Answer:
roots are at -14 and -6
Step-by-step explanation:
(x+10)² - 16 = 0
x² + 20x + 100 - 16 = 0
x² + 20x + 84 = 0
(x + 14)(x + 6) = 0
x = -14
x = -6

The functions f(x) and g(x) are defined below. Which expression is equal to f(x) + g(x)?
Answer:
2(x-10)/(x+10)(x-4)
Step-by-step explanation:
Find the complete question attached as a diagram
Given the following
F(x) = x-16/x²+6x-40
Factoring the denominator
F(x) = x-16/x²-4x+10x-40.
F(x) = x-16/x(x-4)+10(x-4)
F(x) = x-16/(x+10)(x-4)
g(x) = 1/x+10
Adding both functions
F(x)+g(x) = x-16/(x+10)(x-4) + 1/x+10.
F(x)+g(x) = x-16+(x-4)/(x+10)(x-4)
F(x)+g(x) = x-16+x-4/(x+10)(x-4)
F(x)+g(x) = x+x-16-4/(x+10)(x-4)
F(x)+g(x) = 2x-20/(x+10)(x-4)
F(x)+g(x) = 2(x-10)/(x+10)(x-4)

Answer:
The radius of these cylinders is approximately 1 foot.
Step-by-step explanation:
According to this graph, the volume of the cylinder is directly proportional to its height, that is, radius remains constant. The expression of direct proportionality:
[tex]V \propto h[/tex]
[tex]V = k\cdot h[/tex] (1)
Where:
[tex]V[/tex] - Volume of the cylinder, in cubic feet.
[tex]h[/tex] - Height of the cylinder, in feet.
[tex]k[/tex] - Proportionality constant, in square feet.
Besides, the proportionality constant is described by this expression:
[tex]k = \pi \cdot R^{2}[/tex] (2)
Where [tex]R[/tex] is the radius of the cylinder, in feet.
If we know that [tex]h = 9\,ft[/tex] and [tex]V = 28.26\,ft^{2}[/tex], then the radius of the cylinder is:
[tex]k = \frac{V}{h}[/tex]
[tex]k = 3.14[/tex]
[tex]R = \sqrt{\frac{k}{\pi} }[/tex]
[tex]R \approx 1\,ft[/tex]
The radius of these cylinders is approximately 1 foot.

Please help me find x and y value?
Answer:
x = 24
y = 19
Step-by-step explanation:
From the picture attached,
m(∠CAB) = (5y - 23)° [Vertically opposite angles]
By applying triangle sum theorem in ΔABC,
(5y - 23)° + (2x + 13)° + 47° = 180°
2x + 5y = 143 -----(1)
(3x)° = (5y - 23)° [Corresponding angles]
3x - 5y = -23 -----(2)
By adding equation (1) and (2)
(2x + 5y) + (3x - 5y) = 143 - 23
5x = 120
x = 24
From equation (2)
3(24) - 5y = -23
72 - 5y = -23
5y = 95
y = 19

Help me with this please
Answer:
1) <2 ; 60
2) <3 ; 60
3) <4 and <3. <4 = 120 and <3 = 60
4) <1, <3, and <4 = 125. <2 = 55
Step-by-step explanation:
1)
Corresponding angles are equal
2)
Alternate interior angles are equal
3)
<4 and <3 are same-side interior angles. This makes them supplementary angles
<4 = 120
<3 = 60
4)
<1 = <4 = <3. All of these angles equal 125.
<2 + <1 = 180
<2 + 125 = 180
<2 = 55
Please help it's for trig
Answer:
-4
Step-by-step explanation:
Given the expression
h(x) = -x^2 +4x
h(-2) = (-2)^2 + 4(-2)
h(-2) = 4 + (-8)
h(-2) = 4 - 8
h(2) = -4
Hence the value of the function when x = -2 is -4
I have been stuck on this question for a while(NO SPAMMING IT IS ANNOYING)The formula used to find the area of a circle is πr² (π=pi). What is the area of a circle with a diameter of 16cm? Use pi = 3.14
Answer:
200.96
or
201 (if you round it up)
Step-by-step explanation:
1) Well, if we know that the diameter (D) is 16 cm, then we know that the radius (r) is 8 cm (D = 2 * r).
2) Next, we square (^2) the radius, and we get 64 (r^2 = r * r = 8*8 = 64)
3) Finally, we multiply π by 64, and we get 200.96 cm^2 (3.14 * 64) which is very close to 201 cm^2.

Choose ONE of the following questions to answer in the box below:
1) Why is point (100, 2) on the graph?
2) What is the x-intercept of the graph? Explain how you know.
3) When will the graph meet the line y = 5 ? Explain how you know.
Answer:
See below
Step-by-step explanation:
Given function:
y = log₁₀ (x)Questions1) Why is point (100, 2) on the graph?
Because:
log₁₀ (100) = log₁₀ (10²) = 2 log₁₀ (10) = 22) What is the x-intercept of the graph? Explain how you know.
The x-intercept is the value of x when y = 0:
log₁₀ (x) = 0x = 10⁰x = 1The x-intercept is (1, 0)
3) When will the graph meet the line y = 5 ? Explain how you know.
log₁₀ (x) = 5x = 10⁵x = 100000When x = 100000

Mr. Pete just got a great deal at Lowe’s on tiles for his new patio. He wants to
tile his patio in the shape that is rectangular. His patio measures 108 inches by
144 inches. Find the fewest square tiles he can use without cutting any of them.
Answer:
The fewest square tiles he can use without cutting any of them = 12 square tiles
Step-by-step explanation:
The given dimensions of Mr. Pete's rectangular patio = 108 inches by 144 inches
The area of the patio = 108 in. × 144 in. = 15,552 in.²
We note that when square tiles are used the must fit both the length and the with of the rectangular patio
Therefore, we have;
The dimensions of the square tiles that the fewest number of tiles is the highest common factor, HCF, of 108 inches and 144
The HCF of 108 and 144 are found from by the prime factors as follows;
108 = 2² × 3³ = 2² × 3² × 3
144 = 2⁴ × 3² = 2² × 3² × 4
From which we have;
The HCF of 108 and 144 = 2² × 3² = 36
Therefore, the size of the sides of the square tiles that will give the fewest number of tiles is 36 inches
The number of the 36 inches square tiles that fit into the length of the rectangular patio = 144 inches/(36 inches/tile) = 4 tiles
The number of the 36 inches square tiles that fit into the breadth of the rectangular patio = 108 inches/(36 inches/tile) = 3 tiles
The total number of tiles he will use = (4 × 3) tiles = 12 tiles = The fewest square tiles he can use without cutting any of them.
