clicked on it, then the number of impressions is 100, the number of cl

Rudik [331]

Answer:

Option A.

Step-by-step explanation:

It is given that a sponsored link was delivered 100 times and 10 people clicked on it.

Number of impressions = 100

Number of clicks = 10

The formula for click-through-rate (CTR) is

$CTC=\dfrac{\text{Total measured clicks}}{\text{Total measured impression}}\times 100$

$CTC=\dfrac{10}{100}\times 100$

$CTC=10$

The click-through-rate (CTR) would be 10%. Therefore, the correct option is A.
