Answer:
A) x^2 + 2x+ y^2 - 4y + z^2 - 2z - 63 = 0
B) radius = 5
center = (4,-1,-3)
Step-by-step explanation:
[tex]x^2 + y^2 + z^2 - 8x + 2y + 6z + 1 = 0[/tex]
A ) Determine the curve in which the sphere intersects the yz-plane
determine the radius ( r ) = √((6-(-1))2+(-2-2)2+(3-1)2) = √69
next the equation of the sphere ( curve in which the sphere intersects the yz-plane )
x^2+2x+y^2-4y+z^2-2z-63 = 0
B) determine the center and radius of the sphere
X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0
(x-4)2+(y+1)2+(z+3)2 = 25 = 52
radius = 5
center = (4,-1,-3)
Two angles of a triangle have the same measure and the third one is 30 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.
Answer:
75 degrees
Step-by-step explanation:
Isosceles triangle with 3rd angle being 30 degrees:
2x + 30 = 180
2x = 150
X = 75
Paul, Colin and Brian are waiters.
One night the restaurant earns tips totalling £78.40.
They share the tips in the ratio 2:1:5.
How much more does Brian get over Colin?
Let 2x = Paul
Let x = Colin
Let 5x = Brian
2x + x + 5x = 78.40
8x = 78.40
x = 78.40 ÷ 8
x = 9.8
Brian gets 5(9.8) which is 49.
Colin gets 9.8.
Brain over Colin means 49/9.8 = 5.
Brain gets £5 more than Colin in terms of a tip.
Identify the method that will be used in solving for X

which value of p is the solution of 5p-1=2p+20
Answer:
p=7
Step-by-step explanation:
5p-1=2p+20 first add 1 to both sides to get 5p=2p+21, then subtract 2p from both sides to get 3p=21, then divide by three to get p=7
The ratio of the side lengths of a triangle is 2:3:4. The shortest side is 15 inches. What is the perimeter? Explain. Pleas show your work. I will give brainiest to the best and first answer
Ratio of the sides of the triangles,
2 : 3 : 4
Let's consider each side to be
2x,3x and 4x
Therefore the perimeter of the triangle is,
2x + 3x + 4 x = 9x
The shortest side is 15 inches.
We know that the smallest value in the above ratio is 2
Therefore,
2x = 15 inches
x = 7.5 inches
☞Perimeter of the triangle
= 9x
= 9 * 7.5 inches
= 67.5 inches

A cylindrical garbage can has the dimensions shown.
A cylinder has a diameter labeled twelve inches and height labeled fifteen inches.
What is the area of the horizontal cross section of the cylinder? Use 3.14 for π.
Answer:
113.04 square inchesStep-by-step explanation:
Horizontal cross-section of a cylinder is a circle with same dimension as its base
Given diameter
12 inchesArea formula
A = πr² = πd²/4So the area of cross section is:
A = 3.14*12²/4 = 113.04 square inchesUse a system of linear equations to find the quadratic function
f(x) = ax2 + bx + c
that satisfies the given conditions. Solve the system using matrices.
f(−2) = −5, f(1) = −8, f(2) = −25
Answer:

Since the 1800s, fossil fuels have been used to meet the energy needs of many human activities.
Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.
Group of answer choices
There is more available space for carbon to become fossil fuels.
There is less carbon in storage.
There will be less carbon in the water.
There is more carbon in the atmosphere.
There will be more carbon respired by organisms.
There will be less carbon released through decomposition.
Answer:
Below.
Step-by-step explanation:
There will be more carbon in the atmosphere.
There is less carbon in storage.
Answer:
1. There is more carbon in the atmosphere.
2. There is more available space for carbon to become fossil fuels.
Step-by-step explanation:
When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.
