one solution of x^2 - 64 = 0 is 8. what is the other solution
Given:
The equation is:
[tex]x^2-64=0[/tex]
One solutions is 8.
To find:
The other solution of the given equation.
Solution:
We have,
[tex]x^2-64=0[/tex]
It can be written as:
[tex]x^2-8^2=0[/tex]
[tex](x-8)(x+8)=0[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
Using zero product property, we get
[tex]x-8=0[/tex] and [tex]x+8=0[/tex]
[tex]x=8[/tex] and [tex]x=-8[/tex]
It is given that the one solutions is 8.
Therefore, the other solution is -8.

Dana is creating a video. Her computer shows that the video is 265.038 seconds long. She writes the length of the video in expanded form. Which expression represents the value of one of the digits in the length of Dana's video?
Options aren't supplied. However, a list of possible answers have been worked out.
Answer:
Kindly check explanation
Step-by-step explanation:
In expanded format :
256.038 can be broken down as :
2 represents 200 ; 2 hundred = 2 * 100
5 represents 5 tens = 50 = 5 * 10
6 represents 6 unit = 6 * 1
0 represents 0 tenths
3 represents 3 hundredths = 3 * 1/100
8 represents 8 thousandths = 8 * 1/1000
The options aren't given, but the answer would be among the values listed above
Using the Pythagorean theorem what is the distance between (5,-3) and (9,1)
Step-by-step explanation:
Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2
=√4^2+4^2
=√16+16
=√32 units
It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2

Step-by-step explanation:
Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.
Which bottle was the better bargain?
Answer:
The 4 pint ketchup bottle was the better bargain.
Step-by-step explanation:
To find which bottle was the better bargain, find which one had the most amount of ketchup in it.
In one quart, there are 2 pints.
Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:
1.25(2)
= 2.5
Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.
So, the 4 pint ketchup bottle was the better bargain.
Find the value of x.
Answer:
x = 4
Step-by-step explanation:
The angle next to (adjacent to) 19x + 3 is 180 degrees less (19x + 3):
180 - (19x + 3)
and the three interior angles of the triangle must sum up to 180 degrees:
11x - 2 + 180 - 19x - 3 + 9x + 1 = 180, or
11x - 2 - 19x - 3 + 9x + 1 = 0
Combining like terms, we get:
x = 4

Answer:
-2x + (-3) = x
x = -1
Step-by-step explanation:
-2x + (-3) = x
add 2x to each side
-3 = 3x
divide each side by 3
-1 = x
f(x) = 3x - 1
Consider the function below. Find f(x) = 32 *find x value*
Answer:
f(32) = 95
Step-by-step explanation:
f(32) = 3(32)-1
f(32) = 96 - 1
f(32) = 95

Kevin needs to buy some cardboard to build a box 11 inches long, 7 inches wide, and 10 inches high. How much cardboard is needed to build the box?
Answer:
770 inches of cardboard is needed to build this box
Step-by-step explanation:
Use the formula for cubes B x W x H
The base of the cube will be 7 inches the length is 11 inches, and the height is 10 inches. Then, we multiply.
7 x 11 x 10 = 770

Jasmine had an average daily balance of $1,608.24 for the last billing cycle, which had 31 days. If her credit cards charges an APR of 22.99%, what would her finance charges be for the last billing cycle?
Answer:
Finance per billing cycle = $ 30.91
Step-by-step explanation:
First, we will calculate the APR for 1 day:
APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)
APR per day = 0.062 % / day
Now, we will calculate the finance per day:
Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)
Finance per day = $0.99/day
Now, we will calculate the finance for one billing cycle:
Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)
Finance per billing cycle = $ 30.91

3. The half-life of Co-60 is 5.3 years. If the initial mass of the sample is 1
kg, how much will remain after 15.9 years.
Answer:
0.125kg
Step-by-step explanation:
an equation can be made from teh problem
f(x)=1(0.5)^(x/5.3)
x is the amount of years
plug in 15.9 for x
f(15.9)=0.125
Suppose A and B are independent events. If P(A) = 0.6 and P(B) = 0.85, what is P(A and B)? A. .34 B. .51 C. .17 D. .68
Answer:
0.51
Step-by-step explanation:
Mathematically, for two individual events;
P(AnB) = P(A) * P(B)
P(A n B) = 0.6 * 0.85 = 0.51
Answer:
.51 (B)
