Answer:
A (first graph)
Step-by-step explanation:
Since the equation is negative, the graph will be opening down, and since it is -1, turned into +1, it will shift to the right by one unit.
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.

Each side of a square name tag is 7 centimeters long. What is the name tag's area?
Answer:
49 cm²
Step-by-step explanation:
The area for a square is Area = length x width, and if the square name tag is 7cm long on "each side", that means that both the length and the width are 7cm.
Plug this into the formula to get A = 7cm x 7cm.
This can be simplified to A = 49cm².
Answer: 49 cm^2
Step-by-step explanation:
7 x 7 = 49
This circle is circumscribed about quadrilateral ABCD. What is the value of x?
Answer:
The value of x is 56°
Step-by-step explanation:
Given that opposite angles in a cyclic quadrilateral is add up to 180°. So in order to find x, you have to write an expression in terms of x :
[tex]97 + x + 27 = 180[/tex]
[tex]x + 124 = 180[/tex]
Next you have to solve it by substracting 124 to both sides :
[tex]x + 124 - 124 = 180 - 124[/tex]
[tex]x = 56[/tex]

Example:
I think the Pythagorean Theorem relates to...
Answer:
The Pythagorean theorem works only on right triangles. Also it is used to find the hypotenuse when you know 2 other sides.
Step-by-step explanation:
Answer: The Pythagorean Theorem is a formula used to find the hypotenuse (the value of C2).
Step-by-step explanation: That formula is A2 + B2 = C2. Right Triangles are the only triangles that relate to the Pythagorean Theorem.

(SAT Prep) Find the value of x in each of the following exercises:
THANKS!!
Answer:
x is 24 degrees
Answer:
x = 24
Step-by-step explanation:
I'm 8 years old and I know how to do this.
The sum of interior angles of a quadrilateral is 360°
The sum of a supplementary angle is 180°
180 - 111 = 69
94 + 41 + 69 + a = 360
204 + a = 360
a = 156
156 + x = 180
x = 24

Math question down below
Answer:
B
Step-by-step explanation:
I need help understanding how to solve this please ASAP!!!!
Answer:
17 cm
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 =c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 = c
Answer:
The hypotenuse is 17cm
Step-by-step explanation:
Pythagoras theorem is : [tex]a^{2} +b^{2} =c^{2}[/tex]
To work out the hypotenuse of this triangle you would first need to know Pythagoras theorem. The theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. A and B are the 2 lengths given in this question and c is the hypotenuse.
The first step in working out the hypotenuse is to square the base of 8, this gives you 64.
Then you would need to square the height of 15, this gives you 225. This is because we are substituting the values into a and b.
Then the next step is to add the values of 64 and 225, this gives you 289.
The final step is to root the value of 289, which gives you 17cm. This is because as c is the hypotenuse while the value worked out is c squared and so to work out c you would have to root it.
1) Square the base of 8cm.
[tex]8^{2} =64[/tex]
2) Square the height of 15cm.
[tex]15^{2} =225[/tex]
3) Add 64 and 225.
[tex]64+225=289[/tex]
4) Root the value of 289.
[tex]\sqrt{289}= 17cm[/tex]

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) .

Answer:
2:4 means one part is 2/(2+4)=1/3 of AB and the other part is 2/3 of AB
Step-by-step explanation:
Add 1/3 of the distance from -2 to 4. (1/3)(4+2)=2. -2+2=0 The x coordinate is 0
Subtract 1/3 of the distance from 6 to -6, (1/3)6+6)=4 6-4=2 The y coordinate is 2
The point is (0,2)
Check the answer
distance from (-2,6) to (0,2) is square root of (-2)^2 + (4)^2 = sqr20 = 2(5)^2
distance from (0,2) to (4,-6) is square root of (4)^2 +(8)^2 = sqr80 = 4(5)^2
First distance is half the 2nd distance, so the point divides AB into 2 parts in a ratio of 2:4
