Given the function I need to evaluate question a)

One true statement about the equation is that if Albert continues to follow his diet and exercise plan, his weight will decrease by 5 pounds per week. Another true statement is that if x is zero, which represents the start of his diet and exercise plan, his weight will be 250 pounds.

An equation is a mathematical statement that shows that two expressions are equal. It typically consists of two sides, a left-hand side and a right-hand side, connected by an equal sign "=". The expressions on either side of the equal sign can be numbers, variables, or combinations of both.

Here,

The equation y = 250 - 5x represents a linear model that describes the relationship between Albert's weight (y) and the number of weeks he has been dieting and exercising (x).

The coefficient of x in the equation is -5, which indicates that Albert is losing weight at a rate of 5 pounds per week. The y-intercept of the equation is 250, which represents Albert's initial weight before he started dieting and exercising.

Answer:

19

Step-by-step explanation:

The two values are equal to each other because they are vertically symmetrical (i forgot the term, havent dine this in a while) so 3x-3 = [6(x - 10)] so to simplify this, you could say 6x - 60 = 3x-3, which makes it a lot more understandable. To find x, add 60 to both sides and tou should come out with 6x = 3x + 57, we now subtract 3x from both sides to get 3x = + 57, divide by three then you get the balue of x, which is 19

Answer: We know that the function f(x) is an exponential function. An exponential function can be written in the form:

f(x) = a * b^x

where:

a = the initial value (when x = 0)

b = the base of the exponential function

x = the independent variable

To find the values of a and b, we can use the given information:

f(1) = 8, so:

8 = a * b^1

8 = a * b

f(10.5) = 72, so:

72 = a * b^10.5

We can now use the first equation to solve for a:

a = 8/b

Substituting this value into the second equation, we get:

72 = (8/b) * b^10.5

Simplifying:

72 = 8 * b^9.5

9 = b^9.5

b = 9^(1/9.5)

b = 1.4608 (approx.)

Substituting the values of a and b into the exponential function, we get:

f(x) = 8 * 1.4608^x

Now we can find f(3.5):

f(3.5) = 8 * 1.4608^3.5

f(3.5) = 8 * 6.2797

f(3.5) = 50.2376 (approx.)

Therefore, f(3.5) is approximately equal to 50.24.

For the given triangles,  EF/EI=DF/HI and also ED/EH=DF/HI.

What is a triangle's definition?

A triangle is a closed two-dimensional shape with three straight sides, three angles, and three vertices (or corners). It is formed by connecting three non-collinear points in a plane with straight lines. The sum of the interior angles of a triangle is always 180 degrees, and each exterior angle is equal to the sum of its two adjacent interior angles. Triangles can be classified based on the length of their sides and the size of their angles, such as equilateral, isosceles, scalene, acute, right, and obtuse triangles.

Now,

As given triangle are similar by SSS.

that means ratio of respective sides will be equal.

Then,  ED/EH=EF/EI=DF/HI

Answer: The surface area of the rectangular prism is 1356 square meters.

Step-by-step explanation:

The surface area of a rectangular prism is given by the formula:

SA = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we get:

SA = 2(16m)(19m) + 2(16m)(2m) + 2(19m)(2m)

SA = 1216m^2 + 64m^2 + 76m^2

SA = 1356m^2

Therefore, the surface area of the rectangular prism is 1356 square meters.

The tensions in the string are approximately 37.5 lb and 57.39 lb for T1 and T2, respectively.

Tension is the force that is transmitted through a string, rope, cable, or any other object that is pulled taut by a force. It is a pulling force that is exerted on an object by the string or cable that is attached to it. Tension is a scalar quantity, meaning that it has a magnitude but no direction.

The tension in a string or cable depends on several factors, including the strength and stiffness of the material, the angle at which the string is attached to the object, and the amount of force applied to the string. In general, the tension in a string is equal to the force applied to the string, divided by the cross-sectional area of the string.

