Step-by-step explanation:
Hello,
the line passes through (-8,11) means than y = 11 for x = -8
I believe that you wanted to write the first one as below
[tex]y=-\dfrac{5}{8}x+6[/tex]
in that case for x = -8
y = - 5 * - 1 + 6 = 5 + 6 = 11
hope this helps
The solution is, : y = -5/8x +6, the equation represents the line that passes through (-8,11) and (4,7/2).
What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
here, we have,
First we need to find the slope
m = (y2-y1)/ (x2-x1)
= (7/2 -11)/(4--8)
= (7/2 - 22/2)/(4+8)
= (-15/2)/(12)
= -15/24
Divide top and bottom by 3
-5/8
Then we can use point slope form to write the equation
y-y1 = m (x-x1)
y- 11 =-5/8(x--8)
y- 11 =-5/8(x+8)
Distribute
y-11 =-5/8 x -5
Add 11 to each side
y-11 = -5/8x -5+11
y = -5/8x +6
Hence, The solution is, : y = -5/8x +6, the equation represents the line that passes through (-8,11) and (4,7/2).

Answer:
C. The hypotenuse is [tex]\sqrt{2}[/tex] times as long as either leg.
Step-by-step explanation:
The hypotenuse is square root 2 times as long as the sides is a true statement.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We have to find the true statement about an isosceles right triangle.
Let us use pythagoras theorem to find this
h²=a²+b²
In this case since its an isosceles right triangle, a and b most be the same.
Let's say that the measure of the sides that are equal is x and the hypotenuse is h.
Pythagoras tells us the following:
h²=x²+x²
h²=2x²
Take square root on both sides
h=√2x
Hence, the hypotenuse is square root 2 times as long as the sides

You have $1000 to invest in an account and need to have $2000 in one year. What interest rate would you need to have in order to have this if the amount is compounded weekly? Round your answer to the nearest percent.
Answer:
[tex]\large \boxed{\sf \ \ 70\% \ \ }[/tex]
Step-by-step explanation:
Hello,
We assume that the year is 52 weeks, and we note r the interest rate we are looking for. The rate is expressed in percent and is annually, meaning that the investment is, after the first week :
[tex]1000\cdot (1+\dfrac{r\%}{52})=1000\cdot (1+\dfrac{r}{5200})[/tex]
For the second week
[tex]1000\cdot (1+\dfrac{r}{5200})^2[/tex]
After 52 weeks
[tex]1000\cdot (1+\dfrac{r}{5200})^{52}[/tex]
and we want to be equal to 2000 so we need to solve:
[tex]1000\cdot (1+\dfrac{r}{5200})^{52}=2000\\\\\text{*** divide by 1000 both sides ***}\\\\(1+\dfrac{r}{5200})^{52}=\dfrac{2000}{1000}=2\\\\\text{*** take the ln **}\\\\52\cdot ln(1+\dfrac{r}{5200})=ln(2)\\\\\text{*** divide by 52 ***}\\\\ln(1+\dfrac{r}{5200})=\dfrac{ln(2)}{52}\\\\\text{*** take the exp ***}\\\\\displaystyle 1+\dfrac{r}{5200}=exp(\dfrac{ln(2)}{52})=2^{(\dfrac{1}{52})}=\sqrt[52]{2}\\\\r = 5200\cdot (\sqrt[52]{2}-1)=69.77875...[/tex]
Rounded to the nearest percent, the solution is 70%.
If you want to double your capital in one year with weekly compounding you need an interest rate of 70% !!

Step-by-step explanation:
Notice how you get the same value each time when you divide the cost by the number of downhill rides
5/2 = 2.5 10/4 = 2.5 15/6 = 2.5Moreover when the downhill rides grow by 2 the total cost grows by 5
so we can state :

How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the rectangle be represented as ABCD
Now , the coordinates of the rectangle are

