The graph below show the proportional relationship between the number of cops of milk and the number of cups of strawberry juice in a recipe of homemade strawberry milk

Answer:

yes

Step-by-step explanation:

If the graph of a relationship is a line or a ray through the origin, then it is proportional. If it is a line or ray that does not pass through the origin, then it is not proportional. Also, if it is not linear, then it is not proportional.

The value of x that would make triangle ABC a right triangle is x= 2. The justification is that the product of the slopes of two perpendicular lines is -1/2, and when the points are plugged into the distance formula, the sides satisfy the Pythagorean theorem.

To determine a value of x that would make triangle ABC a right triangle, we need to check if the square of the length of any two sides equals the square of the length of the third side.

We can use the distance formula to find the lengths of the sides of the triangle

AB = √((x + 3)² + 4²)

BC = √(2² + 3²)

CA = √((x + 1)² + 1²)

To make triangle ABC a right triangle, we need to find a value of x that satisfies the Pythagorean theorem

AB² + BC² = CA²

[(x + 3)² + 4²] + [2² + 3²] = [(x + 1)² + 1²]

Simplifying this equation yields

x² + 2x - 8 = 0

Solving for x, we get

x = 2 or x = -4

So, if x = 2 or x = -4, then triangle ABC is a right triangle.

To justify this, we can find the slopes of the line segments connecting the vertices of the triangle

mAB = (3 - (-1)) / (x - (-3)) = 4 / (x + 3)

mBC = (-4 - (-1)) / (-1 - (-3)) = -3/2

mCA = (3 - (-4)) / (x + 1 - (-1)) = 7 / (x + 2)

When x = 2, we get

mAB = 4/5

mBC = -3/2

mCA = 7/3

mAB * mBC = -2/5

mBC * mCA = -7/6

mCA * mAB = 14/15

when x = 2, triangle ABC is right triangle.

When x = -4, we get

mAB = 4/(-1) = -4

mBC = -3/2

mCA = 7/(-3) = -7/3

mAB * mBC = 6

mBC * mCA = 14/3

mCA * mAB = 7/2

when x = -4, triangle ABC is not a right triangle.

Answer:

Step-by-step explanation:

Katy traveled more distance than Roger by 84.9 miles.

Subtraction is a basic arithmetic operation that involves finding the difference between two numbers, by taking away one number from another. It is denoted by the minus (-) sign and is the inverse operation of addition

To find out who traveled more distance, we need to calculate the difference between the distance traveled by Roger and Katy.

So, Katy traveled 205.65 miles and Roger traveled 120.75 miles.

To find out who traveled more, we subtract the distance traveled by Roger from the distance traveled by Katy

= 205.65 miles - 120.75 miles

Subtract the numbers

= 84.9 miles

Therefore, Katy traveled 84.9 miles more than Roger.

Lakeside Olds should expect to have approximately 3 automobiles lined up at opening time on a typical day based on the probability distribution provided.

To find the expected number of automobiles lined up at the Lakeside Olds dealer at opening time, we use the concept of expected value. The expected value is the average value we would expect to see if we repeated the experiment many times. In this case, the experiment is the number of automobiles lined up at the dealer at opening time.

We are given the probability distribution for the number of automobiles, which tells us the probability of each possible outcome. We use these probabilities to calculate the expected value as the weighted average of all possible outcomes.

Expected number of automobiles = (1 x 0.05) + (2 x 0.30) + (3 x 0.40) + (4 x 0.25)

= 0.05 + 0.60 + 1.20 + 1.00

A 11.544 acre-feet of this ice field will melt from the beginning of day 1 (t = 0) to the beginning of day 4 (t = 3). So, correct option is C.

To solve the problem, we need to integrate the given rate of melting with respect to time over the interval [0,3] to find the total amount of ice that melts during this time.

First, we can simplify the given rate of melting by using the identity: sin³(t) = (3sin(t) - sin(3t))/4

So, M(t) = 4 - (3sin(t) - sin(3t))/4 = 16/4 - 3sin(t)/4 + sin(3t)/4 = 4 - 0.75sin(t) + 0.25sin(3t)

Integrating this expression with respect to t over the interval [0,3], we get:

[tex]\int\limits^3_0[/tex] M(t) dt = [tex]\int\limits^3_0[/tex] (4 - 0.75sin(t) + 0.25sin(3t)) dt

= [4t + 0.75cos(t) - (1/3)cos(3t)]|[0,3]

= (12 + 0.75cos(3) - (1/3)cos(9)) - (0 + 0.75cos(0) - (1/3)cos(0))

Answer:

The surface area of the square pyramid is approximately 28.2 square units.

Explanation:

The base area and the areas of each triangle face must be determined to calculate the surface area of a square pyramid.

