What is an equation of the line that passes through the points (1,6) and (2, 7)?
The equation of the line that passes through the points (1,6) and (2,7) is y = x + 5.
We can use the point-slope version of the equation, which is: to determine the equation of a line passing through two specified points.
y - y₁ = m(x - x₁)
where (x₁, y₁) are the coordinates of one of the points, m is the slope of the line, and (x, y) are the coordinates of any other point on the line.
Use the points (1,6) and (2,7) to find the equation of the line:
Using (x₁, y₁) = (1,6):
y - 6 = m(x - 1)
Now, substitute the coordinates (2,7) into the equation:
7 - 6 = m(2 - 1)
1 = m
So, the slope of the line is m = 1.
Substitute this value into the equation:
y - 6 = 1(x - 1)
y - 6 = x - 1
y = x + 5
Therefore, the equation of the line that passes through the points (1,6) and (2,7) is y = x + 5.

The model has a circular base with a diameter of 48 centimeters and a height of 12 centimeters. Find the volume of foam in the model to the nearest tenth. Use 3.14 for π.
3. The volume of the Pringle Chips container is approximately 2034.72 cubic inches.
4. The cake takes up approximately 7317 cubic inches of space.
5. The volume of foam in the model of the volcano is approximately 7234.08 cubic centimeters.
1. The units for Volume are always cubed.
2. Volume is the amount of space an object takes up. True.
3. To calculate the volume of the Pringle Chips container, we need to find the volume of a cylinder. The formula for the volume of a cylinder is V = πr^2h, where π is a constant (approximately 3.14), r is the radius, and h is the height. Given that the diameter is 9 inches, the radius would be half of that, which is 4.5 inches. Substituting the values into the formula, we have:
V = 3.14 * (4.5)^2 * 32
V = 3.14 * 20.25 * 32
V ≈ 2034.72 cubic inches
4. To find the volume of the 3-tier cake, we need to find the volume of each tier separately and then add them together. Since all the tiers are cylinders, we can use the formula V = πr^2h.
Tier 1:
V1 = 3.14 * (12)^2 * 10 = 4521.6 cubic inches
Tier 2:
V2 = 3.14 * (8)^2 * 10 = 2010.4 cubic inches
Tier 3:
V3 = 3.14 * (5)^2 * 10 = 785 cubic inches
Total volume:
Total V = V1 + V2 + V3
Total V = 4521.6 + 2010.4 + 785
Total V ≈ 7317 cubic inches
5. To find the volume of the Styrofoam model of the volcano, we can use the formula for the volume of a cone, V = (1/3)πr^2h. Given that the diameter is 48 centimeters, the radius would be half of that, which is 24 centimeters. Substituting the values into the formula, we have:
V = (1/3) * 3.14 * (24)^2 * 12
V = (1/3) * 3.14 * 576 * 12
V ≈ 7234.08 cubic centimeters

For the polynomial below, -3 and -1 are zeros.
g(x)=x² +6x³
+9x²-2x-6
Express g (x) as a product of linear factors.
The complete factorization of the polynomial is:
h(x) = (x - 3)*(x - 1)*(x + 2)
Here we have the polynomial:
g(x)= x³ - 2x² - 5x + 6
And we know that x = 3 is a zero, then (x - 3) is a factor.
So if f(x) = a*x² + b*x + c
We can write:
h(x) = (x - 3)*f(x)
Let's find f(x).
Expanding that:
x³ - 2x² - 5x + 6 = (x - 3)*(a*x² + b*x + c)
x³ - 2x² - 5x + 6 = ax³ + bx² + cx - 3ax² - 3bx - 3c
x³ - 2x² - 5x + 6 = ax³ + (b - 3a)x² + (c - 3b)x - 3c
Comparing like terms, we can see that:
a = 1
b - 3 a = -2
c - 3b = -5
-3c = 6
With the first and last equation we can get:
a = 1
c = 6/-3 = -2
Now with one of these values and the second or third equation we can find the value of b.
b - 3 a = -2
b - 3*1 = -2
b - 3 = -2
b = -2 + 3 = 1
Then:
f(x) = x² + x - 2
The zeros of this quadratic function are given by:
x = -1±3 / 2
so, we get,
x = (-1 + 3)/2 = 1
x = (-1 - 3)/2 = -2
Then we can factorize this as:
f(x) = (x - 1)*(x + 2)
And then we can write h(x) as:
h(x) = (x - 3)*(x - 1)*(x + 2)