Given
Solid Shapes: Cone, Cylinder, Sphere
Cost of Cone Clay = $12
Cost of Cylinder Clay = $30
Cost of Sphere Clay = $28
Required
Determine the volume of each shape
Which is the best buy
CONECalculating VolumeThe volume of a cone is calculated as thus;
[tex]Volume = \frac{1}{3}\pi r^2h[/tex]
From the attached diagram
Radius, r = 9 inches; Height, h = 12 inches and [tex]\pi = 3.14[/tex]
Substitute these values in the above formula;
[tex]Volume = \frac{1}{3} * 3.14 * 9^2 * 12[/tex]
[tex]Volume = \frac{3052.08}{3}[/tex]
[tex]Volume = 1017.36\ in^3[/tex]
Calculating Volume:Price RatioThe unit cost of the cone is calculated as thus;
[tex]Volume:Price = \frac{Volume}{Total\ Cost}[/tex]
Where
[tex]Volume = 1017.36\ in^3[/tex]
[tex]Total\ Cost = \$12[/tex] (Given)
[tex]Volume:Price = \frac{1017.36\ in^3}{\$ 12}[/tex]
[tex]Volume:Price = 84.78 in^3/\$[/tex]
[tex]Volume:Price = 84.78 in^3:\$1[/tex]
CYLINDERCalculating VolumeThe volume of a cylinder is calculated as thus;
[tex]Volume = \pi r^2h[/tex]
From the attached diagram
Radius, r = 9 inches; Height, h = 12 inches and [tex]\pi = 3.14[/tex]
Substitute these values in the above formula;
[tex]Volume = 3.14 * 9^2 * 12[/tex]
[tex]Volume = 3052.08\ in^3[/tex]
Calculating Volume:Price RatioThe unit cost of the cone is calculated as thus;
[tex]Volume:Price = \frac{Volume}{Total\ Cost}[/tex]
Where
[tex]Volume = 3052.08\ in^3[/tex]
[tex]Total\ Cost = \$30[/tex] (Given)
[tex]Volume:Price = \frac{3052.08\ in^3}{\$ 30}[/tex]
[tex]Volume:Price = 101.736\ in^3/\$[/tex]
[tex]Volume:Price = 101.736\ in^3:\$1[/tex]
SPHERECalculating VolumeThe volume of a sphereis calculated as thus;
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
From the attached diagram
Radius, r = 9 inches; and [tex]\pi = 3.14[/tex]
Substitute these values in the above formula;
[tex]Volume = \frac{4}{3} * 3.14 * 9^3[/tex]
[tex]Volume = \frac{9156.24}{3}[/tex]
[tex]Volume = 3052.08\ in^3[/tex]
Calculating Volume-Price ratioThe unit cost of the cone is calculated as thus;
[tex]Volume:Price = \frac{Volume}{Total\ Cost}[/tex]
Where
[tex]Volume = 3052.08\ in^3[/tex]

Divide the largest one by the smallest one : for example, the number 4 is 42=2× larger than the number 2.
Indeed, If you multiply 2 by 42 you'll get 4.
Of course, if a number is n× larger than another, then this other is n× smaller than the first one.
It will of course work with floating point : 0.6×10.6≈0.6×1.6667=1 so 1 is ~1.6667 times larger than 0.6 while 0.6 is ~1.6667 smaller than 1.

2/5(10)+3(6)-6
First, multiply 2/5 and 10
4+ 3(6)-6
Next, multiply 3 and 6
4+18-6
Next, add 4 and 18
22-6
Finally, subtract 6 from 22

To find the equation, we need to find the slope and the y-intercept. Afterwards, we can put the numbers into the slope-intercept form:
[tex]y=mx+b[/tex]
From the graph, we can see that the line crosses the y-intercept at y=-6. Thus, the y-intercept (b) is -6.
Now we need to find the slope. Pick any two points where the line crosses. I'm going to pick (0,-6) and (4,-7).
[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{-7-(-6)}{4-0}= -1/4[/tex]

Step-by-step explanation:
Given the ratio of the radii of 2 similar spheres = a : b , then

ratio of volumes = 5³ : 9³ = 125 : 729
For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What is the resulting equation? 1. 3x + 5x - 4 = 1 2. 3x + 4 - 5x = 1 3. 3x + 5x + 4 = 1
Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:
[tex]3x+y=1\\y+4=5x[/tex]
To make a substitution of the second equation into the first equation, we need to isolate the y variable in the second equation. Thus:
[tex]y+4=5x\\y=5x-4[/tex]
Now, we can substitute this into the first equation. Therefore:
[tex]3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1[/tex]
