# If Sin0= 1/2, What Is The Cos 0, Tan 0, And The Angle? (2023)

Mathematics High School

Use the special triangle 30-60-90 degrees which has side Hyp = 2 , Opp = 1 and adj = sqrt3

so sin O = opp/hyp = 1/2
cos O = adj / hyp = sqrt3 / 2
tan O = opp/adj = 1 / sqrt3 - or we could write this as sqrt3 / 3

Jen wants to save money for the future. Jen invests \$700 in an account that pays an interest rate of 6.75% How many years will it take for the account to reach \$16,300. Round your answer to the nearest hundredth

16300=700(1.0675)^t
Solve for t
t=log(16,300÷700)÷log(1.0675)
t=48 years

Rewrite the function y = x2 - 6x + 14 in vertex form, y = (x - h)2 + k.

y = x^2 - 6x + 14
y = x^2 - 2 . (x) . (3) + 9 + 5 ....... (using (a-b)^2 = a^2 -2ab+b^2)

Divide the coefficient of x by 2 -6 / 2 = -3;

y = (x - 3)^2 + k
y = (x - 3)^2 - 9 + 14
y = (x-3)^2 + 5 is ur answer

the ordered pairs below represent a linear relation between x and y. (-3,0) (-2,4)(-1,8)(0,12)(1,16)(2,20). which of the following is a correct statement about this relation

Step-by-step explanation:

Given are ordered pairs that represent a linear relation between x and y. (-3,0) (-2,4)(-1,8)(0,12)(1,16)(2,20).

We find that for a unit increase in x, y increases 4 units for all x.

i.e. slope is constant.

So the relation is linear.

The linear relation would be of the form

y = mx+b where m represents the slope, and b y intercept

Here m =4 and b = 12

So the relationship is linear and represented by the equation

C(r), the circumference of a tire, is based on the radius, r. What is an appropriate domain for the function?

Given:

C (r) is the circumference of a tire
The appropriate domain for the function is needed.

First, we set-up the equation for the circumference of a circle, assuming that the tire is a perfect circle:

C (r) = 2 * pi * r

the domain of the function is all values of r greater than zero. It can also be written as [1, infinity)

If f(x) varies directly with x2, and f(x) = 96 when x = 4, find the value of f(2). 192 72 32 24

F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6

PLZ HELP WILL GIVE 10 PTS AND BRAINLIEST!!! Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the numbers is –99.

Which equation can be used to find m, the midpoint of the two numbers?
(m – 5)(m + 5) = 99
(m – 10)(m + 10) = 99
m2 – 25 = –99
m2 – 100 = –99

"Two numbers are 10 units away in different directions from their midpoint, m, on a number line" so these two numbers are 20 units apart (2*10 = 20) if x and y are the two numbers, then x-y = 20 where x is the larger number we also know that x*y = -99 so one of the numbers is positive while the other is negative. i think its (x-10)(x+10)=-99. hope i could help.

m2 – 100 = –99 or D

Hope this helps!

In the diagram, all measurements are in centimetres. The lengths of the side of the quadrilateral are 2r+5, 2r, 4r-3 and r. Find an expression, in terms of r, for the perimeter of the quadrilateral. Give your expression in its simplest form.

The perimeter is simply the sum of all sides so:

p=2r+5+2r+4r-3+r combine like terms...

p=9r+2

The expression for the perimeter of the quadrilateral is cm.

Step-by-step explanation:

The lengths of the side of the quadrilateral are .

Perimeter means the sum of all side lengths in any geometric figure.

If the perimeter is , then.....

So, the expression for the perimeter of the quadrilateral is cm.
