What is the value of "w" ?
Answer:
w = [tex]\sqrt{147}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
w² + 7² = 14²
w² + 49 = 196 ( subtract 49 from both sides )
w² = 147 ( take the square root of both sides )
w = [tex]\sqrt{147}[/tex]

(f+g)(2)=
(f-g)(2)=
(fg)(2)=
Answer:
(f + g)(2) = 16
(f - g)(2) = 0
(fg)(2) = 64
Step-by-step explanation:
f(2) = 8 g(2) = 8
(f + g)(2) = f(2) + g(2) = 8 + 8 = 16
(f - g)(2) = f(2) - g(2) = 8 - 8 = 0
(fg)(2) = f(2)g(2) = 8(8) = 64

What is the value, to the nearest tenth, of 15 x 3 - 12 x 2 when x = 2.5
Answer:
159.4
Step-by-step explanation:
I'm assuming that it's supposed to be 15x^3-12x^2 because when you copy and paste the "^" gets cut out
15*2.5^3 - 12*2.5^2 = 234.375 - 75 = 159.375
rounded is 159.4
After t seconds a ball thrown in the air from ground level reaches a given
height (h) in feet. Given the equation h = -1612 + 144 + 100 at what time does the
ball reach 100 feet?
Answer:
9 sec.
Step-by-step explanation:
I think you wrote the equations incorrectly. It probably is
[tex]h = -16t^{2} + 144t + 100[/tex]
If that is true, then [tex]100 = -16t^{2} + 144t + 100[/tex]
0 = -16[tex]t^{2}[/tex] + 144t
-16t(t - 9) = 0
t = 0 or t = 9

What are Trignometric ratios ?The ratios of the sides of a right triangle are called trigonometric ratios.
Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
sin = Perpendicular/ Hypotenuse
Cos = Base / Hypotenuse
tan = Perpendicular/Base
In the figure attached with the answer we can see that in Triangle ABC ,
tan 50.1 = x / 5
5(tan 50.1) = x
Therefore x is approximately equal to 6.

I'm not too sure what you mean but since there was no image I tried to look up how to tell if angles are corresponding based on angle degree and the most I got was the angles will be equal but only if there is a transversal cur but none of the answers equal each other
Step-by-step explanation:
so what advice I can give you is corresponding angles are usually the same degree but on a different level. like on the first parallel line there is an angle and on the second (or whatever) there is another angle (on the same side of the first) -meaning they will both be on the right or the left- and yeah there you go

What is equivalent ratio of 5:8:4 and explain how u got it
this is example
So, first we need to write the given ratio as fraction,
= 8/18
= (8 × 2)/(18 × 2)
= 16/36
= 16 : 36 (one equivalent ratio),
So, 16 : 36 is an equivalent ratio of 8 : 18.
Now we will find another equivalent ratio of 8 : 18 by using division.
Similarly, first we need to write the given ratio as fraction,
= 8/18
= (8 ÷ 2)/(18 ÷ 2)
= 4/9
= 4 : 9 (another equivalent ratio)
So, 4 : 9 is an equivalent ratio of 8 : 18.
Therefore, the two equivalent ratios of 8 : 18 are 16 : 36 and 4 : 9.
2. Frame two equivalent ratios of 4 : 5.
Solution:
To find two equivalent ratios of 4 : 5 we need to apply multiplication method only to get the answer in integer form.
First we need to write the given ratio as fraction,
= 4/5
= (4 × 2)/(5 × 2)
= 8/10
= 8 : 10 is one equivalent ratio,
Similarly again, we need to write the given ratio 4 : 5 as fraction to get another equivalent ratio;
= 4/5
= (4 × 3)/(5 × 3)
= 12/15 is another equivalent ratio
Therefore, the two equivalent ratios of 4 : 5 are 8 : 10 and 12 : 15.
Note: In this question we can’t apply division method to get the answer in integer form because the G.C.F. of 4 and 5 is 1. That means, 4 and 5 cannot be divisible by any other number except 1.
The two equivalent ratios of 5:8:4 are 8: 10 and 12: 15.
What is a fraction?The fraction is defined as the division of the whole part into an equal number of parts. In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
First, we need to write the given ratio as a fraction,
F= 8/18
F= (8 × 2)/(18 × 2)
F= 16/36
F= 16 : 36 (one equivalent ratio),
16: 36 is an equivalent ratio of 8: 18.
Find another equivalent ratio of 8: 18 by using division. Similarly, first, we need to write the given ratio as a fraction,
F= 8/18
F= (8 ÷ 2)/(18 ÷ 2)
F= 4/9
F= 4 : 9 (another equivalent ratio)
4: 9 is an equivalent ratio of 8: 18.
Therefore, the two equivalent ratios of 5:8:4 are 16: 36 and 4: 9.

Answer:
161.56 ft^2
Step-by-step explanation:
base area = (leg 1 x leg 2)/2 = (5 x 5)/2 = 25/2 = 12.5 ft^2
base perimeter = 5 + 5 + 7.07 = 17.07 ft
lateral surface = (perimeter x height) = 17.07 x 8 = 136.56 ft^2
surface area = base area x 2 + lateral surface = (12.5 x 2) + 136.56 = 161.56 ft^2

Tony will spend at most $27 on gifts. So far, he has spent $14. What are the possible additional amounts he will spend?
Use c for the additional amount (in dollars) Tony will spend.
Write your answer as an inequality solved for c.
Answer:
Inequaltiy: 27 ≤ 14+c
Final answer: 13 ≤ c
Step-by-step explanation:
Well tony spent at most 27 dollars.
He spent 14 already and he can‘t get past 27 dollars but he can spend exactly 27 or even less.
So 27 ≤ 14+c
You would like to lease a car worth $61,815 for a three-year period. The leasing company told you that after three years, the car would have a residual value of $44,999. What percentage represents the residual value of your leased car?
Answer:
72.8%
Step-by-step explanation:
Percentage residual value = (residual value / worth of the car) x 100
(44,999 / 61,815) X 100 = 72.8%
A pro-athlete is offered an eight-year
contract with a starting salary of
$400,000. She will receive an increase
of so each year.
The athlete's salary each year forms a geometric
sequence
What is a1, in thousands?
What is r?
Answer:
400
1.05
Step-by-step explanation:
The athlete should take the second offer.
It is given by the formula,
A = P(1+r)ⁿ
where A is the value after n period of time, P is the initial amount, and,
r is the rate of increment or decrement.
Now, Total amount = $400,000(1+5%)⁷
= $400,000(1+0.05)⁷
= $400,000(1.4071)
= $562840.17
Now, the total amount that the pro-athlete will get in 8 years is,
Total amount = $425,000(1+4%)⁷
= $425,000(1+0.04)⁷
= $425,000(1.3159)
= $559,271
Since the total amount that the athlete will get in the next 8 years is more for the second offer, the athlete should take the second offer.
