Answer:
Step-by-step explanation:
You should use a ^ to indicate an exponent. x^2 is the same as x².
x² + 9x + 20
Replace the x with (-5).
(-5)² + 9(-5) + 20 = 25-45+20 = 0
Then do the same with x = (-3):
(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2
You can do x = (-6)

On the number line bug A is moving in the positive direction from the point 0, and a bug B is moving in the negative direction from the point 0. The speeds of both bugs are constant. Both leave 0 at the same time, and three seconds later A has reached 18 and B has reached -15
If x is the point reached by A after t seconds, and y is the point reached by B after t seconds, express x and y in terms of t.
Answer:
x =6t
y = - 5t
How would I go about solving this problem? I used the Pythagorean theorem but still got it wrong
Answer:
B. 20
Step-by-step explanation:
Using the Pythagorean Theorem, you have:
[tex]a^2 + b^2 = c^2\\24^2 + 32^2 = c^2\\576 + 1024 = c^2\\1600 = c^2\\c = 40[/tex]
So you know side AB is 40 inches long. It asks the length of the midpoint to point A, so you have to do 40/2 = 20 inches

Solve the equation with the quadratic formula 4k^2-11k-18=0
Answer:
D
Step-by-step explanation:
Quadratic formula tells us that the roots are equal to:
[tex]\frac{-b\pm \:\sqrt{b^2-4ac}}{2a}[/tex]
The letters are just the coefficients, so a = 4, b = -11, and c = -18. Plugging these values into the formula we get:
[tex]\frac{-11\pm \sqrt{11^2-4\cdot \:4\left(-18\right)}}{2\cdot \:4}[/tex]
Which when simplified tells us that the roots are:
[tex]\frac{-11+\sqrt{409}}{8}[/tex] or [tex]\frac{-11-\sqrt{409}}{8}[/tex]
Remember the plus or minus sign is what gives us two answers.

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han caido de 100.000 unidades por mes a 80.000. Si las ventas siguen un patron de decrecimiento exponencial, cuantas unidades habra despues de los siguientes dos meses?
Answer:
51,200 unidades
Step-by-step explanation:
Paso 1
Calculamos el porcentaje de disminución
= 100000 - 80000/100000 × 100
= 20000/100000 × 100
= 20%
Por lo tanto, el porcentaje de disminución cada mes = 20%
Paso 2
La fórmula de la disminución exponencial
y = a (1 - r) ^ t
a = 80.000
r = 20% = 0,2
t = tiempo en meses = 2
y = 80000 (1 - 0,2) ^ 2
y = 51.200 unidades
Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.
Una función exponencial decreciente tiene el siguiente formato:
[tex]A(t) = A(0)(1 - r)^t[/tex]
En que:
A(0) es la cuantia inicial.r es la tasa de desintegración.En este problema:
Inicialmente, 100000 unidades por mes, o sea, [tex]A(0) = 100000[/tex].Cuatro meses después, 80000 unidades por mes, o sea, cuando [tex]t = 4, A(t) = 80000[/tex], e esto es usado para encontrar r.[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]80000 = 100000(1 - r)^4[/tex]
[tex](1 - r)^4 = 0.8[/tex]
[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]
[tex]1 - r = 0.945742[/tex]
Por eso:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 100000(0.945742)^t[/tex]
Apos el siguinte dos meses, hay el mes 6, por eso:
[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]
Habra 71.554 unidades despues de los siguientes dos meses.

On the number line, which point is the closest pi .
A.
B.
C.
D.
The closest point to the number line is C.
Hence Option C is correct.
In the given number line
There are 10 equidistant points between 3.1 and 3.2
So, the set of points shown on the line is,
{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}
Therefore,
Point c represents point 3.14 approximately.
Since we know that π is an irrational number,
So it is non-terminating and non-repeating but for approximation,
π = 22/7
π ≈ 3.142
Hence,
The point C is very close to the π.

6 pipes are required to fill a tank in 80 minutes. If we use 5 such types of pipes, how much time it will take to fill the tank?
Answer:
96 minutes
Step-by-step explanation:
Time taken by 6 pipes to fill a tank = 80 minutes
Time taken by 1 pipe to fill a tank = 80×6 = 480 minutes
Tim taken by 5 pipes to fill a tank = 480/5 = 96 minutes
Answer:
66 min and 7 seconds

4 divided by 34 how do you divide that to get a remainder
Answer:
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 4 on the left side and the dividend 34 on the right side like this:
4 ⟌ 3 4
Step 2:
The divisor (4) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:
0
4 ⟌ 3 4
Step 3:
Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.
0
4 ⟌ 3 4
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.
0
4 ⟌ 3 4
- 0
3
Step 5:
Move down the 2nd digit of the dividend (4) like this:
0
4 ⟌ 3 4
- 0
3 4
Step 6:
The divisor (4) goes into the bottom number (34), 8 time(s). Therefore, put 8 on top:
0 8
4 ⟌ 3 4
- 0
3 4
Step 7:
Multiply the divisor by the result in the previous step (4 x 8 = 32) and write that answer at the bottom:
0 8
4 ⟌ 3 4
- 0
3 4
3 2
Step 8:
Subtract the result in the previous step from the number written above it. (34 - 32 = 2) and write the answer at the bottom.
0 8
4 ⟌ 3 4
- 0
3 4
- 3 2
2
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 34 divided by 4 calculated using Long Division is:
8
2 Remainder
Answer:
4 remainders
Step-by-step explanation:
Here we will show you step-by-step with detailed explanation how to calculate 4 divided by 34 using long division.
Before you continue, note that in the problem 4 divided by 34, the numbers are defined as follows:
4 = dividend
34 = divisor
Step 1:
Start by setting it up with the divisor 34 on the left side and the dividend 4 on the right side like this:
3 4 ⟌ 4
Step 2:
The divisor (34) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
3 4 ⟌ 4
Step 3:
Multiply the divisor by the result in the previous step (34 x 0 = 0) and write that answer below the dividend.
0
3 4 ⟌ 4
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
3 4 ⟌ 4
- 0
4
You are done.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 4 divided by 34 calculated using Long Division is:
0
4 Remainder
