Answer:

Step-by-step explanation:

Amy = x years

Ben = x + 2  (years)

Alice = x - 6 (years)

Answer:

a)

Amy's age is x.

• Ben's age is 2 more than Amy's age.

∴ Ben's age = x + 2

• Alice's age is 6 less than Amy's age.

∴ Alice's age = x - 6

A pair of points which is perpendicular to line L is: D. (3, -5),(-6, 3).

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For points A, we have:

[tex]Slope = \frac{3\;-\;(-6)}{3\;-\;(-9)}\\\\Slope = \frac{9}{12}[/tex]

Slope = 9/12.

For points B, we have:

[tex]Slope = \frac{6\;-\;(-2)}{-6\;-\;(-9)}\\\\Slope = \frac{8}{-3}[/tex]

Slope = -8/3.

For points C, we have:

[tex]Slope = \frac{3\;-\;(-6)}{3\;-\;(-5)}\\\\Slope = \frac{9}{8}[/tex]

Slope = 9/8.

For points D, we have:

[tex]Slope = \frac{3\;-\;(-5)}{-6\;-\;3}\\\\Slope = \frac{-8}{9}[/tex]

Slope = -8/9.

In Mathematics, the condition for perpendicularity of two lines is:

m₁ × m₂ = -1

9/8 × 8/9 = -1

Thus, points (3,−5) and (−6,3) are perpendicular to line L.

Answer:

104

Step-by-step explanation:

women = 8/8

men = 5/8

all workers = 8/8 + 5/8 = 13/8

extra women workers = 8/8 - 5/8 = 3/8

so...

3/8 = 24

13/8 = x

( cross multiplication method)

3/8 x = 39

x = 104

Hence, there are 104 workers

Answer:

104 workers

Step-by-step explanation:

w = women

m = men = 5/8 w

w - 5/8 w = 24

w = 64      then m = 5/8 * 64 = 40        total = 104

Answer:

62

Step-by-step explanation:

1. To find the total area, we must find the area of the three individual gardens and sum them together

2. Since the gardens are square, the area is equal to the side length squared

3. Therefore, square the sides and sum:

3^2 = 9

7^2 = 49

2^2 = 4

4+9+49 = 62

=========================================================

Explanation:

The floor is a 7 meter by 5 meter rectangle. The perimeter is

P = 2(L+W)

P = 2(7+5)

P = 2(12)

P = 24

The perimeter of the floor is 24 meters.

Multiply this perimeter by the unknown height h to get 24h

This expression represents the lateral surface area. This is the combined wall area. Set this equal to 120 and solve for h.

24h = 120

h = 120/24

h = 5

-----------------

Check:

One pair of walls is 7 meters by 5 meters, giving an area of 7*5 = 35 square meters each. So far that's 2*35 = 70 square meters for these two walls combined.

The other pair of walls is 5 by 5. Each has an area of 5*5 = 25 which doubles to 2*25 = 50

The total wall area is 70+50 = 120 to confirm the answer.

The surface area of the composite shape is: 315 in.².

Surface area = surface area of square pyramid + surface area of square prism - 2(base area)

Surface area of square pyramid = Area of base + 1/2(perimeter of base × slant height) = 9² + 1/2[4(9) × 7] = 207 in.²

Surface area of square prism = 2a² + 4ah = 2(9²) + 4(9)(3)

Surface area of square prism = 2(9²) + 4(9)(3) = 270 in.².

area of triangle = base × height / 2

Base of prism: 9 in. × 9 in. = 81 in.²

4 sides of prism: 4 × 9 in. × 3 in. = 108 in.²

Equation for Determining the Number of Bacterial Cells

Initially, the count of bacterial cells = 4

It is given that the bacterial cell triples every month.

Hence, the equation for the count of bacterial cells after first month is,

a₁ = 4(3)

This count of 4(3) triples again in the second month.

So, after the second month, the equation for the count of bacterial cells is given by,

a₂ = 4(3)(3) = 4(3)²

Calculating the Count of Bacterial Cells For Each Month

Again, this count triples in the third month.

Therefore, the  equation for the count of bacterial cells after the third month becomes,

a₃ = 4(3)(3)(3) = 4(3)³

This count triples again in the fourth month and this process continues till 15 months.

Answer:

p = 3

q = 4

Step-by-step explanation:

Rotation by +90° (clockwise) about the origin:  (x, y) → (y, -x)

Therefore, (p, 4) rotated by +90° about the origin:

(p, 4) → (4, -p)

Therefore:

(4, -p) = (q, -3)

⇒ p = 3

⇒ q = 4

Therefore, (3, 4) is mapped into (4, -3) under a rotation by +90° about the origin.

Answer:

f is sometimes positive and sometimes negative on the interval

Step-by-step explanation:

So if you were to expand out the x's you would have x^2 * x * x * x which will result in x^5. and because the leading coefficient is positive, it will be going towards positive infinity as x goes towards positive infinity, and because the degree is odd the end behaviors will be opposite, so as x goes towards negative infinity the value of f(x) will be going towards negative infinity. One other thing to note is that because x^2 technically is two zeroes, with the same value, the zero at x=0 has a multiplicity of 2, meaning that it will not cross the x-axis, but rather have a turning point, once it intersects the x-axis, because the zero has an even multiplicity. Given this information we can draw a graph. So as you can see in the graph, it will sometimes be negative and sometimes positive

for this, your A might be (0,5), B (5,5), C (2,2).

parallel means railroad tracks: same slope, different intercepts.

line AB in this case has a slope of 0, intercept (0,5), so y₁=0x+5 or just y₁=5

the line passing through C also has slope 0, but intercept (0,2), so y₂=0x+2 or just y₂=2

2. perpendicular means that the slopes of two lines multiply out to -1. If line AB has, for example, a slope of 2/3, then the line passing through C would have slope -3/2 (negative reciprocal). To make things easier have either point A or B be on the x or y axis
