Answer:

the 3rd one

Step-by-step explanation:

i just took the test

Based on the model produced by the scatterplot, log of stock prices is calculated from the scatter plot and 10 is raised to the power of the result to obtain the estimated stock price. Hence, a reasonable estimate for the stock price would be ; $185.05

From the scatter plot model :

log y = 0.0022(95) + 2.0583

log y = 2.2673

Raise the power of both sides to the power of 10

[tex]y = 10^{2.2673} = 185.054 [/tex]

Therefore, a reasonble estimate for the stock price would be $185.05

Answer: C

Step-by-step explanation:

Answer:

26 degrees.

Step-by-step explanation:

We are given

We are trying to find angle measure of j.

Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.

[tex] \tan(x) = \frac{opp}{adj} [/tex]

[tex] \tan(x) = \frac{46}{93} [/tex]

since we are trying to find the angle measure apply inverse trig function

[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]

Plug 46 for opp and 93 for adj.

[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]

which is about 26 degrees.

Sure Amaya  , the grouping is the parenthesis, right?

Step-by-step explanation:

so  just add up.. the things outside of the parenthesis

-  [tex]4^{2}[/tex] * 4

so exponents come first in the order of what to do... right?

[tex]4^{2}[/tex] =16    okay , got that part, the next part is

16 * 4 = 64   okay got that part,  now

- 64   is what is subtracted from the grouping   , got it?

Hi! i see your having trouble let me help you :-)

Let's solve your equation step-by-step.

−4(x−3)=20

Step 1: Simplify both sides of the equation.

−4(x−3)=20

(−4)(x)+(−4)(−3)=20(Distribute)

−4x+12=20

Step 2: Subtract 12 from both sides.

−4x+12−12=20−12

−4x=8

Step 3: Divide both sides by -4.

−4x−4=8−4

x=−2

[tex]\Huge\boxed{74}[/tex]

Step-by-step explanation:

Hello There!

First things first, we need to find the value of x

If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x

180 = 2x + 3x - 5

step 1 combine like terms

2x + 3x = 5x

now we have

180 = 5x - 5 step 2 add 5 to each side

-5 + 5 cancels out

180 + 5 = 185

now we have 185 = 5x

step 3 divide each side by 5

5x/5=x

185/5=37

we're left with x = 37

Now we want to plug in 37 into x for angle A

angle a = 2(37)

2*37=74

so we can conclude that angle A = 74

Answer: x=9,-1

Step-by-step explanation:

First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8

Those numbers would be -9 & 1

-9+1=-8

-9x1=-9

Now we have

(x-9)(x+1)

x-9=0   x+1=0

 +9 +9   -1  -1

x=9      x=-1

Answer = -13 or 12

Step-by-step explanation:

let the two numbers be y and y+1

y(y+1)=156

y2 + y -156=0

y2 -12y+13y-156

y(y-12) +13(y-12)

(y+13) (y-12)

y+13=0

y= -13

y-12=0

y=12
