Answer:

Step-by-step explanation:

Actually, none of the posted possible answers is correct.  The slope of the horizontal line is zero, whereas the slope of the given equation is 8.  There is no number which, when multiplied by 0, results in a non-zero product.

However, if we are ADDING instead of multiplying, then the correct number is 8, because 0 + 8 = 8.

ANSWER: 60 female lions

In the ratio there are 21 male lions and 20 female lions, in total 41 lions. Create a proportion relating the total number of lions in the ratio (41) and in the problem (123), and the number of female lions in the ratio (20) and in the problem (unknown).

20/41 = x/123

Cross multiply and solve

20(123)=41x

2460=41x

60=x

Answer:

X=20. Our x coordinate is 20.

Step-by-step explanation:

Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.

2(4)= x-12

8+12 =x

X=20.

Answer:

20

Step-by-step explanation:

since the line has a slope of 1/2, the x coefficient of the line is 1/2. Since the y intercept is -6, we have the equation of the line

x/2 - 6 = y

Since in this case y = 4, we have

x/2 - 6 = 4

x/2      = 10

x          = 20

So the x coordinate is 20 when the y coordinate is 4.

Answer:

Final answer is  [tex]a_0=-9[/tex]

Step-by-step explanation:

Given equation is [tex]5-a_0=14[/tex]

Now we need to solve the given equation [tex]5-a_0=14[/tex] for the unknownd variable  [tex]a_0[/tex] .

We can do that by isolating [tex]a_0[/tex]

To isolate [tex]a_0[/tex], let's subtract 5 from both sides

[tex]5-a_0-5=14-5[/tex]

[tex]-a_0=9[/tex]

multiply both sides by -1

Answer:

[tex]f(x)=\frac{1}{4}x-4[/tex]

Step-by-step explanation:

To find the equation of a linear function , we pick two points from the graph

LEts pick two points (0,-4) and (4,-3)

Equation of linear function is [tex]f(x)=mx+b[/tex]

where m is the slope and b is the y intercept

[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]

(0,-4) is (x1,y1) and (4,-3) is (x2,y2)

Answer:

4 packages of fruits, 5 packages of chocolate

Step-by-step explanation:

We need to find the lowest common multiple of 12 and 15.

12 is ( 2 * 2 * 3) and 15 is (5 * 3).

The lowest common multiple would be three.

Then we can multiply 12 by 5 and 15 by 2 * 2.

The are both equal to 60.

Then we divide:

60 / 15 = 4, which is the amount of packages for the fruits

60/ 12 = 5, the packages of chocolates.

IF THIS WAS NOT THE ANSWER YOU WERE LOOKING FOR, PLEASE COMMENT.

To find the smallest number of packages needed to have the same amount of both fruit and chocolate pastries, calculate the LCM of 15 and 12, which is 60. Thus, one needs 4 fruit pastry packages and 5 chocolate pastry packages.

The student's question relates to finding the least common multiple (LCM) of two numbers, in this case, the number of pastries in each package. Mrs. Patterson's bakery sells fruit pastries in packages of 15, and chocolate pastries come in packages of 12. To find how many of each type of package one needs to buy to get the same number of both types of pastries, we need to calculate the LCM of 15 and 12.

The LCM of 15 and 12 is 60. This means the smallest number of fruit pastry packages (of 15) needed is 60 / 15, which equals 4. Similarly, the smallest number of chocolate pastry packages (of 12) needed is 60 / 12, which equals 5. Therefore, the person would need to buy 4 fruit pastry packages and 5 chocolate pastry packages to have an equal number of pastries.

Answer:

w = 21.4 ft

Step-by-step explanation:

Area of Trapezoid = Area = (a+b)/2 * h

Where a and b are the bases of trapezoid, and h is the height.

In the figure we are given:

a= 32.3 ft

b=w=?

h= 22.9 ft

Area = 614.865 ft²

Putting values in formula

Area = (a+b)/2 * h

614.865 = (32.3 + w) / 2 * 22.9

1229.73 = 32.3 + w * 22.9

1229.73 / 22.9 = 32.3 +w

53.7 -32.3 = w

=> w = 21.4 ft

Answer:

a(n) = 12 * (13)^(n-1)

Step-by-step explanation:

First step is to determine what's the scale/multiplication factor between each term:

156 / 12 = 13

2028 / 156 = 13

So, since we got 13 between 1st, 2nd and 3rd term, we can be confident it's the right multiplication factor.

an would be the first term (12) multiplied by a factor of 13. So,

[tex]an = 12 * (13)^{n-1}[/tex]

If we try for n > 1, we have

a(2) = 12 * (13)^(2-1) = 12 * 13 = 156

a(3) = 12 * (13)^(3-1) = 12 * 13² = 12 * 169 = 2028

It matches!

Answer:

f(x) reflect over the x-axis, vertically stretch by a factor 3, and

shift down 1 unit ⇒ 2nd answer

Step-by-step explanation:

* To solve this problem you must to know some fact about

  transformation

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

- A vertical stretching is the stretching of the graph away from

 the x-axis

• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically

 stretched by multiplying each of its y-coordinates by k.

- A vertical compression is the squeezing of the graph toward

 the x-axis.

• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed

 by multiplying each of its y-coordinates by k.

• if k should be negative, the vertical stretch or compress is

 followed by a reflection across the x-axis.  

* Now lets solve the problem

- From the graph

∵ The line passes through the points (0 , -1) and (-1 , 2)

∴ The slope of the line = (2 - -1)/(-1 - 0) = 3/-1 = -3

∵ The graph intersect the y-axis at point (0 , -1)

∵ The equation of any line ⇒ y = mx + c , where m is the slope

   of the line and c is the y-intercept

∵ m = -3 and y-intercept = -1

∴ y = -3x - 1 ⇒ g(x) = -3x - 1

∵ f(x) = x

* From all the transformation above

# -3x means the graph reflected over the x-axis, vertically stretch

  by a factor 3

# -1 means shift down 1 unit

# g(x) = -3f(x) - 1

∴ f(x) reflect over the x-axis, vertically stretch by a factor 3, and

  shift down 1 unit

Answer:

B. 1

Step-by-step explanation:

Your answer for A is correct.

The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.

The sub started to get lowered at x = 0.

Now we need to solve for the smallest positive zero of the function.

This function factors to (x - 1)(x - 7)

From this we can tell that the submarine is a water level for time x = 1 and x = 7.

The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.

The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.
