Use the Pythagoream theorm Show your work
Answer:
c=13
Step-by-step explanation:
The equation to solve the Pythagorean Theorm looks like this-
a²+b²=c²
So, lets use it to find the hypotenuse-
5²+12²=c²
(5*5)+(12*12)=(c*c)
25+144=c²
(25+144=169)
Now we have to find the square root of 169 (just put [tex]\sqrt{169[/tex] into the calculator)
c=13

What is the sum of x^
2 – 3x + 7 and 3x² + 5x – 9?
1) 4x² – 8x + 2
2) 4x² + 2x + 16
3) 4x2 – 2x – 2
4) 4x² + 2x - 2
Answer:
4. [tex]4x^{2} +2x-2[/tex]
Step-by-step explanation:
To add these two equations together, you have to combine like terms.
1. [tex]x^{2} +3x^{2} = 4x^{2}[/tex]
2. [tex](-3x)+5x = 2x[/tex]
3. 7 - 9 = -2
Then you just combine all of these terms together into one equation and you have your answer.
Hope this helped!

A hot air balloon descends 38.5 meters in 22 seconds. If the balloon continues to descend at this rate, how long will it take to descend 125 meters?
A. 25.25 seconds
B. 86.5 seconds
C. 71.43 seconds
D. 218.75 seconds
Answer:
C. 71.43 seconds
Step-by-step explanation:
Given data
Distance= 38.5m
time= 22 seconds
speed= 38.5/22
speed= 1.75 m/s
given that distance = 125meters
t= 125/1.75
t= 71.4 seconds

PLS HELP ME IM BEGGIN YOU THIS IS DUE IN 5 MIN
Answer:
3/10
Step-by-step explanation:
Let's assume;
30 ml of Orange Juice + 45 ml of Apple Juice + 25 ml of Coconut milk = 1 glass of Cocktail
30 ml : 45 ml : 25 ml = 1
30 + 45 + 25 = 100 ml = 1 glass of Cocktail
Orange juice proportion = Amount of Orange Juice in ml ÷ 1 glass of Cocktail in ml
Orange Juice proportion = 30 ml ÷ 100 ml
= 3/10
Answer:
In a fruit cocktail, for every 30 ml of orange juice you need 45 ml of apple juice and 25 ml of coconut milk.
Step-by-step explanation: Hope this is right I think there is 3/10 of Orange juice
Total Contents: 25 +30+45+100
Proportion of apple juice:
30/100
3/10

can someone help me
Step-by-step explanation:
we need to use pythagoras's theorem (reversed) in this situation. We know the hypotenuse and the lower line, so we can find the upright one. That will be the value of AD.
so we use 81 (9 squared) and 144 (12 squared)
let x be the upright line's length
144-81=x squared
63=x squared
find the square root of 63 and you can have your answer
Im not gonna do that for you because that's pretty easy
Why do we use 'average' in our daily life?
Answer:
The term average is used frequently in everyday life to express an amount that is typical for a group of people or things. ... Averages are useful because they: summarise a large amount of data into a single value; and. indicate that there is some variability around this single value within the original data.
Step-by-step explanation:
One of the roots of equation x^(2)-(3p-4)x+11p-5=0 is 8. Find the other root. Find the value of p.
Answer:
Other root is 9 and p = 7.
Step-by-step explanation:
x^(2) - (3p-4)x + 11p-5 = 0 , x = 8.
Let the other root be A, then using the formula for the product and sum of the roots of a quadratic equation:
8* A = 11p - 5
8 + A = -(-(3p - 4))
8 + A = -(-3p + 4)
8 + A = 3p - 4
A = 3p - 12.
Multiply this last equation by 8:
8A = 24p - 96
Now subtract the first equation from this:
8A - 8A = 24p - 11p - 96- (-5)
0 = 13p - 91
13p - 91 = 0
p = 91/13 = 7
and A = 3(7) - 12
= 9.
Answer:
Other root 9, p is 7

A given set of data is said to have a greater spread if it covers a large scale/area. Since the data set 3 only covers a small portion of a wide spectrum it is said to have a smaller spread when in comparison with data set 4 which has a greater spread as it covers a larger scale/spectrum.
▪︎Therefore, Data set 4 has a greater spread.
○=> Solution (8) :Lower quartile of a data set is said to be the median of the lower half of the data set.
Lower quartile of this data set :
[tex] = \tt \frac{50 + 60}{2} [/tex]
[tex] =\tt \frac{110}{2} [/tex]
[tex]\color{plum} =\tt 55[/tex]
Thus, the lower quartile of this data set = 55
Median is said to be the middle element of a data set.
The median of this data set = 80
Upper quartile of a data set is said to be the median of the upper half of a given data set.
Upper quartile of this data set :
[tex] =\tt \frac{110 + 100}{2} [/tex]
[tex] =\tt \frac{210}{2} [/tex]
[tex]\color{plum} = \tt105[/tex]
Thus, the upper quartile of this data set = 105
Therefore :▪︎Lower quartile of this data set = 55
▪︎Upper quartile of this data set = 105
▪︎Median of this data set = 80
what is the y intercept of 13,-6
Answer:
More info needed
Step-by-step explanation:
If 13,-6 represents (13,-6), this is a point. The y coordinate is -6, but there would be no y intercept since a single point won't cross the y axis.
The length, in millimeters of each side of a square shaped electronic chip is a rational number. What statement is true about the length of the diagonal of the chip
Answer:
The diagonal is irrational because it is a product of a rational and an irrational number
Step-by-step explanation:
The options are not given. However, the question is still answerable.
Given
Shape: Square
Length: Rational
Since the side length is said to be rational, I'll answer the question based on whether the diagonal is rational or not.
Having said that:
The diagonal (d) of a square with side length (l) is calculated using Pythagoras theorem.
[tex]d^2 = l^2 + l^2[/tex]
[tex]d^2 = 2l^2[/tex]
Take positive square root of both sides
[tex]d = \sqrt{2l^2}[/tex]
Split:
[tex]d = \sqrt{2} * \sqrt{l^2}[/tex]
[tex]d = \sqrt{2} *l[/tex]
Recall that the side length (l) is rational.
However, [tex]\sqrt 2[/tex] is irrational.
So, the product of l and [tex]\sqrt 2[/tex] will be irrational
Hence:
The diagonal is irrational
Express in the form 1:n
3:12
Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4

Total marks: 4
Answer:
turning point: (-3 , -16)

(0)² + 0*a + b = -7 b= -7
(7)² + 7*a - 7 = 0 7a = 42 a = 6
