(5k-3)9+k) what is the value of k
Answer:
Set the factors equal to 0.
(5k - 3)(9 + k) = 0
The zero product property states that if two terms being multiplied have a product of zero, then at least one of them must be zero. In our case, this means we can set both (5k - 3) and (9 + k) equal to 0:
5k - 3 = 0
5k = 3
k = 3/5
9 + k = 0
k = -9
The value of k is 3/5 and -9.

We can solve it, but we can't actually use the interactive system they want you to use. Let's see if we can guide you through it.
My guess is you can control the lines by dragging the two points on the line.
Let's make the green line y = 2x + 3
When x=0 we get y=3, point (0,3). That's the y intercept, 3 up on the y axis. Drag one green point there.
When x=2 we get y=7, point (2,7), two to the right, seven up. Drag the other green point there. The green line is now y = 2x + 3.
Similarly the red line is made y = -3x + 3. When x=0, y=3, point (0,3). [Surprise!] When x=2, y=-3, point (2,-3). Drag the red points to (0,3) and (2,-3).
We already saw where they meet, at (0,3), x=0, y=3, the y intercept of both lines.

Step-by-step explanation:
The inside of a triangle equals 180 and so you subtract the other two values(100 and 30) to 180 and you get 50.
Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180
A+B+C = 180
A + 100+ 30 = 180
A + 130= 180
Subtract 130 from each side
A+130-130= 180-130
A = 50
Which equation represents the graph? (y-1)^2/49-x^2/81=1 (y-1)^2/7-x^2/9=1

The given equations are both hyperbola equations with the center shifted to (0,1). They represent different graphs due to differences in their denominators. Hyperbola equations result in a graph of two separate curves, each one a mirror image of the other.
Explanation:The equations (y-1)^2/49-x^2/81=1 and (y-1)^2/7-x^2/9=1 are both in the form of the hyperbola equation. This type of equation represents a graph that consists of two separate curves, each one a mirror image of the other, positioned about a central point called the center of the hyperbola. In these particular equations, the center of the hyperbola is shifted from the origin to the point (0,1).
Hyperbola equations are generally in the form (x-h)^2/a^2 - (y-k)^2/b^2 = 1 or (y-k)^2/a^2 - (x-h)^2/b^2 = 1
However, even though these equations are in the form of hyperbolas, they do not represent identical graphs. In the first equation, the y term is divided by 49 and the x term by 81, whereas in the second, these denominators are 7 and 9. These denominator values affect the shape and orientation of the hyperbolae, leading to different graphical representations for each equation.

and g(x) = 150-0.001x² models the service cost per item. Write a function C(x) for the total manufacturing and
service cost per item.
Answer:
Profit is calculated by subtracting the total cost from the total revenue as expressed in the equation given above as,
P(x) = R(x) - C(x)
If we are to substitute the given expression for each of the terms, we have,
P(x) = x(S(x)) - C(x)
Substituting,
P(x) = x(30 - 0.01x) - (0.15x³ + 0.01x² + 2x + 120)
Simplifying,
P(x) = 30x - 0.01x² - 0.15x³ - 0.01x² - 2x - 120
Combining like terms,
P(x) = -0.15x³ - 0.02x² + 28x - 120

Step-by-step explanation:
Final answer:
To find the total cost function C(x), you combine the manufacturing cost function f(x) = 1000 - 0.01x² and the service cost function g(x) = 150 - 0.001x², resulting in C(x) = 1150 - 0.011x².
Explanation:
To create a function C(x) for the total manufacturing and service cost per item, you will simply add the manufacturing cost function f(x) and the service cost function g(x) together. The provided functions are f(x) = 1000 - 0.01x² for the manufacturing cost per item and g(x) = 150 - 0.001x² for the service cost per item.
When you add these two functions, you get:
C(x) = f(x) + g(x)
= (1000 - 0.01x²) + (150 - 0.001x²)
= 1150 - 0.011x²
This new function, C(x), represents the total cost per item when x items are produced, encompassing both manufacturing and service costs.
jordan purchased 30 bags of candy for $12. At that rate how many bags of candy can he purchase for $8
Answer:
45 bags of candy
Step-by-step explanation:
The first thing is to calculate the money Jordan has, we know that by multiplying the number of bags by their price, that is:
30*12 = 360
I mean, he's got $360, now with this money he wants to buy $8 bags, so it would be
360/8 = 45
That means I could buy 45 bags of candy if they cost $8
Jordan can purchase 20 bags of candy for $8.
Jordan purchased 30 bags of candy for $12. At that rate, to find out how many bags of candy he can purchase for $8, we first calculate the cost per bag of candy by dividing the total cost by the number of bags purchased. This gives us a rate of $0.40 per bag of candy ($12/30 = $0.40). To determine how many bags of candy Jordan can purchase for $8, we then divide $8 by the cost per bag, which is $0.40.
Calculating, $8/$0.40 = 20 bags of candy. Thus, for $8, Jordan can purchase 20 bags of candy at the same rate.