To find the tensions T1 and T2 in the string, we can use trigonometry and the fact that the weight is in equilibrium (i.e., not moving).

First, we can use the fact that the weight is in the middle of the string to split the weight into two equal components, one pulling on each end of the string.

The weight component pulling on T1 can be found by multiplying the weight by the sine of the angle between T1 and the horizontal:

W1 = (75 lb) * sin(50°)

W1 ≈ 57.39 lb

Similarly, the weight component pulling on T2 can be found by multiplying the weight by the sine of the angle between T2 and the horizontal:

W2 = (75 lb) * sin(30°)

W2 ≈ 37.5 lb

Since the weight is in equilibrium, the tensions in the string must be equal and opposite to these weight components:

T1 = W2 ≈ 37.5 lb

T2 = W1 ≈ 57.39 lb

Therefore, the tensions in the string are approximately 37.5 lb and 57.39 lb for T1 and T2, respectively.

The value of z is solved using the concept of supplementary angles since and z and angle 65 degrees are supplementary angles hence we have that

z + 65 = 180

z = 180 - 65

z = 115 degrees

Also angle 6x - 23 degrees and angle z are equal according to the alternate internal angle theorem

hence we have that

What is the distributive property of multiplication?

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

To multiply (4x + 2)(3x² - 5x + 7), we can use the distributive property of multiplication:

(4x + 2)(3x² - 5x + 7) = 4x(3x² - 5x + 7) + 2(3x² - 5x + 7)

Now we can simplify each term:

4x(3x² - 5x + 7) = 12x³ - 20x² + 28x

2(3x² - 5x + 7) = 6x² - 10x + 14

Putting the terms together, we get:

(4x + 2)(3x² - 5x + 7) = 12x³ - 20x² + 28x + 6x² - 10x + 14

Simplifying further:

(4x + 2)(3x² - 5x + 7) = 12x³ - 14x² + 18x + 14

Step-by-step explanation:

The probability that Nora will pick a yellow quartz piece on the next selection is 1/9.

To calculate the probability of picking a yellow quartz piece on the next selection, we need to analyze the frequency of yellow quartz pieces relative to the total number of recorded quartz pieces.

Out of the 18 quartz pieces Nora picked, only 2 were yellow.

To find the probability, we divide the number of yellow quartz pieces by the total number of pieces recorded:

Probability = Number of yellow quartz pieces / Total number of recorded pieces

The number of yellow quartz pieces is 2, and the total number of recorded pieces is 18.

So the probability can be calculated as:

Probability = 2 / 18

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2 in this case:

Probability = 1 / 9

It's important to note that this probability assumes the picking process is random and that the distribution of colors in the giant box of quartz pieces remains constant over time.

Given equations : 5x+y=7

                             20x+2=y

We can solve it by using substitution method:

Now, we have 5x+y=7

it can be written as,

         y = 7 - 5x .... equation 1

Similarly, we have 20x+2=y

can be written as,

           y = 20x+2 ..... equation 2

Subtracting equation 1 from equation 2

we get,  20x+2 - ( 7 - 5x ) = 0

             20x + 5x + 2 - 7 = 0

Answer: Let's break down the total cost of dinner into three components: the cost of the meal itself (M), the sales tax (T), and the tip (P).

We know that the sales tax is 8% of the meal cost, so we can write:

T = 0.08M

We also know that the tip is 20% of the total cost, which is the sum of the meal cost and the sales tax, so we can write:

P = 0.20(M + T) = 0.20(M + 0.08M) = 0.20(1.08M) = 0.216M

Finally, we know that the total cost of dinner must be no more than $30, so we can write:

M + T + P ≤ 30

Substituting the expressions for T and P that we derived earlier, we get:

M + 0.08M + 0.216M ≤ 30

Simplifying and solving for M, we get:

1.296M ≤ 30

M ≤ 23.15

Therefore, the most expensive item you can order is $23.15 or less (before tax and tip) to stay within your budget of $30.
