Find a value of k such that kx2 + 12x − 4 = 0 has one real-number solution. Explain.
Answer: if x is to the 2 power then
kx^2+12x-4=0 Add 4 to the both sides
kx^2+12x=4 Divide both sides by 12
kx^2=1/3x square root the both sides
k=0.6x

unchack Hide excused activities
Answer:
Linear, the linear term is -21x and the constant term is -20. Last option is the answer
Step-by-step explanation:
We are given the following function:
[tex]y = (x - 5)(5x + 4) - 5x^2[/tex]
First we have to simplify y, before solving the question:
[tex]y = (x - 5)(5x + 4) - 5x[/tex]
Applying the distributive property:
[tex]y = 5x^2 + 4x - 25x - 20 - 5x^2[/tex]
[tex]y = 0x^2 - 21x - 20[/tex]
[tex]y = -21x - 20[/tex]
No quadratic term, so it is linear.
The linear term is -21x and the constant term is -20.
-12.3 + 7v = 10.1 solve for V
Answer:
v=3.2
Step-by-step explanation:
Let's solve your equation step-by-step.
−12.3+7v=10.1
Step 1: Simplify both sides of the equation.
7v−12.3=10.1
Step 2: Add 12.3 to both sides.
7v−12.3+12.3=10.1+12.3
7v=22.4
Step 3: Divide both sides by 7.
7v /7 = 22.4 /7
v=3.2

Seismologists use the Richter scale to express the energy, or magnitude, of an earthquake. The Richter magnitude of an earthquake, M, is related
energy released in ergs E shown by the formula
M
flog (10)
A recent earthquake in Peru registered a 4.0 on the Richter scale. How much energy in ergs was released by this earthquake?
(Enter you answer in terms of 10 and use Shift 6^ for exponents)
ergs
Answer:
10¹⁸ ergs
Step-by-step explanation:
From the question,
Using the expression
M = [tex]\frac{4}{5}[/tex]log(E/10¹³)................. Equation 1
Where M = Richter magnitude of earth quake, E = Energy released in ergs.
Given: M = 4.0
Substitute into equation 1 amd solve for E
4 = [tex]\frac{4}{5}[/tex]log(E/10¹³)
Log(E/10¹³) = (4×5)/4
Log(E/10¹³) = 5
E/10¹³ = 10⁵
E = 10⁵×10¹³
E = 10⁵⁺¹³
E = 10¹⁸ ergs

Answer:
a10 = 15
an = 6n - 45
Step-by-step explanation:
a12 = 27 = a + 11d - eq 1
a14 = 39 = a + 13d - eq 2
eq 2 - eq 1
2d = 12
d = 6
a + 11(6) = 27
a + 66 = 27
a = -39
a10 = a + 9d = -39 + 9(6) = 15
Tn = a + (n-1)d
-39 + 6(n - 1)
-39 + 6n -6
an = 6n - 45

Answer:
y = x
Step-by-step explanation:
Hi,
We know that in the equation...
y = mx + b
m = slope
So, to find the equation of the line, we have to plug in what we already know. So...
-7 = 1 (-7) + b
Solve...
-7 = -7 + b
b = 0
That means that your equation is...
y = x
(you don't have to put the one in front of the x)

At his birthday party, Aiden collected 15% of the candy that fell out of the piñata. If Aiden collected 6 pieces of candy, how many pieces of candy fell out of the piñata?
Answer:
40 pieces
Step-by-step explanation:
To make it easier, I'm gonna divide 15 by 3 and then multiply it by 2. Same with 6.
10% of candy = 4 pieces.
Multiply by 10
100% of candy = 40 pieces.
Find the area of a square with apothem of 10m.
Answer:
[tex]Area = 400m^2[/tex]
Step-by-step explanation:
Given
[tex]a = 10m[/tex] --- apothem
Required
The area of the square
The relationship between the apothem (a) and the length (L) of 1 side of a square is:
[tex]a = \frac{L}{2}[/tex]
Make L the subject
[tex]L = 2a[/tex]
Substitute [tex]a = 10m[/tex]
[tex]L = 2*10m[/tex]
[tex]L = 20m[/tex]
The area is then calculated as:
[tex]Area = L^2[/tex]
So:
[tex]Area = (20m)^2[/tex]
[tex]Area = 400m^2[/tex]

what is angle 1 im marking brailiest
Answer:
86
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
1. The other angle marked with one arc must also be 43 deg.
2. The two angles put together make an angle of 86 deg.
3. In a parallelogram, the angle at lower right and the angle at upper right are supplementary (they add up to 180 deg.). The upper right angle is 180 - 86 = 94 deg.
4. The angle at lower left is the same, 94 deg.
5. The angles marked with two arcs are half of 94 deg. = 47 deg.
6. Now you have two out of three angles in the triangle. All three angles add up to 180 deg. so the measure of angle 1 is 180 - 47 - 43 = 90 degrees.
The area of each triangular face is 30 square feet true or false
