Can someone please help me with my homework its due in two hours!!!!!! Please i need it done soon.
Answer:
see explanation
Step-by-step explanation:
so, when a=-3, c is -20. now, to find b when a is -3, plug a (which is -3) into the equation b=4a-5 to get b=-17. so b=-17, c=-20. b is obviously larger (remember the negative sign)
when c is 21, a is 5. plug numbers in to get b=15.
when a is 6, there is no clear value for c, so i'd guess undefined. b however is 19
we can plot the line and the points, for problem 4 and all points above the line means that c is greater than b, and when below it's less than. doing this we get when a is 12, when a is 0, and when a is 5. hope this was clear
what’s the slope?? Please help
Answer:
Slope of the line represented by the table is 2.5.
Step-by-step explanation:
For a linear function,
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (0, 12) and (-2, 7) will be,
Slope = [tex]\frac{12-7}{0-(-2)}[/tex]
= [tex]\frac{5}{2}[/tex]
= 2.5
Therefore, slope of the line represented by the table is 2.5.
juan utiliza su bicicleta para hacer deporte cada dia recorre 10 kilometros a la mañana y 5 kilometros a la tarde ¿cuantos kilometros recorre e total al cabo de 5dias?
Answer:
75 kilómetros.
Step-by-step explanation:
Dado que Juan utiliza su bicicleta para hacer deporte, y cada día recorre 10 kilómetros a la mañana y 5 kilómetros a la tarde, para determinar cuántos kilómetros recorre en total al cabo de 5 días se debe realizar el siguiente cálculo:
(10 + 5) x 5 = X
15 x 5 = X
75 = X
Por lo tanto, Juan recorre 75 kilómetros al cabo de 5 días.
What is the area of a square that has a perimeter of 16?
Step-by-step explanation:
If the figure is a square with a perimeter of 16 inches, then each side of the square is 4 inch in length. Area is found by multiplying the length x the width. For a square, the length and width are the same. A = 16 sq

what I the Tangent of the 30° angle and the Tangent of the 60° angle?
Answer:
[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]
[tex]\tan(60) = \sqrt 3[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find [tex]\tan(30)[/tex] and [tex]\tan(60)[/tex]
The tangent of an angle is calculated as:
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan(30) = \frac{b}{a}[/tex]
This gives:
[tex]\tan(30) = \frac{3}{3\sqrt 3}[/tex]
3 cancels out
[tex]\tan(30) = \frac{1}{\sqrt 3}[/tex]
Rationalize
[tex]\tan(30) = \frac{1}{\sqrt 3} * \frac{\sqrt 3}{\sqrt 3}[/tex]
[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]
Similarly;
[tex]\tan(60) = \frac{a}{b}[/tex]
This gives:
[tex]\tan(60) = \frac{3\sqrt 3}{3}[/tex]
3 cancels out
[tex]\tan(60) = \sqrt 3[/tex]

Answer:
282.7 in³
Step-by-step explanation:
The solid is a cylinder
Volume of the cylinder = πr²h
Where,
radius (r) = 3 in.
height (h) = 10 in
Volume = π*3²*10
= π*9*10
= π*90
= 282.743339 ≈ 282.7 in³ (nearest tenth)

When you see average rate of change what should you automatically think of
Answer:
Steady rate
Step-by-step explanation:
It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

Three methods for teaching mathematics to first graders are to be compared. Ten students are
randomly assigned to each of the methods, and the score on a quiz is recorded. What are the
response and treatment for this experiment?
Answer: The three methods are the treatments and the response is the score achieved on the quiz.
Step-by-step explanation:
The three techniques are the treatments, and the results are the final score.
what is response variable in the experiment?
The researcher predicts that a variable will change if the controlled variable changes; this variable is known as a responsive variable. A dependent variable is another name for a responsive variable.
Solution:
Three methods are assigned for teaching mathematics.
Randomly ten students are assigned to each of the method.
There scores are then recorded on a quiz.
It is clear that the response will be the score card of the students either scoring high marks or not being able to clear it.
And the treatments are three for if the student is not able to understand any of the method.
Hence the three methods serve as treatments, and the outcomes determine the final grade.

