Answer:
30
Step-by-step explanation:
Given the radical values;
√1000
= √100 * √10
= 10√10
= 10 (3.1623)
= 31.623
Converting to nearest 10,
= 30
Hence the value to the nearest 10 is 30

Answer:
Step-by-step explanation:
Set up a right triangle to reflect the tangent ratio. Tangent is equal to the side opposite the reference angle over the side adjacent to the reference angle. If tangent is 4/3, then the side opposite the reference angle is 4 in length and the side adjacent is 3 in length. The reference angle, just for clarification, is the base angle that is not the right angle. So we have a right triangle with a height of 4 and a base of 3. We need the sin ratio from that. The sin ratio by definition is the side opposite the reference angle over the hypotenuse. But we don't have the hypotenuse. We have to solve for it using Pythagorean's Theorem.
[tex]h^2=4^2+3^2[/tex] and
[tex]h^2=16+9[/tex] and
[tex]h^2=25[/tex] so
h = 5. Now we find the sin ratio to be 4/5 (the side opposite the reference angle over the hypotenuse).

Y=-1/3x+6 and x=-6 find the solution to the system
Answer:
(- 6, 8 )
Step-by-step explanation:
Given the 2 equations
y = - [tex]\frac{1}{3}[/tex] x + 6 → (1)
x = - 6 → (2)
Substitute x = - 6 into (1) and evaluate for y
y = - [tex]\frac{1}{3}[/tex] × - 6 + 6 = 2 + 6 = 8
solution is (- 6, 8 )

Answer:
Mean=85.5
Median=82
Mode=82
Range=25
Please would you mind marking me as the brainliest:)
Answer:
Mean: 85
Median: 82
Mode: 82
Range: 25
Step-by-step explanation:
The mean is the average of all of the numbers. You add all of the numbers together and then divide by the total amount of number you have. In this case you have 8 scores. So you add all the scores together, and then divide by 8:
82 + 78 + 82 + 80 + 100 + 96 + 75 + 91 = 684
684/8 = 85.5
So 85 is the mean.
The median is the number that is in the middle of all of the numbers listed. To do this, first list the numbers in order:
75, 78, 80, 82, 82, 91, 96, 100
The two numbers in the middle are both 82. So, 82 is the median.
The mode is the number that appears the most. In this problem, you can see that the number 82 appears twice. So 82 is the mode.
The range is the highest number minus the smallest number. Here, the highest number is 100. The smallest number is 75. So,
100 - 75 = 25
25 is the range.

Answer:
C) {48, 55, 73}
Step-by-step explanation:
In general, you see which sets of numbers satisfy the Pythagorean theorem. The tedium can be relieved slightly by letting a spreadsheet do the calculations.
The attachment shows us that triangle C is a right triangle.

What is the average rate of change for this quadratic function for the interval
from x = 1 to x = 3?
O A. -8
B.-4
O O
C. 8
O D. 4
==========================================================
Explanation:
The table says that when x = 1, the output is y = -2.
So the point (1, -2) is on the parabola.
The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.
Find the slope of the line through those two points. The slope here is the same as the average rate of change.
m = (y2 - y1)/(x2 - x1)
m = (-10 - (-2))/(3 - 1)
m = (-10 + 2)/(3 - 1)
m = -8/2
m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.
Find the equation of a line that passes through the point (3,6)
with slope 2.
Answer:
y = 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 6) into the partial equation
6 = 6 + c ⇒ c = 6 - 6 = 0
y = 2x ← equation of line
The equation of line that passes through the point (3,6) with slope 2 is;
⇒ y = 2x
Given that;
The point is (3, 6)
The slope of line = 2
We have to find the equation of a line that passes through the point (3,6) with slope 2.
What is equation of line?
The equation of line that passes through the point (x₁, y₁) with slope m is;
y - y₁ = m (x - x₁)
The point is (3, 6)
The slope of line = 2
The equation of line that passes through the point (x₁, y₁) = (3,6)
with slope(m) = 2 is;
y - y₁ = m (x - x₁)
y - 6 = 2 (x - 3)
y - 6 = 2x - 6
Add 6 on both sides;
y = 2x
Hence, The equation of line that passes through the point (3,6) with slope(m) 2 is;
⇒ y = 2x

Answer:
19.82%
Step-by-step explanation:
Add all members that want weight lifting
47 + 21 + 14 + 29 = 111
111 / total members
111 / 560 = 0.1982
0.1982 * 100% = 19.82%
Answer:
33% of 100% of men
Step-by-step explanation:
Add 50 + 19 + 24 = 93
(amount of men doing anything other than lifting) 93÷140= 0.664 (about 66%)
(amount of men lifting) 47÷140= 0.335 (about 33-34%)
So 33% out of 100% of men would lift.

Can someone help me with this question and help me find out what the "a" does in the problem y=a(x-h)^(2)+k
Answer:
See below (and attached file)
Step-by-step explanation:
The value of [tex]a[/tex] in the equation [tex]y=a(x-h)^2+k[/tex] represents how much a vertical parabola will stretch or compress, as well as whether it opens upward or downward:
If [tex]0<|a|<1[/tex], it is a horizontal stretch
If [tex]|a|>1[/tex], it is a horizontal compression
If [tex]a<0[/tex], the parabola opens downward
If [tex]a>0[/tex], the parabola opens upward
The file attached shows a graph with different examples of what happens to a parabola when the value of [tex]a[/tex] changes.
