Find the value of x if sin80 = Cos(90-x)

Answers

Answer: 80

Step-by-step explanation:

Sin x = cos (90-x)

Like sin 30 = cos (90-30) =cos 60

So

90-x=90-80

Then

X=80

Verify your solution by finding the sum of the angles of sin and cos, it will be 90

Answer:

Step-by-step explanation:

Sin Ф = Cos (90 - Ф)

Comparing with this

Sin 80 = Cos (90 - 80) = Cos 10

So, x = 80

Determine which functions have two real number zeros by calculating the discriminant, b2 – 4ac. Check all that apply.
f(x) = x2 + 6x + 8
g(x) = x2 + 4x + 8
h(x) = x2 – 12x + 32
k(x) = x2 + 4x – 1
p(x) = 5x2 + 5x + 4
t(x) = x2 – 2x – 15

Answers

Step-by-step explanation:

We need to write the function that have two real number zeros by calculating the discriminant i.e. [tex]b^2-4ac[/tex].

We know that,

If D>0  the roots are real and unequal

If D= 0 roots are real and equal

If D< 0 roots are imaginary or not real and unequal

Function (1)

[tex]f(x)=x^2 + 6x + 8\\\\D=6^2-4\times 1\times 8\\\\D=4[/tex]

D>0  the roots are real and unequal

Function (2)

[tex]g(x)=x^2 + 4x + 8\\\\D=4^2-4\times 1\times 8\\\\D=-16[/tex]

D<0  the roots are real and unequal

Function (3)

[tex]h(x)=x^2 -12x+32\\\\D=(-12)^2-4\times 1\times 32\\\\D=16[/tex]

D>0  the roots are real and unequal

Function (4)

[tex]k(x)=x^2 +4x-1\\\\D=(4)^2-4\times 1\times (-1)\\\\D=20[/tex]

D>0  the roots are real and unequal

Function (5)

[tex]p(x)=5x^2 +5x+4\\\\D=(5)^2-4\times 5\times 4\\\\D=-55[/tex]

D<0  the roots are real and unequal

Function (6)

[tex]t(x)=x^2 -2x-15\\\\D=(-2)^2-4\times 1\times (-15)\\\\D=64[/tex]

D>0  the roots are real and unequal

(1),(3),(4) and (6) have two real number zeroes.

Suppose an investment of $500 doubles in value every 15 years. How much is the investment worth after 30 years? After 45 years?Write an equation and solve

Answers

Answer:

Step-by-step explanation:

well all you have to do is 500 dollars times two, because it times each 15 years right and 30/15=2. So you do $500*2 which is $1000. And you get $1500 in 45 yrs.

So the equations are for each 15 yrs you add 500 dollars to the amount.

United Steel provides pensions to its employees. An individual pension is 2.3% of the

employee's average salary for the last five years of employment times the number of

years the employee worked for the company. Juan DeMarco worked for 30 years for

United Steel.

The annual salaries he received for his last five years were: $ 93,000, $ 94,000, $ 98,000,

$ 94,000, and $102,000.

What will his annual pension be?

Answers

Answer:

$66,378.

Step-by-step explanation:

Average salary for the last 5 years = (93000+94000+98000+94000+102000)

/ 5

= $96,200

So his pension = 96,000 * 0.023 * 30

= $66,378.

(a) The appropriate formula is C = 2πr.  Here r = 14 cm, so

C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²

(b) We use the same circumference formula:   C = 2πr  and solve it for r before inserting numeric values:

        C                                                 132 m               7(132 m)

r = --------         and in this case,   r = ------------------- = ------------- = 21 m

In order to use the Pythagorean Theorem, you must know the length or lengths of (all three sides/any 2 sides/any side) of the triangle and know that the measure of one of the angles is (greater than 90°/exactly 90°/less than 90°) .

Answers

Answer:

a) Any 2 sides

b) exactly 90°

Step-by-step explanation:

The point of the Pythagorean Theorem is to find the length of the hypotenuse using 2 sides.

This only works for right triangles.

Hope this helps!

-MoCKEry

Answer:

1) any two sides

2)exactly 90 degrees

Step-by-step explanation:

1) The pythagorean theorem only applies to right angle triangles

since right angle triangles measure 90 degrees exactly we will choose exactly 90 as an option.

2) so the formula for pythagorean theorem is a^2+b^2=c^2  where

a=side 1

b= side 2

c=hypotenuse(biggest side)

to find the hypotenuse you need to know both the values of a and b hence we will take the option "any two sides"

what is the zero of the function below?
f(x)=3x-15
A. -15
B. 0
C. 5
D. 3

Answers

Answer:

x = 5  (Answer C)

Step-by-step explanation:

Set f(x) = 3x - 15 = to 0 and solve for x:

3x - 15 =  0

Adding 15 to both sides isolates 3x:

3x = 15

Dividing both sides by 3 yields x = 5  (Answer C)

Find the mean absolute deviation (MAD) of the data in the pictograph

Answers

Answer:

1.5

Step-by-step explanation:

First, find the mean (average) of the data set.

mean = (x1 + x2 + ...)/N

where x1, x2, ... are the data points, and N the total amount of data points.

mean = (7 + 2 + 4 + 3)/4 = 4

Then, mean absolute deviation is computed as follows:

MAD = (|x1 - mean| + |x2 - mean| + ...)/N

MAD = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|)/4

MAD = (3 + 2 + 1)/4 = 1.5
