Answer:
[tex] \frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y[/tex]
Step-by-step explanation:
We know that [tex] { \tan }^{2} y = { \sec }^{2} y - 1[/tex]
Also , [tex] { \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y } [/tex]
So ,
[tex] \frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y[/tex]
Mr Parsad places £1007 into a
savings account and gains 8%
interest per annum. How much
money is in the account after 9
year?
Answer:
$ 1,732.04
Step-by-step explanation:
A = $1,732.04
I = A - P = $725.04
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving our equation:
A = 1007(1 + (0.08 × 9)) = 1732.04
A = $1,732.04
The total amount accrued, principal plus interest, from simple interest on a principal of $1,007.00 at a rate of 8% per year for 9 years is $1,732.04.

Is x = –4 a valid solution this linear equation?
2x + 9(x – 1) = 8(2x + 2) – 5
Answer:
Yes it is!
Step-by-step explanation:
All you have to do is plug in -4 in place of all the x’s. You should get
-8x - 36 - 9 = -64x + 16 - 5
Simplified: -8x - 45 = -64x + 11
+45. + 45
-8x = -64x + 56
+64 +64
56 = 56
Answer = True
So yes -4 is a correct solution!

the ordered pair (1,-3) is a solution of the system
Answer:
False
Step-by-step explanation:
Find the solution of:
2x + 3y = -7 --› eqn. 1
-x = 2y --› eqn. 2
Rewrite equation 2
-x = 2y --› eqn. 2
Divide both sides by -1
x = -2y
Substitute x = -2y in equation 1.
2x + 3y = -7 --› eqn. 1
2(-2y) + 3y = -7
-4y + 3y = -7
-y = -7
Divide both sides by -1
y = 7
If y = 7, then (1, -3) cannot be the solution of the system of equations.
solve the system of equations using the linear combination method

On one shelf of the school library 1/2 of the books are about sports. Joyce sees that 3/4 of the sports books are about basketball. What fraction of the books on the shelf are about basketball
The fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].
We know that half of the books on the shelf are about sports, so if we let "x" represent the total number of books, the number of sports books would be [tex](\frac{1}{2})x[/tex].
Next, Joyce observes that [tex]\frac{3}{4}[/tex] of the sports books are about basketball.
To find the fraction of books about basketball, we need to multiply the fraction of sports books by the fraction of basketball books within that category.
Therefore, we have:
[tex](\frac{3}{4}) \times(\frac{1}{2} )x =(\frac{3}{8} )x[/tex]
So, the fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].

To buy a car, Mitchell borrowed $17,000 at an annual (yearly) simple interest rate of 9%. During his first year of this loan, he will owe the bank $1530 in interest.
Answer: True
Step-by-step explanation:
(1) 100% - 9% = 91% = .91
(2) .91 x 17,000 = 15470
(3) 17,000 - 15,470 = 1'530

b. Everybody needs somebody sometime.
c. The Broncos will win the Super Bowl or I'll eat my hat.
d. We can have donuts for dinner, but only if it rains.
e. Every natural number greater than 1 is either prime or composite.
f. This sentence is false.
Answer:
a. The sum of the first 100 odd positive integers - Not a statement
b. Everybody needs somebody sometime - Atomic statement
c. The Broncos will win the Super Bowl or I'll eat my hat - Molecular statement (disjunction)

Each month, a phone company charges $30 talk time plus $0.50 for each additional minute.
Write an expression to show the cost of a plan for one month???
Answer:
Step-by-step explanation: If 1 minutes of talk = 30 and texting = 30
and each additional minute of talk = 0.50
then the bill would be (for C = total cost)
C = 20+30+(0.45 • x)
OR
C = 50 + 0.45x
Answer:
30+.50m=c
Step-by-step explanation:
30 is the initial cost. Since its initial it is only a one time fee.
.50 is the cost per minute, since it says per you can automatically assume that it will be more than once.
M represents the minutes that they spend on the call, so if there was a 10 minute call, instead of m you would put 10, 10×.50.
But since there is no given time we have to put a variable, m, as a replacement.
The c is the variable for the cost.
