A linear model for the situation below passes through the orgin. Find the missing value. Round to the nearest ten if necessary.

1 answer:

8 0

The equation describing the situation is given by
y - 0 = (5 - 0)/(47.5 - 0) (x - 0)
y = 5/47.5 x
y = 2/19 x

Therefore, it will require 19(11)/2 = 104.5 minutes to jog 11 miles.

For this case we have the variable $x = -3$ :

$A) 6x = 6 (-3) = - 18\\B) 4x = 4 (-3) = - 12\\C) -3x = -3 (-3) = + 9\\D) -7x = -7 (-3) = + 21$

Now, matching each expression with its value we have:

A goes with 4

B goes with 3

C goes with 2

D goes with 1

ANswer:

A goes with 4

B goes with 3

C goes with 2

D goes with 1

I need help i forgot how to multiply decimals

Alekssandra [29.7K]

Stack the numbers on top of each other so the decimals are lined up. Get rid of the decimals and then multiply. Put the decimal point back in directly under where it was before

Mr. mole left his burrow that lies 7 meters below the ground and started digging his way deeper into the ground, descending at a

Dimas [21]

Answer:

$f(t)=-\frac{3}{2}t-7$

Step-by-step explanation:

We know that:

The initial conditions are -7 meters at 0 minutes.
Then, after 6 minutes, he was 16 meters below the ground.

According to these two simple facts we can found the linear function that describes this problem. First, the problem says that Mr. Mole is descending at a constant rate, which is the slope of the function. Now, to calculate the slope we need to points, which are $(0;-7)$ and $(6;-16)$ , where t-values are minutes, and y-values are meters. You can see, that the first point is the initial condition and the second point is 6 minutes later.

So, we calculate the slope:

$m=\frac{y_{2}-y_{1}}{t_{2}-t_{1}} \\m=\frac{-16-(-7)}{6-0}=\frac{-16+7}{6}=\frac{-9}{6}=\frac{-3}{2}$

From the slope we can see that Mr. Mole is descending, because it has a negative sign. Also, the point $(0;-7)$ is on the y-axis, because t is null, so -7 is part of the function. Therefore the function that describes this problem is:

$f(t)=-\frac{3}{2}t-7$

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed r

Rom4ik [11]

309,900.00
-61,980.00 20% down
 247,920.00 
rate = (6 / 1,200) = .005
months = 360
(See attached for loan payment formula)
Monthly Payment = [.005 + .005 / ((1.005^360)-1)] * 247,920.00
Monthly Payment = [.005 + .005 / (( 6.02257521226299)-1)] * 247,920.00
Monthly Payment = [.005 + (.005 / 5.02257521226299)] * 247,920.00
Monthly Payment = [.005 + 0.0009955053 ] * 247,920.00
Monthly Payment = [ 0.0059955053 ] * 247,920.00
Monthly Payment = 1,486.41 

answer is "c"
