Answer:

1

Step-by-step explanation:

Using the trig. identity

sin²x + cos²x = 1

Given

[tex]\frac{sin^4x-cos^4x}{sin^2x-cos^2x}[/tex]

[tex]sin^{4}[/tex]x - [tex]cos^{4}[/tex]x ← is a difference of squares and factors as

(sin²x - cos²x)(sin²x + cos²x), then fraction becomes

= [tex]\frac{(sin^2x-cos^2x)(sin^2x+cos^2x)}{sin^2x-cos^2x}[/tex] ← cancel (sin²x - cos²x) on numerator/ denominator

= sin²x + cos²x

= 1

Answer:

-62

Step-by-step explanation:

Step 1: Define

u = 18

x = -10

y = 8

u + xy

Step 2: Substitute

18 + -10(8)

Step 3: Evaluate

18 - 80

-62

Answer:

Step-by-step explanation:

For x:

8x = 18 - 2y

x = (18 - 2y)/8

For y:

2y = -8x + 18

y = -4x + 9

702 can not be written as the product of 2 prime numbers, because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore 702 is a prime number.

Answer:

16(2z -3)

Step-by-step explanation:

There are two ways of solving this problem.

List out the factors of the numbers:

32z - 48

= 32 * z - 48

32= 1, 2, 4, 8, 16, 32

48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

the largest common factor that both numbers have in common is 16,

So factoring the equations means the one has to divide the equation by 16 and write it outside of the parenthesis.

16 * ( 2 * z - 3)

16(2z -3)

Another way of solving the problem:

prime factorize the number:

32 = 2^5

48 = 2^4 * 3

Both numbers have 2^4 as their largest factor in common meaning that that is their GCF. 2^4 is 16.

Now factor out 16 and write it on the outside of the parenthesis.

16 * ( 2 * z - 3)

16(2z -3)

Answer:

16(2z -3)

Step-by-step explanation:

Answer:

last test grade=x     x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79

$2050

$20000×1.05×1.05 =

= $20000×1.05²

= $20000×1.1025

= $22050

$22050 - $20000 = $2050

The interest earned for a 2-year period is $2050

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, Ms Tabanelli deposits $20,000 in an account that has a 5% annual interest rate compound yearly, she does not add to or withdraw from the account for 2 years,

We know that,

[tex]A = P(1+r)^t[/tex]

A = amount

P = principal

r = rate

t = time

Putting all the values in the formula,

A = 20000(1+0.05)²

A = 20000(1.05)²

A = 20000×1.1025

A = 22050

Interest earned = Amount - Principal

= 22050 - 20000

= 2050

Hence, the interest earned for a 2-year period is $2050

Answer:

f(x)=x-5 is a linear function

Step-by-step explanation:

so there are no restrictions to what x can be. The domain is all real numbers. In interval notation, we show that is can be anything from negative infinity through infinity like this: This says that the lower limit of the domain is negative infinity and the upper limit is positive infinity.