Find the volume of the triangular prism to the right.
5 ft
10 ft
The volume of the prism is ? ft^3
Answer:
rectangular is 114ft and triangular is 112ft
Step-by-step explanation:
Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT
Since VR = length * width and height
VR = 6*x*3
VR = 18x ft³
Also VT = Length *width * Height/2
VT = (7 * x * 4)/2
VT = 28x/2
VT = 14xft³
Since VR = 32 + VT
18x = 32+(14x)
collect like terms
18x-14x = 32
4x = 32
divide both sides by 4
4x/4 = 32/4
x = 8
Volume of the rectangular prism = 18x
Volume of the rectangular prism = 18*8
Volume of the rectangular prism = 144ft³
Volume of the right triangular prism = 14x
Volume of the rectangular prism = 14*8
Volume of the rectangular prism = 112ft³
(3x-15)(2x+7) what is x
Answer:
The chosen topic is not meant for use with this type of problem. Try the examples below.
2 = |3x|
−4/5x + 1/25 = 0
3x = 4 − x
Answer
Step-by-step explanation:
This has to be equal to something in order to solve it. I'm going to guess that it is equal to 0
(3x-15)(2x+7) = 0
That means that
3x - 15 = 0
3x = 15
x = 15/3
x = 5
or
2x + 7 = 0
2x = - 7
x = -7/2
x = - 3.5
The only other thing I can think of that this could equal is multiplying the two binomials together.
3x * 2x = 6x^2
3x*7 = 21x
-15*2x = - 30x
-15 * 7 = - 105
6x^2 - 7x - 105
But that does not solve for x.

What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism. A rectangular prism also refers to a cuboid. A cuboid and a rectangular prism have the same cross-section.
First step:-
Right triangular prism=1⁵/₆ inches= 11/6 inches
Height of the base=8²/₃ inches = 26/3 inches
Second step:-
Surface area = 5(10× 10) + (0.5÷ 10 × 26/3) + 3(10× 11/6)
Surface area = 5(100) +43.33+ 3(18.33)

y= 71+ 6x
y= 10+ 10x
What pair of numbers solves the system? Use values accurate to the
nearest tenth.
The pair of numbers that solves the system is (15.25, 164.5).
The system of equations, in slope-intercept form, for Farmer Elentire and Farmer Hopt are:
y = 6x + 71 (for Farmer Elentire)
y = 10x + 10 (for Farmer Hopt)
To find the pair of numbers that solves the system, we need to find the point where the two lines intersect.
We can do this by setting the equations equal to each other:
6x + 71 = 10x + 10
Solving for x, we get:
4x = 61
x = 15.25
Now that we know x = 15.25, we can plug this value into either equation to find y.
71 + 6x = 10 + 10x
Subtracting 6x and 10 from both sides, we get:
61 = 4x
Dividing both sides by 4, we get:
x = 15.25
Now we can use either of the original equations to find y. Let's use the first equation:
y = 71 + 6x = 71 + 6(15.25) ≈ 164.5
Using the first equation, we get:
y = 6(15.25) + 71
y = 163.5
Therefore,
The pair of numbers that solves the system is (15.25, 163.5), accurate to the nearest tenth.

What is the continuity of a function?A function is said to be continuous if there are no breaks or jumps in the functions
Conditions for continuity of a function

We need to determine the interval of continuity, We proceed as follows.
Since f(x) = sin⁻¹x, x ≠ π/4 , we know that the minimum value of x is - 1 and its maximum value is 1.
So, x must lie in the interval (-1, 1) for x ≠ π/4,
Now, when x = π/4 f(x) = sinx. We know that x = π/4 lies in the interval (-1, 1).
But we know that f(x) = sinx at x = π/4. So, there is a removable discontinuity at x = π/4.
So, from the left, f(x) is continuous on the interval [-1, π/4) and from the right, f(x) is continuous on the interval (π/4, 1]
So, combining both intervals, we have f(x) is continous on the interval [-1, π/4) ∪ (π/4, 1] and since f(x) = sinx at x = π/4, there is a removable discontinuity at x = π/4

Find area between two curves
9514 1404 393
Answer:
0.5
Step-by-step explanation:
The "enclosed area" can be taken to mean different things. Here, we consider it to mean the finite area bounded between the two curves, regardless of which curve is higher value than the other.
The area is bounded on the interval [0, 2]. On half that interval y1 > y2; on the other half, y2 > y1. This means the integral of the area between the curves will be different for one part of the interval than for the other. (The curves are symmetric about the point (1, 0).)
The area on the interval [0, 1] is given by the integral ...
\(\displaystyle\int_0^1{(y_1-y_2)}\,dx=\int_0^1{((x-1)^3-(x-1))}\,dx\\\\=\int^1_0{(x(x-1)(x -2))}\,dx=\left.(\frac{x^4}{4}-x^3+x^2)\right|^1_0=\boxed{\frac{1}{4}}\)
The area on the interval [1, 2] is the integral of the opposite integrand, but has the same value.
The positive area over the whole interval from 0 to 2 is 1/4+1/4 = 1/2.
If you simply integrate y2-y1 or y1-y2 over that interval, the result is 0.
