Answer:

Step-by-step explanation:

Its the fourth choice, 8000 is closer to 8132 so you would round that down instead of choosing 8500. Also, 8000 ÷ 20 = 400

If the lowest temperature in Whitesboro for the week was -1°F and the highest temperature was 20°F, what was the total change in

Talja [164]

Answer: The total change is 21.

Since you want to find the change from the lowest to highest, make it into a subtraction problem. First of all, take the smallest number in front of the largest.

20 -1

Next, add a minus sign in between, your equation should look like this:

20 - (-1) = x

Then, you cancel out the negative signs. After that you solve it

20 - (-1) -> 20 + 1.

Lastly, you add them together.

20 + 1 = 21.

In conclusion, the answer is 21.

Last question of my homework pls <3

dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

$x_{J}$ = $\frac{1(-2)+2(4)}{2+1}$ = $\frac{-2+8}{3}$ = $\frac{6}{3}$ = 2

$y_{J}$ = $\frac{1(1)+2(7)}{2+1}$ = $\frac{1+14}{3}$ = $\frac{15}{3}$ = 5

Thus J = (2, 5 )

2^x=3^x+1 what are the exact approximate solutions

Mashcka [7]

Answer:

Step-by-step explanation:

The goal of course is to solve for x. Right now there are 2 of them, one on each side of the equals sign, and they are both in exponential positions. We have to get them out of that position. The way we do that is by taking the natural log of both sides. The power rule then says we can move the exponents down in front.

$ln(2^x)=ln(3^{x+1})$ becomes, after following the power rule:

x ln(2) = (x + 1) ln(3). We will distribute on the right side to get

x ln(2) = x ln(3) + 1 ln(3). The goal is to solve for x, so we will get both of them on the same side:

x ln(2) - x ln(3) = ln(3). We can now factor out the common x on the left to get:

x(ln2 - ln3) = ln3. The rule that "undoes" that division is the quotient rule backwards. Before that was a subtraction problem it was a division, so we put it back that way and get:

$x(\frac{ln(2)}{ln(3)})=ln(3)$ . We can factor out the ln from the left to simplify a bit:
