Answer:
tan^2 60 - sin^2 45
= (√3)^2- (1/√2)^2
= 3-1/2
= 6-1/2
= 5/2
Answer:
[tex]\frac{5}{2}[/tex]
Step-by-step explanation:
The exact value of tan(60) is sqrt(3), and sin(45) is 1/sqrt(2)
tan^2 (60) - sin^2 (45)
[tex]=(\sqrt{3})^2-(\frac{1}{\sqrt{2}} )^2\\=3-\frac{1}{2}\\ = \frac{5}{2}[/tex]

Can someone tell me what a linear function is? Sorry, I'm just really confused. Whoever replies first will get marked Brainliest!! (Also, I am giving 50 points.)
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer:
A linear function is described below
Step-by-step explanation:
A linear function describes a proportional relationship in with 1 input has only 1 output, however more than one input may have the same output. There may be many steps to find the outcome of an input
The formula for simple interest is I=Prt,I=Prt, where II is the interest earned, PP is the principal, rr is the interest rate and tt is the number of years. Solve the formula for tt in terms of P,P, II and r.r.
Answer:
t = I/pr
Step-by-step explanation:
I = prt
divide both sides by pr
i/pr = prt/pr , pr cancel out
I/pr = t
t = I/pr

What are Decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point.

Aloysius was 3 times as old as his son 8 years ago. How old is his son now if
their total age is 68 years now?
9514 1404 393
Answer:
21
Step-by-step explanation:
8 years ago, both were 8 years younger, so the total of their ages would have been 68 -2×8 = 52. If the ratio of their ages was 1 : 3, then the son's age then was 1/(1+3) = 1/4 of the total. 1/4×52 = 13.
Now, 8 years later, the son's age is 13 +8 = 21.
__
Then, Aloysius was 3×13 = 39. Now, Aloysius is 39+8 = 47, and the sum of their ages is 21 +47 = 68, as required.

Which is the equation of the circle that has a diameter with endpoints located at (0, –3) and (6, 5)?
(x – 6)^2 + (y – 5)^2 = 100
(x – 3)^2 + (y – 1)^2 = 25
x^2 + (y + 3)^2 = 100
(x – 5)^2 + y^2 = 25
The equation of the circle that has a diameter with endpoints located at (0, –3) and (6, 5) is;
(x – 3)² + (y – 1)² = 25The midpoint of the diameter of a circle is it's center.
As such; the coordinates of its center are;
x = (0 + 6)x = 3y = (-3 + 5)/2y = 1The coordinates of the center are then; (3, 1)
The radius of a circle is half the length of the diameter;
Radius, r = d/2where; d = √(6-0)² + (5-(-3))²d = √36 + 64d = √100d = 10Therefore, radius, r = 10/2 = 5.
Therefore, the equation of the circle usually takes the form;
(x -f)² + (x -g)² = r²In this scenario; the equation is;
(x – 3)² + (y – 1)² = 25.Read more;;

Aiden makes $22 per hour and Parker makes $26 per hour. Additionally, this week Aiden made a bonus of $100. Given that A and P represent the number of hours worked by Aiden (A) and Parker (P), which expression can be used to represent their combined earnings for the week?
A) 24AP + 100
B) 24 + AP + 100
C) 22A + 26P + 100
D) 22A + 26P(100)
Answer:
It's C
Step-by-step explanation:
So if Aiden earns 22 per hour and Parker 26 per hour too you need to add 22+26 and Aiden had a bonus of $100 so you need to do this 22+26= __ + 100 =
Hope it helps
The expression that can be used to represent their combined earnings for the week is 22A + 26P + 100: Option C is correct
Let the amount that Aiden made per hour be A
Let the amount that Parker made per hour be P
Bonus earned by Aiden this week = $100
If Aiden makes $22 per hour, the total amount made by Aiden = 22A + 100
If Parker makes $26 per hour, the total money made by Parker = 26P
Total earning = total amount made by Aiden + total amount made by Parker
Total earning = 22A + 100 + 26P
Hence the expression that can be used to represent their combined earnings for the week is 22A + 26P + 100
