Step-by-step explanation:
The solutions to a quadratic equation give the x- intercepts of the graph
The x-values stand for the x-intercepts as it relates to plotting the graph of the equation
How to determine the true statement?On a graph of a quadratic function:
When the graph of the function crosses the x-axis, then the graph has real rootsWhen the graph of the function does not cross the x-axis, then the graph has complex rootsIn scenario (a), the points where the graph crosses the x-axis are the x values of the function or the x-intercepts
Hence, the true option is (a) x-intercepts

The figure shows the dimensions of a birdhouse Sharri built. How much birdseed will it take to fill Sharri’s birdhouse completely? A. 12,000 B. 3600 C. 3000 D. 600
The given figure consists of rectangular and triangular prisms. The birdseed that it will take to fill Sharri’s birdhouse completely is 5100
How to calculate the volume of a figure?The given figure consists of rectangular and triangular prisms. The volume of the prism is expressed as:
Volume of the rectangular prism = lwh
Vr =10 * 15 *30
Vr = 4500 square cm
For the triangular prism
Vt = BH
B = 0.5 * 4 * 15
B = 30 square units
H = 20cm
Vt =20 * 30
Vt = 600 square units
Total volume = 4500 + 600 = 5100
Hence the birdseed that it will take to fill Sharri’s birdhouse completely is 5100

Answer:
4.71 m
Step-by-step explanation:
Using cosine rule,
[tex]x {}^{2} = 2 {}^{2} { + 3 {}^{} }^{2} - 2(2)(3) \cos(140) \\ x = \sqrt{13 - 12 \cos(140) } \\ x = 4.71m[/tex]
Answer:
Well there if you look at the choices given its only 4.71 and 8.52. According to the model is looks like we need to find the hypotnuse which is the longest lightning of any triangle. But here’s the thing, in every triangle if you add the two legs, the sum of that number has to be GREATER then the hypotnuse or it wouldn’t stick. If your dd 2+3 together you get 5. Only the last option is greater then 5. The final answer is 8.52.
Remeber, you CAN’T use the Pythagorean theroum on any triangle with out a 90 degree angle. Pythagorean Theorem only works for right triangles. This is why the first option is given to trick you.

What would be the volume of a sphere if the radius is 6 in? Round to nearest tenth if needed
Answer:
904.8cm
Step-by-step explanation:
The volume of a sphere is given as
[tex] \frac{4}{3}\pi {r}^{2} [/tex]
There is only one variable, the radius, which we are given in the problem.
since the radius is 6 cm, we can plug that in to the formula
[tex] \frac{4}{3} \pi {6}^{2} [/tex]
Put this into the calculator, and we see that the volume is 904.8cm rounded to the nearest tenth.

It takes a bear 9 more days to eat a barrel of honey alone than it takes the bear and a second bear to eat the barrel of honey together. It takes the first bear 7 fewer days to eat a barrel of honey alone than it takes the second bear to eat a barrel of honey alone. In how many days can the two bears eat a barrel of honey together?
No links please.
Answer:
it takes the bears 12 days to eat honey together.
Step-by-step explanation:
1/x+9+1/x+16=1/x
(solve this using cross multiplication)
= x^2 = 144
x=12
answer: 12
explanation:
let x=two bears eating honey together
let x+9=first bear
let (x+9)+7=second bear **because we know the second day takes 7 more days to eat the same amount of honey as the first bear**
since the bears can finish a barrel of honey over multiple days, they can only finish part of the barrel of honey in one day.
therefore...
x/(x+9)+x(x+16)=1 or x*1/(x+9)+x*1/(x+16)=1 **the equation equals 1 because you are trying to find how much honey they eat in one day aka 1=single day**
if you solve, you get x=-12; x=12. it can only be the positive value so x=12 is your answer. your welcome fellow rsm students.

Select ALL choices that are zeros of this function y=x2 +12x +32
Answer:
{-8, -4}
Step-by-step explanation:
Rewrite this function y=x2 +12x +32 as y = x^2 + 12x + 32; " ^ " indicates exponentiation.
Set this x^2 + 12x + 32 equal to zero (to find the zeros):
x^2 + 12x + 32 = 0. Let's solve this using the quadratic formula, which applies when ax^2 + bx + c = 0:
-b ± √(b^2 - 4·a·c)
x = -------------------------------
2a
The coefficients of the given quadratic are {1, 12, 32}. Thus, the discriminant is
b^2 - 4ac, or 12^2 - 4(1)(32), or 144 - 128, or 16. Therefore, we have:
-12 ± √16 -12 ± 4
x = -------------------- which simplifies to: x = --------------- = { -8, -4}
2 2
The zeros are {-8, -4}

the common factor of 6x 66xy
Answer:
6x and 1x or x
Step-by-step explanation:
the highest common factor of 6x and 66xy in 6x
6x ÷ 6x = 1
66xy ÷ 6x = 11y
the lowest common factor of 6x and 66xy is 1x or x
6x÷ 1x =6
66xy÷ 1x = 66y
6x÷ x = 6
66xy ÷ x = 66y
NOTE
1x and x is the same

Step-by-step explanation:
12x6=72m2

72-8=64m2
The area for the given dimensions of Jared's classroom is, 64 m²
What is the area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Given that,
The dimensions of Jared's classroom are,
12 m, 4 m, 6 m, 4 m, 2 m, 8 m
we can divide the area of classroom in two parts,
first A₁, having side lengths of 6 m & 8 m
second A₂, having side lengths of 4 m & 4 m
Jared's classroom area = A₁ + A₂
A₁ = 6 × 8
= 48
A₂ = 4 × 4
= 16
A = A₁ + A₂
= 16 + 48
= 64
The area of classroom is 64 m²