The circumference of a circle is 36cm what is the radius?
Answer:
About 5.73 cm
Step-by-step explanation:
C=2πr so
36=2πr (divide by 2)
18=πr (using 3.14 as π)
18=(3.14)r (divide by 3.14)
r=5.732484076 so
R≈5.73 cm
Final answer:
The radius of a circle with a circumference of 36cm is approximately 5.73cm, calculated by dividing the circumference by the product of 2 and Pi (
).
Explanation:
Calculating the Radius from the Circumference
The circumference of a circle is closely related to its radius through the mathematical constant which is approximately 3.14159. The circumference (C) can be expressed using the formula C = 2
r, where r is the radius. Given that the circumference is 36cm, we can rearrange the formula to solve for the radius: r = C / (2
r). Substituting the given circumference into the equation, we get:
r = 36cm / (2
3.14159)
By performing the division, we can find the radius of the circle:
r = 36cm / (2 * 3.14159)
r = 36cm / 6.28318
r ≈ 5.73cm
Therefore, the radius of the circle is approximately 5.73cm.

Laisha drew a model on grid paper of a decorator tile that she wants to buy. Each grid line represents 5 cm. Her drawing has coordinates (3, 4), (5, 10), (7, 4), and (5, 0). Calculate the area of the real tile.
Answer:
The area of the real tile is 20 cm².
Step-by-step explanation:
Plot the points provided on a graph using grid line representing 5 cm each as follows.
The diagram below shows that the model of the tile is in the shape of a kite.
The area of a kite is:
[tex]\text{Area of a Kite}=\frac{p\times q}{2}[/tex]
Here, p and q are the two diagonals.
The measure of diagonals p and q are:
p = 10 cm
q = 4 cm
Compute the area of the kite as follows:
[tex]\text{Area of a Kite}=\frac{p\times q}{2}[/tex]
[tex]=\frac{10\times 4}{2}\\\\=10\times 2\\\\=20[/tex]
Thus, the area of the real tile is 20 cm².
Laisha's tile, represented by a rhombus with coordinates (3, 4), (5, 10), (7, 4), (5, 0) on a grid where each line is 5 cm, has a real area of 250 square centimeters, calculated using the formula for the area of a rhombus.
The student is asking about calculating the area of a geometric shape based on its coordinates on a grid. To find the real area of Laisha's tile, we need to determine the shape represented by the given coordinates (3, 4), (5, 10), (7, 4), and (5, 0). Noting that each grid line represents 5 cm, it appears that the shape is a diamond or a rhombus, and we can calculate the area by finding the product of the lengths of the diagonals (the distance between (3, 4) and (7, 4) and the distance between (5, 10) and (5, 0)) divided by two.
The length of one diagonal is simply the distance between (3, 4) and (7, 4), which is 4 grid units, or 4 x 5 cm = 20 cm. The length of the other diagonal is the distance between (5, 10) and (5, 0), which is 10 grid units, or 10 x 5 cm = 50 cm. The formula for the area of a rhombus is (d1 x d2) / 2, where d1 and d2 are the lengths of the diagonals. Plugging in our values, we get (20 cm x 50 cm) / 2 = 500 [tex]cm^2[/tex] / 2 = 250 [tex]cm^2[/tex].
The real area of the tile is thus 250 square centimeters.
