Answer:
altitude = 30 cm
lateral surface area = 301 cm² (approximately)
Step-by-step explanation:
let the altitude be x,
240=6*4*x/3
or, x=30 cm
Lateral surface area,
=l×√(w/2)²+h²]+w×√[(l/2)²+h²]
=6×√[(4/2)²+30²]+4×√[(6/2)²+30²]
≈300.99806
≈ 301 cm²

the table below represents a linear function f(x) and the equation represents a function g (x)
part a: write a sentence to compare thw slope of thw two functions and show thw steps you used to determine the slope of f(x) and g(x).
part b: which function has a greater y-intercwpt? justify your answer
Answer:
Step-by-step explanation:
a). For function 'f',
Slope of a linear function 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]
For the function 'f' given in the table,
Slope of the linear function passing through two points (-1, -5) and (0, -1) given in the table,
Slope = [tex]\frac{-5+1}{-1-0}[/tex]
= 4
Equation of the line passing through a point (0, -1) and slope = 4 will be,
y - y' = m(x - x')
y + 1 = 4(x - 0)
y = 4x - 1
f(x) = 4x - 1
For function 'g',
Equation of the function 'g' has been given as,
g(x) = 4x + 3
By comparing this equation with the slope-intercept equation of a line,
y = mx + b
Therefore, slope of the function 'g' is,
m = 4
Since slopes of both the functions are same, linear graphs of both the functions will be parallel.
b). Equation of the function 'f' is,
f(x) = 4x - 1
y-intercept of the function = -1
Equation of function 'g',
g(x) = 4x + 3
y-intercept = 3
Therefore, function 'g' will have the greater y-intercept.

A rectangle has dimensions of 7 in. by 5 in. Consider the solid of revolution formed when the rectangle is rotated about its 7 in. side. What is the solid formed by the revolution?
cone cylinder What is the radius (in inches) of the base of the solid of revolution?
in What is the height (in inches) of the solid of revolution?
in Find the exact volume (in cubic inches) of the solid of revolution.
Answer:
(a) Cylinder, R = 5 in, H = 7 in
(b) Volume = 549.5 cubic inches
Step-by-step explanation:
length, L= 7 in
width, W = 5 in
(a) The solid is cylinder.
Radius, R = 5 in
(b) Height = 7 in
Volume of the cylinder
[tex]V = \pi r^2 h\\\\V = 3.14 \times 5 \times 5\times 7\\\\V = 549.5 in^3[/tex]

Answer:
[tex]\boxed {\boxed {\sf 14 \sqrt{5}}}[/tex]
Step-by-step explanation:
We are asked to combine the radicals. We have the following expression:
[tex]8 \sqrt{5} + 2 \sqrt{45}[/tex]
Currently, we cannot combine these radicals. The value under the square root is not the same for both terms.
However, we can simplify the radical 2 √45 because the value under the radical is divisible by a perfect square.
45 can be divided by 9 (the perfect square) for a quotient of 5. So, we can simplify the radical using this information.
Break the radical into 2 radicals: 9 and 5.
[tex]8 \sqrt{5}+ 2 \sqrt{9}\sqrt{5}[/tex]
Notice that a perfect square is under the radical. √9 can be simplifed to 3.
[tex]8 \sqrt{5}+ 2 *3 \sqrt{5}[/tex]
Multiply 2 and 3.
[tex]8 \sqrt{3} + 6 \sqrt{5}[/tex]
Now the value under the radical is the same for both terms, and we can add the numbers in front of the radicals.
[tex]14 \sqrt{5}[/tex]
The radicals combined is equal to 14√5
Find a degree 3 polynomial with real coefficients having zeros 1
and 2−2i and a lead coefficient of 1. Write P in expanded form. Be sure to write the full equation, including P(x)=
9514 1404 393
Answer:
P(x) = x³ -5x² +12x -8
Step-by-step explanation:
If the coefficients are real, then the complex roots must be conjugates. The third root is 2+2i. For root r, (x -r) is a factor, so the factorization is ...
P(x) = (x -1)(x -2 +2i)(x -2 -2i) = (x -1)((x -2)² +4) = (x -1)(x^2 -4x +8)
Expanding further, we find ...
P(x) = x³ -5x² +12x -8

Solve the quadratic equation 12x^2 - 288 = 0 using the square root method.
Answer:
C) x = ± 4
Step-by-step explanation:
12x² - 288 = 0
Add 288 on both sides. Anything plus zero gives itself.12x ² = 288
Divide both side by 12[tex] \small \sf \: x {}^{2} = \frac{288}{12} \\ [/tex]
Divide 288 by 12 to get 24[tex]\small \sf x {}^{2} = \frac{ \cancel{288 }}{ \cancel{12}} \\ [/tex]
x² = 24
Taking square root of each side and remember to use positive and negative roots[tex] \small \sf \: \sqrt{x {}^{2} } = ± \sqrt{ 24} [/tex]
[tex] \small \sf \: x_1, _2 = ± \sqrt{ 24} [/tex]
[tex] \small \sf \: x_1, _2 = ± 4.899 [/tex]
Find the missing length (picture below)
Answer:
Step-by-step explanation:
because these are similar triangles, that is, one is a bigger of smaller version of the other, then we know, that the bigger triangle is just 2 times bigger than the smaller, or 2x of any side of the small one
sooo 2(20) =40
so we know that side n of the bigger triangle is 40
A line contains the points (3,1) and (-6,4) what is the equation for this line in slope intercept form
Answer:
y = (-1/3)x + 2
Step-by-step explanation:
Since points (3,1) and (-6,4) lie on y = (-1/3)x + c , it should satisfy the this equation. Thus, intercept is 2.
