Answer:

4 by 2

Step-by-step explanation:

you can basically guess and check with this question but I knew if it was a rectangle then 2 sides would be larger than the other. So I started off figuring out what times what equals 8 and I got 2 and 4. So I put those in for the side lengths and I got 12.

I think it will because 5 × 6 × 25 = 750 in.

The bat is 30 in.

So, I think it will fit.

Hope this helped☺☺

Answer:

$-2x - h - 3$

Step-by-step explanation:

Step 1: Define

Difference Quotient: $\frac{f(x+h)-f(x)}{h}$

f(x) = -x² - 3x + 1

f(x + h) means that x = (x + h)

f(x) is just the normal function

Step 2: Find difference quotient

<u>Substitute:</u> $\frac{[-(x+h)^2-3(x+h)+1]-(-x^2-3x+1)}{h}$
<u>Expand and Distribute:</u> $\frac{[-(x^2+2hx+h^2)-3x-3h+1]+x^2+3x-1}{h}$
<u>Distribute:</u> $\frac{-x^2-2hx-h^2-3x-3h+1+x^2+3x-1}{h}$
<u>Combine like terms:</u> $\frac{-2hx-h^2-3h}{h}$
<u>Factor out </u><em><u>h</u></em><u>:</u> $\frac{h(-2x-h-3)}{h}$
<u>Simplify:</u> $-2x - h - 3$

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Following are the differential equation:

$\to P(C,S)t+1 = P(C,S)t+(- 0.06Ct +0.04St, 0.06Ct - 0.04St ) \ \ \ \\\\or \ \ \ \ \ \ \ \\\\ \to (0.94Ct + 0.04St, 0.96St + 0.06Ct)$

In equation:

$\to t = 0, \ as \ 2019\\\\\to Ct = 10,000,000 \\\\\to St = 800,000,000\\$

$\to P(C, S)1 = (0.94Ct + 0.04St, 0.96St + 0.06Ct) \\\\$

$= (0.94(10000000) + 0.04(800000), 0.96(800000) + 0.06(10000000))\\\\ = (9,400,000 + 32,000), (768,000 +6000000))\\\\ = (9432000, 1368000)$

$\to P(C, S)2 = (0.94(9432000) + 0.04(1368000), 0.96(1368000) + 0.06(9432000))$

$=(8,866,080 + 54,720), (1,313,280 + 565,920)\\\\=(8,920,800, 1,879,200)$

iogann1982 [59]

Answer: Option C. [0.95, 1.59].

Step-by-step explanation:

We know that the mean is:

M = 1.27

and the margin of error is:

e = 0.32

This means that the actual value can be at a maximum distance of 0.32 from the mean.

then the interval will be:

[M - e, M + e].= [1.27 - 0.32, 1.27 + 0.32].= [0.95, 1.59].

The correct option is C.