Daniel is constructing boxes in the shape of triangular prism. How much cardboard is needed to make each box
Answer:
Area of cardboard required = 468 cm²
Step-by-step explanation:
Area of the cardboard required = Surface area of the triangular prism
Surface area of the triangular prism = Area of the lateral sides + Area of the triangular sides
Area of the one triangular side = [tex]\frac{1}{2}(\text{Base)}(\text{Height})[/tex]
= [tex]\frac{1}{2}(12)(9)[/tex]
= 54 cm²
Area of lateral sides = Perimeter of the triangular base × Height
Perimeter of the triangular base = 9 + 12 + 15
= 36 cm
Now area of the lateral sides = (36) × 10
= 360 cm²
Surface area of the prism = 360 + 2(54)
= 360 + 108
= 468 cm²
Therefore, area of cardboard required for each box = 468 cm²

I don’t know the answer
Answer:
(a+b) (a-b) =a^2 - b^2
In this question a=2, b=square root of 5
So 2*2=4 square root of 5 times square root of 5 is 5
4-5=-1
Answer:
I believe the answer is -1.
Step-by-step explanation:
So I distributed,
2 x 2 = 4
[tex]-\sqrt{5}[/tex] x 2 = [tex]-2\sqrt{5}[/tex]
[tex]\sqrt{5}[/tex] x 2 = [tex]2\sqrt{5}[/tex]
[tex]\sqrt{5}[/tex] x [tex]-\sqrt{5}[/tex] = -5
4 [tex]-2\sqrt{5}[/tex] + [tex]2\sqrt{5}[/tex] - 5 = ?
the radicals cancel out and 4 -5 = -1

A Peregrine Falcon took
only 9 seconds to dive
801 meters. What was
the average speed of
the falcon?
Answer:
89 meters per second.
Step-by-step explanation:
That is quite fast!
First, we are given that in 9 sec our falcon has flown 801 meters, let's write an equation for that:
9s = 801
So in order to get s, we divide each side by 9.
Solve!
s = 801/9
s = 89

Solve for x, then
find the
measurement of
the tangents.
Here, as the tangents are given above in variable length with radius of the circle as r = 4.4 cm, we get as
since the sides opposite to the equal angles are always equal we get as,
x-2 = 2x-10
===> -2 +10 = 2x-x
==> 8 = x
hence the measurement of the Tangents is,
putting x = 8
2(8)-10 ==> 16-10 ==> 6 cm
length of each tangent is 6 cm.
Answer:
8
Step-by-step explanation:
2x - 10 = x - 2
2x - x = - 2 + 10
x = 8

Can I get help finding the value of m and n
9514 1404 393
Answer:
m = 35
n = 110
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary.
n° = 180° -70°
n = 110
Opposite angles in a parallelogram are congruent.
2m° = 70°
m = 35 . . . . . . divide by 2°

Answer:
Step-by-step explanation:
To complete the given table we will substitute the output value to calculate the input value.
Given function is,
y = 2x + 4
For output value, y = 18
18 = 2x + 4
2x = 18 - 4
x = 7
For output value, y = 22
22 = 2x + 4
2x = 22 - 4
x = 9
For output value, y = 34
34 = 2x + 4
2x = 34 - 4
2x = 30
x = 15
Therefore, table will be,
Input (x) y = 2x + 4 output
7 18
9 22

Answer:
(x+3), (y+9)
Step-by-step explanation:
Adding to x with translate the figure right (subtracting will translate it left), and adding to y will translate it up (subtracting will translate it down).
To get from a point on [tex]y[/tex] to the corresponding point on [tex]y_{1}[/tex], you would move 3 to the right and 9 up, so it would be (x+3), (y+9)

You may realize that we have not yet discussed the distance around a very important geometric shape: a circle! The distance around a circle has a special name called the circumference. To find the circumference of a circle, we use this formula: C = 2πr
In this formula, π is pronounced “pi,” and is defined as the circumference of a circle divided by its diameter:
π
=
C
d
. We usually replace π with the approximation 3.14. The letter r represents the radius of the circle.
Let’s see where the formula for circumference comes from. Figure 4 shows a generic circle with radius r.

Step-by-step explanation:
An expression is a sort of equation but without any number after the equal to sign
so 2x-7 would be an expression but 3x would not be a expression
3x is just a term
2+7 would also not be an expression because this can be simplified into 9 which is not a expression
2x-7=14 is not a expression cuz it has the equal to sign
-14 is not a expression because its a single number
