Answer:

A dilation of 2 and a reflection across the y-axis.

Step-by-step explanation:

Dilating it by two, makes it bigger. Which eliminates two. Then, if you rotated 90 degrees clockwise, it wouldn't end up in the correct placement. But, If you reflected it across the y-axis, it would end up in the correct place.

Solve for i in the following equation by means of linear interpolation (1 + i)^10 - 1/ i = 25

lesya692 [45]

Answer:

i = 0.5049202164

Step-by-step explanation:

the given equation is:

$\frac{(1+i)^{10-1}}{i} = 25 \\ \\ (1+i)^{10} = 25i + 1 \\ \\ (1+i)^{10}-25i = 1 \\ \\ Taking \ log \ of \ both \ sides ; we \ have: \\ \\ log(1+i)^{10} - log (25 \ i) = log (1) \\ \\ 10 \ log (1+i) - \ log \ (25 \ i) = 0 \ \ \ \ \ (since : log (1) = 0 )) \\ \\ \ log (1+i) = log \ (25 \ i) ^{1/10} \\ \\ log(1+i) = log (1.3627429+0.2158372i) \\ \\ 1+i = 1.3627429+0.2518372 \ i$

$[ 1 - 0.2518372]i = 1.3627429 -1 \\ \\ 0.784162729 = 0.3627429 \\ \\ i = \frac{0.3627429}{0.784162729} \\ \\ i = 0.5049202164$

The yard behind the Cindy’s house is rectangular in shape and has a perimeter of 72 feet. If the length l of the yard is 18 feet

PtichkaEL [24]

Let
L----------> the length of the yard
W--------> the width l of the yard

we know that
the perimeter is equal to
 $P=2*[W+L]$
$72=2*[W+L] \\ 36=W+L$ --------> equation 1
$L=W+18$ ------> equation 2
substitute equation 2 in equation 1
 $36=W+18+W \\ 36=2W+18 \\ W=(36-18)/2$
$W=9 ft$
$L=W+18 \\ L=9+18 \\ L=27 ft$

we know that
Area of the rectangular yard is equal to
 $A=L*W \\ A=27*9 \\ A=243 ft^{2}$

Mr. Clark plans to spend no more than $400 on sandwiches and water for a work meeting. Each case of water costs $7.00 and each s

Alla [95]

Answer:

$7w+5s\leq 400$

Step-by-step explanation:

Money to be spent is not more than $400.

Cost of a case of water = $7

Cost of each sandwich = $5

Let number of cases of water bought be $w$

Number of sandwiches bought be $s$

From the question we get

$7w+5s\leq 400$

The inequality which would determine how many sandwiches, and how many cases of water that can be bought is $7w+5s\leq 400$ .

jessie estimates the weight of her cat to be 8 pounds the actual weight was 10 pounds. find the percent error

seraphim [82]

Answer: She was off by 25%

Step-by-step explanation: I used proportions to solve this. 100% and 8 are the same because 100% was what she thought the weight of the cat was. So this is one side of the proportion. The other side, we need a variable which is X. X is the unknown percentage. X is equal to 10. I then did 100% x 10 which is 1000 then divided it by 8 which is equal to 125%. 125% - 100% = 25%.
