find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

Can someone please give me a simple explanation on exponential functions? I need to write a one page essay over what it is
Answer:
The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent. A simple example is the function

Answer:
iihi
Step-by-step explanation:
Answer:
h > 2
-------------------------
h < 3
Step-by-step explanation:
5h – 4 > 6
add 4 both sides
5h > 10
divide 5 both sides
h > 2
-------------------------
7h + 11 < 32
subtract 11 both sides
7h < 21
divide 7 both sides
h < 3

Next time, the rabbit from the previous problem start at 10 where on the number line can he be after the same three jumps?
Previous problem : A rabbit started at point 0 and made 3 jumps: a jump of 4 units, then a jump of 2 units, and then a jump of 1 unit. We do not know the direction of either jump. What are all the possible numbers can this rabbit be now?
It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.
What is a number line?A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:
Total distance = 4 units + 2 units + 1 unit
Total distance = 7 units.
Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:
Total distance = 10 units + 7 units
Total distance = 17 units.

Answer: The length of the hypotenuse (c) is 5
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
a & b are the legs (b is the base)
c = hypotenuse
a = 4
b = 3
a² + b² = c²
4² + 3² = c²
16 + 9 = c²
25 = c²
√c² = √25
c = 5
the perimeter of a rectangle is 30 cm. The height is 5 cm . what is the area of that rectangle.
Answer:
Pretty sure its 50
Step-by-step explanation:
if the height is 5, that would be multiplied by 2 because there are two identical sides. From the product, 10, you would need to get to 30, so you add 20. that means the other two identical sides are 10cm. 10x5 (length x width) is equal to 50.
Answer:
[tex]30 = 2 \times l + 2 \times b \\ 30 = 2 \times 5 + 2 \times b \\ 30 = 10 + 2b \\ 30 - 10 = 2b \\ 20 = 2b \\ = 20 \div 2 = 10 \\ area = l \times b \\ 5 \times 10 = 50cm {}^{2} [/tex]
A concert venue has 20 seats in the first row and an 5 additional seats in each successive row. If there are 35 rows of seats then how many people can attend a sold-out show? 3,675 190 2,100
Answer:
3,675 people
Step-by-step explanation:
First row, a = 20
Common difference, d = 5
number of terms, n = 35
Sn = n/2 {2a + (n - 1)d}
= 35/2 {2*20 + (35 - 1)5}
= 35/2 {40 + ( 34)5}
= 17.5(40 + 170)
= 17.5(210)
= 3,675 people
The answer is actually 3675.

cream, including an 8% sales tax.
What was the total cost of all three bowls of ice cream before tax was added?

Answer:
total cost - $3.23 per icecream cone no tax // cost is $9.69 all 3 ice cream cones no tax // solve by multiplying .08 by $3.51. you get .28 // subtract that from $3.51 to solve

Problem 1
To find the y intercept, plug in x = 0 and simplify
f(x) = (x-2)(x+4)
f(0) = (0-2)(0+4)
f(0) = (-2)*(4)
f(0) = -8
We have x = 0 pair up with y = -8
The y intercept is (0,-8)
Answer: Choice D
========================================
Problem 2
(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.
The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.
Answer: C) Parabola opens upward
========================================
Problem 3
Answers:
A = h(x)B = f(x)C = g(x)Explanation:
Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).
Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.

7x+13 = 48
7x = 35
x = 5
Answer:
D. 5
Step-by-step explanation:
The angle should equal 48 degrees as it is congruent to the other angle labeled as 48 degrees.
So, we get the equation 7x + 13 = 48
Subtract 13 from both sides.
7x + 13 - 13 = 7x
48 - 13 = 35
We get 7x = 35
Divide by 7 on both sides.
7x / 7 = x
35 / 7 = 5
We get x = 5.

Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second
