Answer:
4/3
Step-by-step explanation:
GH =√90²-72²=
√8100-5184=
√2916= 54
so, tan (H) = 72/54 = 4/3
⁴/3 is a required answer.
Answer:
Solution given:
FG=72
FH=90
By using Pythagoras law
GH=[tex]\sqrt{90²-72²}=54[/tex]
Step-by-step explanation:

find the centre of the circle 4x^2+4y^2+16x- 24y-52=0
Answers
Answer:
(- 2, 3 )
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Given
4x² + 4y² + 16x - 24y - 52 = 0 ( divide through by 4 )
x² + y² + 4x - 6y - 13 = 0 ← add 13 to both sides and rearrange terms on left side
x² + 4x + y² - 6y = 13
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(2)x + 4 + y² + 2(- 3)y + 9 = 13 + 4 + 9
(x + 2)² + (y - 3)² = 26 ← in standard form
with centre (- 2, 3 )
Answer:
Centre at [tex](-2,3)[/tex].
Step-by-step explanation:
Use the general formula for a circle to answer this question. The general formula is :
[tex](x-a)^2+(y-b)^2=r^2[/tex], where [tex](a,b)[/tex]is the centre of the circle and [tex]r[/tex] is the radius of the circle.
We have to get the equation we've been given into the general form. We can do this by completing the square as follows:
[tex]4x^2+16x+4y^2-24y-52=0[/tex] -Group like terms together.
[tex]x^2+4x+y^2-6y-13=0[/tex] - Divide by common factor of 4.
[tex](x+2)^2+(y-3)^2=26[/tex] - Complete the square and move constant to the other sides.
Now that it's in the general form we can find the centre. Centre at [tex](-2,3)[/tex].

Answer:
2571.14 m^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The diameter is 17 so the radius is 1/2 of the diameter or 17/2 =8.5
V = 4/3 (3.14) (8.5)^3
= 2571.13666
Rounding to the nearest hundredth
= 2571.14 m^3
Answer: 2571.14
=================================================
Work Shown:
V = (4/3)*pi*r^3
V = (4/3)*3.14*(8.5)^3
V = 2571.13666666667 which is approximate
V = 2571.14
-------------
Notes:
The units for the volume are in cubic meters, or m^3. Think of a 1 m by 1 m by 1 m block, the volume of which is 1*1*1 = 1 m^3.The diameter is 17 meters, half of which is 17/2 = 8.5 meters. So the radius is r = 8.5In the second to last line, the '6's go on forever. It's only due to rounding is why that '7' shows up.The answer above is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate volume. However, your teacher wants you to use pi = 3.14

What is the difference between the highest percent of votes received by student in the lowest percent of votes received by a student? Round to the nearest whole number if needed.
A. 20%
B. 8%
C. 35%
D. 15%
Answers
Answer:
A) 20%
Step-by-step explanation:
The total votes are:
40 + 70 + 60 + 90 = 260
Rebecca has the highest percent of votes which is 90 votes. To find the %:
90/260 ≈ 34.62%
Amy has the lowest percent of votes which is 40 votes.
40/260 ≈ 15.38%
Finding the difference:
34.62 - 15.38
19.24
So, it's around 20%

why is probability limited to numbers between 0 and 1
Answers
Answer:
Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.
Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.
Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case

A factory inspector found 3 defective microchips out of a total of 750
microchips made. Which proportion can be used to predict the number of
defects, x, in a batch of 10,000 microchips?
Answers
Answer:
Option B
Step-by-step explanation:
Proportion of number of defective pieces to the number of microchips in a batch can be represented by the ratio = [tex]\frac{\text{Number of microchips not in good condition}}{\text{Total numbers of microchips}}[/tex]
If 3 microchips are defective in a batch of 750 microchips,
Proportion = [tex]\frac{3}{750}[/tex]
If 'x' chips are defective in a batch of 10000 microchips,
Proportion = [tex]\frac{x}{10000}[/tex]
If both the proportions are equal,
[tex]\frac{3}{750}=\frac{x}{10000}[/tex]
Therefore, Option B will be the answer.

List the next three numbers for the sequence:
34, 102, 408, 2040, ...
Answers
Answer:
12240
85680
685440
Step-by-step explanation:
We know that the sequence is growing rapidly
To see how rapidly divide the second term by the first term
102/34 =3
Check the third term divided by the second term
408/102 =4
Check the fourth term divided by the third term
2040/408=5
To get the second term, multiply by 3, to get the third term multiply by 4
to get the fourth term multiply by 5
to get the nth term multiply by (n+1)
The 5th term would be multiplied by 6
2040 *6 =12240
The 6th term by 7
12240*7=85680
The 7th term by 8
85680*8=685440
The varsity soccer team has 20 players. Three of the players are trained to be goalies while the remaining 17 can play any position. Only 11 of the players can be on the field at once.
Answers
Answer:
A.) combination
B.) 167,960 ways
C.) 58,344 ways
Step-by-step explanation:
A.)
Choosing 11 players out of 20 available is a cbinationtuon problem simply because the order of choice of the 11 players does not matter on this scenario.
B.)
Here, the coach wants to select her 11 from all available 20:
We apply the combination formula :
nCr ; where ; n = 20 ; selection, r = 11
nCr = n! / (n-r)!r!
20C11 = 20! / 9!11!
20C11 = 167,960
C.)
1 goalie 10 players
1 goalie is selected from the 3 available goalies AND 10 players from the 17 available players :
This gives :
3C1 * 17C10
3C1 = 3
17C10 = 19,448
3C1 * 17C10 = 3 * 19448
= 58,344 ways
