What is the rectangular form of 17(cos(315°) + isin(315°))?
The value of the expression 17[cos(315°) + isin(315°)] will be (17√2 / 2) – (17√2 / 2)i. Then the correct option is A.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The rectangular form of 17(cos(315°) + isin(315°)).
We know that the value of cos 315° and sin 315°.
[tex]\sin 315^o = \dfrac{-1}{\sqrt2}\\\cos 315^o = \dfrac{1}{\sqrt2}[/tex]
Then the value of the expression will be
⇒ 17[(1/√2) – (1/√2)i]
⇒ (17√2 / 2) – (17√2 / 2)i
Then the correct option is A.

Paola and Tom opened a lemonade stand. This week they sold 20 cups of lemonade and received $5 in tips. If they spend $30 on supplies, which inequality could be used to find x, the price of each cup they must sell to make a profit?
Answer:
20x + 5 < 30
Step-by-step explanation:
To make a profit, the price on supplies must be less than the amount at which they sold their wares
Since they received $5 in tip, the amount of profit left to be accounted for is 30-5 = 25
So now, we need the smallest price at which they will sell per lemonade to make a profit
Mathematically, that will be;
20x + 5 > 30
Using this inequality X they will know the value of x that will give them profit

The area of a circle, in terms of π, is 196π m2.
Find the value of the radius.
Step-by-step explanation:
if area of circle = pi times radius^2,
area of circle divided by pi = radius^2
so, square root (area of circle divided by 2) = radius.
so, 196pi = m2
approx 616
616=m2
sqrt 616 =m
approx value of radius is 25 or 24.8

There were 7,313 more searches in the library book checkout system in January than February. In February there were 8,972 searches, how many searches were done in both months?
Given:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February.
To find:
The searches in both months.
Solution:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February. So,
Searches in January = 8972 + 7313 = 16285
Now,
Total number of Searches in both months = January + February searches
[tex]=16285 + 8972[/tex]
[tex]=25257[/tex]
Therefore, total number of searches in both months is 25257.

Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of baskets made = 15
This was triple the number of baskets he made on Saturday.
This means,
3x = 15
Number of baskets made on Saturday = x
Now,
3x = 15
Divide both sides by 3.
x = 5
The number of baskets made on Saturday is 5.
Thus,
The equation can be used to find, x, the number of baskets Derek made on Saturday.
3x = 15
Option D is the correct answer.

Laura buys a saddle in the UK for £850 Delivery is free. Steve buys the same saddle from Holland for 990 Euros. He pays 15 Euros for delivery. £1 = 1.18 Euros Including the delivery charge, whose saddle is cheaper?
Answer:
Laura's saddle is cheaperStep-by-step explanation:
We want to convert from euros to pound and compare which purchase is more expensive.
given data
we are told that Steve buys the same saddle from Holland for 990 Euros
given the exchange rate in pounds, it will be
£1 = 1.18 Euros
x=990 Euros
cross multiply we have
x=990/1.18
x= £838.98
Steve buys at £838.98
delivery charge is 15 Euros to pounds
£1 = 1.18 Euros
x=15 Euros
cross multiply we have
x=15/1.18
x= £13.04
to expenses incurred by Steve= £838.98+£13.04

Gabriella ran several laps around a 1/4-mile track. Then she ran 2 1/2 miles on a trail. In all, she ran 4 miles. Write and solve an equation to find l, the number of laps Gabriella ran.
9514 1404 393
Answer:
1/4×l +(2 1/2) = 4l = 6Step-by-step explanation:
For l laps around a 1/4 mile track, the total distance is ...
l×(1/4)
After adding 2 1/2 miles to that, Gabriella's total distance was 4 miles:
l×(1/4) +(2 1/2) = 4 . . . . an equation to find l
__
We can solve this equation by subtracting 2 1/2, then multiplying by 4.
l×(1/4) = 1 1/2
l = 4(1 1/2)
l = 6
Gabriella ran 6 laps on the track.
