Mathematics
1 answer:
Lina20 [59]2 years ago
4 0

Answer:

Hi,

Step-by-step explanation:

Using Al'Kashi theorem (law of cosines),

x²=26²+19²-2*26*19*cos(31°)

x²= 190,11870690...

So

x=\sqrt{190.11870690} =13,7883540...\approx{13.8}

I hope that this is not a control.

A student wants to save at least $5000 for college. She begins with a savings account set up by her parents containing $2,500. E
Tamiku [17]

Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of  5000 dollars needed for college.

Step-by-step explanation: Im not good with equations but here  we go.

First: AS we know the account already had 2,500, and every month she deposits 50$.

What we can do is to divide 2,500 divided by 50 which will be 50.

How do you factor: x^2-4x+2xy-8y?
hoa [83]

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

(x^{2}−4x)+2xy−8y

Factor out the greatest common factor (GCF) from each group.

x(x−4)+2y(x−4)

Factor the polynomial by factoring out the greatest common factor,  x−4.

(x−4)(x+2y)

I believe this is correct. Good luck.

Y intercept <br> x intercept<br> and the slope
masha68 [24]

Answer:

y-intercept = (0, - 3)

x-intercept = (-6, 0)

slope = - 1/2

Step-by-step explanation:

The y intercept is the value of y when the x = 0. By looking at the graph, we can tell that when x = 0, y = - 3. Likewise for the x-intercept.

We can use the slope formula to determine the slope.

m = y2 - y1/ x2 - x1

You can choose any 2 points on the line and substitute in the formula. I chose the y and x intercepts for easier calculations.

m = - 3 - 0/ 0 - (- 6)

m = - 3/ 6

m = - 1/2