Since the base is a square with four units for each edge, its area is:

The base area equals 42 to 16 square units.

We must determine the length of the slant height, which is the height of each triangular face, to get the area of each triangle.

The Pythagorean theorem may be used to get the slant height: a2 + h2 = s2,

where an equals half the base's length (2 units), h is similar to the pyramid's size (3 units), and s is the slant height.

Inputting the values, we obtain:

2^2 + 3^2 = s^2

4 + 9 = s^2

13 = s^2 s = √13

Using the following formula, we can now get the area of each triangle face:

The area of the triangular face equals 0.5 base height, where the base is the slant height (13 units), and the size is the square base's edge length (4 units).

The triangular face area equals 0.5 x 4 x 13 = 213 square units.

Given that there are four triangular faces, their combined area is:

Units of area: 4 x 2 x 13 = 8 x 13

The total surface area is then calculated by summing the base and triangle face areas:

Base area plus triangle face area equals total surface area.

Surface area total = 16 + 8 x 13

28.2 square units total surface area (rounded to the nearest decimal point)

Therefore, the square pyramid's surface area is around 28.2 square units.

Neither student's work properly verifies the identity and  csc x = 1/sin x,  sin² x + cos² x = 1 are the  two identities that were used in Student A's verification.

Part A:

Both Student A and Student B did not verify the identity properly. Student A started with the correct expression, but then manipulated it incorrectly.

In Step 1, multiplying cosine x over sine x times cosine x does not equal cosecant x minus sine x.

In Step 2, dividing cosine squared x by sine x also does not equal cosecant x minus sine x. Student B also started with the correct expression, but made a mistake in Step 2.

Subtracting sine squared x over sine x from 1 does not equal 1 over sine x minus sine squared x over sine x.

Therefore, neither student's work properly verifies the identity.

Part B:

Identity 1: csc x = 1/sin x

Student A uses this identity in Step 4 when they rewrite 1/sin x as csc x.

Identity 2: sin² x + cos² x = 1

Student A uses this identity in Step 3 when they rewrite cos² x as 1 - sin²x.

The first four terms of the geometric sequence are -1, 11, -121, and -1210.

We have,

To find the first four terms of the geometric sequence, we need to determine the common ratio, r, and then use it to calculate the other terms.

We can start by using the formula for the nth term of a geometric sequence:

an = a1 x r^(n - 1)

where an is the nth term, a1 is the first term, r is the common ratio, and n is the position of the term we want to find.

Since we are given a2 and a3, we can use them to form two equations:

a2 = a1 x r

a3 = a1 x r²

We can then solve for a1 and r:

a1 = a2 / r = 11 / r

r = a3 / a2 = -121 / 11

Substituting these values into the formula for the nth term, we get:

an = (11 / r) x (-121 / 11)^(n - 2)

Simplifying this expression, we get:

an = -11 x 11^(n - 2)

Now we can calculate the first four terms:

a1 = 11 / r = 11 / (-121 / 11) = -1

a2 = 11

a3 = -121

a4 = -11 x 11^(4 - 2) = -1210

The probability of selecting a person who wears a watch given that they wear a ring is 2/5 or 0.4.

From the Venn diagram, we can see that there are 10 people who wear rings, 2 of whom also wear watches. This means that the probability of randomly selecting a person who wears a ring is 10 out of the total number of people in the class. That is:

P(Ring) = 10 / (10+2) = 10/12

Similarly, we can find the probability of selecting a person who wears both a watch and a ring. From the diagram, we can see that there are 4 such people. Thus,

P(Watch and Ring) = 4 / (10+2) = 4/12

Using the formula for conditional probability, we get:

P(Watch|Ring) = P(Watch and Ring) / P(Ring)

The linear function f with the values f(10) = 5 and f(2) = -3 is f(x) = x - 5.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

hence, to write a linear function f with the values f(10) = 5 and f(2) = -3, we need to find the slope and y-intercept of the function.

The slope of a linear function can be found by using the formula:

Slope m = (y2 - y1) / (x2 - x1)

Using the values of f(10) = 5 and f(2) = -3,

we can find the slope:

Slope m = (5 - (-3)) / (10 - 2)

= 8 / 8

= 1

Now that we have the slope, we can use the point-slope form to find the equation of a line:

y - y1 = m(x - x1)

Where m is the slope and (x1, y1) is one of the points on the line.

Using the point (10, 5) and slope m = 1, we have:

y - y1 = m(x - x1)

y - 5 = 1(x - 10)

Simplifying, we get:

y - 5 = x - 10

y = x - 5

f(x) = x - 5

Therefore, the linear function is f(x) = x - 5.
