Answer:

QRS.

Step-by-step explanation:

The order of the letters must reflect the equal angles and their order.

Can someone explain to me how do I do this? <br><br>This is for AP Calculus

Brrunno [24]

1. As $x\to+\infty$ , the expression $x^3$ will remain positive and veer off to positive infinity as well. The constant term and coefficient on $x^3$ don't affect this result:

$\displaystyle\lim_{x\to\infty}(0.25x^3+3)=\infty$

In the opposite direction, $x\to-\infty$ means $x$ will be negative, so $x^3$ will also be negative. Then

$\displaystyle\lim_{x\to-\infty}(0.25x^3+3)=-\infty$

2. As $x\to+\infty$ , the exponent $4x$ will also go to positive infinity, so that

$\displaystyle\lim_{x\to\infty}2\cdot10^{4x}=\infty$

In the opposite direction, $4x$ would veer off to negative infinity. Then

$10^{4x}\to10^{\text{large negative number}}=\dfrac1{10^{\text{large positive number}}}$

and as $x$ gets larger in magnitude, this would force the expression to converge to 0, so that

$\displaystyle\lim_{x\to-\infty}2\cdot10^{4x}=0$

During a baseball season, Team A scores 9 runs for every 7 runs that Team B scores. The total number of runs scored by both team

SSSSS [86.1K]

Answer:

Each team ran (scored) 90 runs.

Step-by-step explanation:

Don't really know how to explain it but I'll show what I did.

First I understood that for every 9 runs team A runs, team B runs 7.

This means that if we multiply 9 by a number, we have to multiply 7 by the same number.

Now that we understand this, we need to figure out a number that when multiplied with 7 and 9 then added together equals 1440.

I'm pretty sure there was an easier way to do this but I did it the way I know will for sure give me the right answer and that's estimating that mystery number until you get it. Sorry my explanation wasn't the best.

Work:

9 x 90 = 810

7 x 90 = 630

810 + 630 = 1440
