Answer:

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

Let's call the number x. The statement tells us that

x^2 - 10 = 3x, or

x^2-3x-10 = 0

Factoring:

(x-5)(x+2) = 0. Here, we see that there are two solutions: x = 5 and x = -2. So, the negative solution is x = -2.

Answer:

Step-by-step explanation:

From the given information:

(a)

Since growth quantity is not continuous

[tex]Q(t) = 150 (1.07)^t[/tex]

For t = 10

[tex]Q(10) = 150 (1.07)^{10}[/tex]

[tex]\mathbf{Q(10) = 295.073}[/tex]

(b)

Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.

i.e.

[tex]Q(t) = 150 e^{0.07t}[/tex]

At t = 10 for a continuous growth rate;

[tex]Q(10) = 150 e^{0.07 \times 10}[/tex]

[tex]Q(10) = 150 e^{0.7}[/tex]

[tex]\mathbf{Q(10) = 302.063}[/tex]

Answer:

125

Step-by-step explanation:

r= .5 (each term is being mulitplied by .5 to get the next one

We have

32,000*(.5)^(9-1)

32,000*(.5)^8

Answer:

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]

Step-by-step explanation:

I notice you have a dx at the end of the equation, this leads me to believe this is an integral. With no bounds of integration, I will solve for the indefinite integral. I will also interpret your equation as follows:

[tex]\int \:2+5x+\frac{1}{2}x^3dx[/tex]

Sum rule tells us:

[tex]\int \:2dx+\int \:5xdx+\int \frac{1}{2}x^3dx[/tex]

From this we get:

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}[/tex]

Don't forget to add the constant!

[tex]2x+\frac{5x^2}{2}+\frac{x^4}{8}+C[/tex]

Answer:

X>9

Step-by-step explanation:

Move all terms not containing x to the right side

7x>63

divide each term by 7 and simplify

7x/7 >63/7

cancel the common factor of 7

x>63/7

divide 63 by 7 x>9

x>9

Answer:26

Step-by-step explanation:60 minus 6, equals 52. you need to do 60-6 to get the twice the sum of a number. divide 52 by 2, since its twice the sum of a number. 52 divided by 2 is 26. you can check your answer by doing 26 times 2 plus 6, and get 60.

Answer:

x = 20

Step-by-step explanation:

x + 2x + (x + 10) = 90° (right angle)

x + 2x + x + 10 = 90

Add like terms

4x + 10 = 90

4x = 90 - 10 (substraction property of equality)

4x = 80

x = 80/4 (division property of equality)

x = 20

The updated IQR is 14.54.

Step-by-step explanation:

The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.

This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee.

This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 5.

Step-by-step explanation:

Answer: b(n)=10-4n for n >1

The function a(n) = 10 – 4n for n > 0 generates the given arithmetic sequence.

"It is a number sequence with a common difference between successive terms."

For given example,

Given arithmetic sequence: 6, 2, -2, -6, . . .

Here, 2 - 6 = -4

-2 - 2 = -4

-6 - (-2) = -4

This means, the common difference is d = -4

If n is a positive integer, then the function a(n) = 10 - 4n (n > 0) generates given sequence.

For n = 1

⇒ a(1) = 10 - 4(1)

⇒ a(1) = 6

For n = 2,

⇒ a(2) = 10 - 4(2)

⇒ a(2) = 2

For n = 3,

⇒ a(3) = 10 - 4(3)

⇒ a(3) = -2

For n = 4,

⇒ a(4) = 10 - 4(4)

⇒ a(3) = -6

Therefore, the function a(n) = 10 – 4n for n > 0 generates the given arithmetic sequence.

Answer:

Step-by-step explanation:

y = -2x - 5.....slope here is -2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we will need is : 1/2. See how I flipped the slope of -2/1 and changed it to -1/2.....now I change the sign making our new slope be 1/2.

y = mx + b

slope(m) = 1/2

(-1,-2).....x = -1 and y = -2

now sub and find b, the y int

-2 = 1/2(-1) + b

-2 = -1/2 + b

-2 + 1/2 = b

-4/2 + 1/2 = b

-3/2 = b

so ur perpendicular line is : y = 1/2x - 3/2

Answer:

y = -2x - 5

m = -2

Step-by-step explanation:

The perpendicular line has a negative reciprocal slope.

m = 1/2

You are also given a point, so use the point slope formula.

y - y1 = m(x - x1)

y + 2 = 1/2(x + 1)

y + 2 = 1/2x + 1/2

y = 1/2x - 3/2

So the line perpendicular to y = -2x - 5 in slope intercept form is:

y = 1/2x - 3/2

or

y = 0.5x - 1.5
