Answer:
First option is the correct answer
[tex]m= 14 \sqrt 2, \: n = 14[/tex]
Step-by-step explanation:
Hope it helps you in your learning process.
Given is a 45°-45°-90° triangle.
Measure of sides n and 14 are opposite to 45° degree angles.
Therefore, they are equal.
So, n = 14
[tex] 14 = \frac{1}{\sqrt 2}\times m[/tex]
[tex] 14 \sqrt 2=m[/tex]
can you please show work for 5x/9=x/6+7
Step-by-step explanation:
Please refer to the attachment
Answer:
x = 18
Step-by-step explanation:
5x/9 = x/6 + 7
multiply both sides by 9
5x = 9x/6 + 63
multiply both sides by 6
30x = 9x + 378
subtract 9x from each side
21x = 378
divide both sides by 21
x = 18
check by substituting 18 for x:
5(18)/9 = 18/6 + 7
5(2) = 3 + 7

Find the domain and range of the function below
work out the size angle DEF
Answer:
Step-by-step explanation:
Here, we want to get the value of angle DEF
we have this as ;
Angle DEF = 1/2 * DOF
1/2 * 150 = 75
This is because angle at the center is twice the angle at the circumference

Actually Welcome to the Concept of the Functions.
Since, the above function is a square root function, we must always keep it's domain as Positive Real numbers, such that it will not went to the imaginary axis, hence
D: R+
Range, for range we equate it to 0 ,
hence we get as,
R: x belong from 0 to positive Infinite
As, x---> infinite, f(x) ---> - infinite
As, x----> 0 , f(x) -----> 0
increasing interval, we have to differentiate it, we get as
-4 to 0
Decreasing interval is 0 to infinite
angle A = 18° and angle B = 25°. Find angle C.
Answer: Angle C: 137 degrees
Step-by-step explanation:
A+B+C=180
18+25+C=180
C=137
Step-by-step explanation:
triangle add U to 180
18 + 25 = 43
180 - 43 = 137 degree is c
Solve two fifths minus one seventh equals blank.
Answer:
9/35.............,..........
Answer:
1/5
Step-by-step explanation:
2/5 - 1/7 = ???
find the least common denominator!
45 would be the least common demoninator!
so...
2 (7) / 5(7) - 1 (5) / 7 (5) = ?
14/ 45 - 5 /45 = ?
14 - 5 = 9
9/45. Simplify!
9/45 divide 9 from both sides
9/9 / 45/9
= 1/5, one fifths is your answer!
Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

a paper balloon costs php7.50 what is the cost if i buy 6balloons?
Answer:
45
Step-by-step explanation:
Please help......... please
Answer:
Step-by-step explanation:
2x + 4 = 2(x + 2)
[tex]Area = \frac{1}{2}*b*h\\\\=\frac{1}{2}*(2x-1)(2x + 4)\\\\\\= \frac{1}{2}*(2x - 1)*2*(x + 2)\\\\= (2x -1)(x+ 2)[/tex]
= 2x *x + 2x* 2 + x*(-1) + 2*(-1)
= 2x² + 4x - x - 2
= 2x² + 3x - 2

A different camera is selling for $7.50 off the regular price. It was discounted 15%. What was the original price of the camera?
A)$112.50
B)$75.00
C)$50.00
D)$45.00
Answer:
C) $50.00
Step-by-step explanation:
$7.50 is the 15% discount
1% of the original price would be ($7.50 / 15)=0.50
100% of the original price would be 100 x 0.50 = $50.00
Find zeros and y intercept of each function algebraically f(x)=x^3-10x^2+24x
Answer:
The zeros are 0, 4, 6.
The y-intercept is 0.
Step-by-step explanation:
f(x) = x^3 - 10x^2 + 24x
x^3 - 10x^2 + 24x = 0
x(x^2 - 10x + 24) = 0
x(x - 4)(x - 6) = 0
x = 0 or x - 4 = 0 or x - 6 = 0
x = 0 or x = 4 or x = 6
y-intercept:
Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.
You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).
Let x = 0.
f(0) = 0^3 - 10(0^2) + 24(0)
f(0) = 0
y-intercept: 0
