Find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of -1. Show your work for full credit.
Answer:
(-1,-1)
Step-by-step explanation:
x = rcos(theta)
-1 = r cos(-3pi/4)
-1 = r(-sqrt(2)/2)
r = sqrt(2)
y = rsin(theta)
y = sqrt(2)sin(-3pi/4)
y = -1

1 foot = 12 inches. 1 inch = 2.5 centimetres. Change 5 feet 10 inches to centimetres
I guess the answer should be 177.8 cm.
The measurement of 5 feet 10 inches to centimeters is 175 centimeters.
What is Unit of Measurement?Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.
Here we have to convert the units of measurement feet and inches to centimeters.
We have,
1 foot = 12 inches and 1 inch = 2.5 centimeters
We have to change 5 feet 10 inches to centimeters.
1 foot = 12 inches
⇒ 5 feet = 12 × 5 inches
= 60 inches
So, 5 feet 10 inches = 60 inches + 10 inches
= 70 inches
1 inch = 2.5 centimeters
70 inches = 70 × 2.5 centimeters
= 175 centimeters
Hence we got 5 feet 10 inches as 175 centimeters.

Tom is 77 inches tall and shrinking at a rate of 0.75% every eyar. How tall will he be after 15 years?
Whats the exponential function
Answer:
The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.
Step-by-step explanation:
Since Tom's initial height is 77 inches. After one year:
height(1) = 77*(1 - 0.0075) = 77*0.9925
After two years:
height(2) = height(1)*(0.9925) = 77*0.9925*(0.9925) = 77*(0.9925)²
After three years:
height(3) = height(2)*0.9925 = 77*(0.9925)²*0.9925 = 77*(0.9925)³
And so on, therefore the expression that represents his height is:
height(n) = 77*(0.9925)^n
Where n is the number of elapsed years. For 15 years we have:
height(15) = 77*(0.9925)^(15) = 68.7778 inches
The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

David correctly factored the expression m^2 - ono
12m - 64.
Which expression did he write?
(1) (m-8)(m - 8) (3) (m - 16)(m + 4)
(2) (m - 8)(m + 8) (4) (m +16)(m - 4)
Explain why
Answer:
the correct option is number (3). It corresponds with the expression David factorised.
Step-by-step explanation:
David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.
(1) (m - 8)(m - 8) = (m - 8)²
= m² - 16m + 64
NOT THIS
(2) (m - 8)(m + 8) = m² - 8²
= m² - 64
NOT THIS
(3) (m - 16)(m + 4) = m² + 4m - 16m - 64
= m² - 12m - 64
THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED
(4) (m + 16)(m - 4) = m² - 4m + 16m - 64
= m² + 12m - 64

Math problem: Pirate Captain William Hawk left his hat on Treasure Island. He sailed 18km northeast through the Forbidden Straight, the 11km southeast to his home before realizing it was missing. If he sent his parrot to fetch his hat, how far did it need to fly?
Answer:
7 km
Step-by-step explanation:
If I subtracted 18km by 11km my answer would be 7km
Answer:
21.1 km
Step-by-step explanation:
The northeast line and the southeast line will make a right angle so use the Pythagorean Theorem: a^2 + b^2 = c^2 and calculate c.
18² + 11² = c²
324 + 121 = c²
445 = c²
c = 21.1 km

what is the greatest common factor (GCF) of the numerator and denominator of the rational expression below? (6x+18)/(x^2-x-12)
Answer:
GCF = x+3
Step-by-step explanation:
(6x+18)/(x^2-x-12) = 6 (x+3)/(x^2 +3x - 4x -12)
= 6(x+3)/( x(x+3) - 4(x+3) )
= 6(x+3)/( (x-4)(x+3) )
The greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex] is (x + 3) .
What is greatest common factor (GCF)?The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
According to the question
The rational expression :
[tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]
The greatest common factor (GCF) of the numerator and denominator
Step 1 : We take out factors of numerator
(6x+18) = 6 (x + 3)
Step 2 : Then we take out factors of denominator
[tex](x^2-x-12)[/tex] = x² - (4-3)x - 12
= x² - 4x + 3x - 12
= x (x - 4) + 3(x - 4)
= (x + 3) (x - 4)
Now , The greatest common factor (GCF) of the numerator and denominator is (x + 3) which is present in both .
Hence, the greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex] is (x + 3) .
