The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D

Step-by-step explanation:

The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where

The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)

By comparing between the form of the function and the given function

∴ m = -0.0018 ⇒ degrees per foot

∵ The sign of the slope is negative

∵ The slope = Δf(x)/Δx

- That means T(a) is decreasing function

∴ The boiling point is decreases when the altitude increasing

∵ -0.0018 = [tex]-\frac{18}{10,000}[/tex] degrees per feet

∴ The boiling point decreases by 18 degrees as the altitude

    increases by 10,000 feet or the boiling point decreases by 1.8

     degrees as the altitude increases by 1,000 feet

The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

The meaning of slope is best described by the boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet. The option (D) is correct.

To understand the meaning of the slope in the given function[tex]\( T(a) = -0.0018a + 212 \)[/tex], where [tex]\( T \)[/tex] represents the boiling point of water in degrees and [tex]\( a \)[/tex] represents the altitude in feet, we need to analyze the slope of the function.

The slope of the function is given by the coefficient of [tex]\( a \)[/tex], which is [tex]\( -0.0018 \)[/tex]. This slope tells us how the boiling point of water changes with altitude. To interpret the slope in terms of degrees per foot:

A slope of [tex]\( -0.0018 \)[/tex] means that for every 1 foot increase in altitude, the boiling point decreases by 0.0018 degrees.

To find out how much the boiling point changes over an increase of 1,000 feet in altitude, we multiply the slope by 1,000:

[tex]\( \text{Change in boiling point} = \text{slope} \times \text{change in altitude} \)[/tex]

[tex]\( \text{Change in boiling point} = -0.0018 \times 1000 \)[/tex]

[tex]\( \text{Change in boiling point} = -1.8 \)[/tex]

Therefore, the correct interpretation of the slope is that the boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet, which corresponds to option D.

The complete question is:

The boiling point of water, T (measured in degrees), at altitude a (measured in feet) is modeled by the function T(a)=-0.0018a+212. In terms of altitude and temperature, which statement describes the meaning of the slope?

A. The boiling point increases by 18 degrees as the altitude increases by 1,000 feet.

B. The boiling point increases by 1.8 degrees as the altitude increases by 1,000 feet.

C. The boiling point decreases by 18 degrees as the altitude increases by 1,000 feet.

D. The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet.

Answer:

63 pizzas

Step-by-step explanation:

In the problem it states that Sam sold half as many pizzas as Odel and sold 126 together in total. If you divide 126 pizzas by 2 or 1/2, you should get 63 pizzas for both people. Hope this helps.

The total number of frozen pizzas which Sam sell for a class fundraiser is 42 which is half as many pizzas sell by Odel.

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Sam and Odel have been selling frozen pizzas for a class fundraiser. Let the Sam has sold x number of pizzas and Odel is sold y number of pizzas.

Now it is given in the problem that, Sam has sold half as many pizzas as Odel. Thus,

[tex]x=\dfrac{y}{2}\\y=2x[/tex]                               ......1

Together Sam and Odel have sold a total of 126 pizzas. Thus,

[tex]x+y=126\\[/tex]

Put the value of y from the equaiton 1 in the above equation,

[tex]x+2x=126\\3x=126\\x=\dfrac{126}{3}\\x=42[/tex]

Hence, the total number of frozen pizzas which Sam sell for a class fundraiser is 42 which is half as many pizzas sell by Odel.

Answer: 126 and 128

Step-by-step explanation: In this problem have two consecutive even integers whose sum is 254.

Consecutive even integers can be represented as followed.

X ⇒ first even integer

X + 2 ⇒ second even integer

Since the sum of these is 254, our equation reads X + X + 2 = 254.

We can simplify on the left side of the equation to get 2x + 2 = 254.

Now, we subtract 2 from both sides of the equation to get 2x = 252.

Lastly, we will divide both sides of the equation by 2 in order to isolate x. On the left side, the 2's cancel out and on the right, 252 divided by 2 is 126.

If our first integer is 126, our next consecutive even integer will be 126 + 128 which simplifies to 254.

Therefore, our two consecutive even integers are 126 and 128.

Answer:

[tex](f+g)(x)=x^2+2x-5[/tex]

Step-by-step explanation:

Given:

The functions given are:

[tex]f(x)=2x+3\\g(x)=x^2-8[/tex]

To find: [tex](f+g)(x)[/tex]

[tex](f+g)(x)[/tex] is equal to the addition of both the functions. So, we need to add the values of both the functions and then simplify to arrive the final answer.

Therefore, [tex](f+g)(x)[/tex] is given as:

[tex](f+g)(x)=f(x)+g(x)[/tex]

Plug in the values of [tex]f(x)\ and\ g(x)[/tex] and simplify. This gives,

[tex](f+g)(x)=2x+3+x^2-8[/tex]

Combining like terms using commutative property of addition, we get

[tex](f+g)(x)=x^2+2x+3-8\\(f+g)(x)=x^2+2x-5[/tex]

Therefore, the addition of the two functions is simplified to:

[tex](f+g)(x)=x^2+2x-5[/tex]

Answer:

B

Step-by-step explanation:

If we understand 2 properties of isosceles trapezoids, then we can solve for x and y easily.

First, the two sides, "2x-13" and "x-3" are equal, as shown also by red line.

So, we equate them and find x first. Shown below:

[tex]2x-13=x-3\\2x-x=-3+13\\x=10[/tex]

Now, another property is:

Any lower base angle is supplementary to any upper base angle. That means the angle y is supplementary to "3y-4". Supplementary means that if we add up the two angles, it will be 180 degrees. So:

[tex]y+3y-4=180\\4y=180+4\\4y=184\\y=46[/tex]

From the answer choices, answer choice B is right

Part e) [tex]\$84.32[/tex]

Step-by-step explanation:

The complete question is

Rhonda deposits $5,600 in a savings account that pays 1.5% interest, compounded semi-annually. Round to the nearest cent.

a. How much interest does the account earn in the first 6 months?

b. What is the ending balance after 6 months?

c. How much interest does the account earn in the second 6 months?  

d. What is the balance after 1 year?

e. How much interest does the account earn the first year?

we know that

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

Part a) How much interest does the account earn in the first 6 months?

in this part we have  

[tex]t=6/12=0.5\ years\\ P=\$5,600\\ r=1.5\%=1.5/100=0.015\\n=2[/tex]  

substitute in the formula above

[tex]A=5,600(1+\frac{0.015}{2})^{2*0.5}[/tex]  

[tex]A=5,600(1.0075)^{1}[/tex]  

[tex]A=\$5,642[/tex]  

Find out the interest

[tex]I=A-P[/tex]

[tex]I=\$5,642-\$5,600=\$42[/tex]

Part b) What is the ending balance after 6 months?

we know that

The ending balance after 6 months is the same that the final investment value of A after 6 months

so

[tex]A=\$5,642[/tex]   ----> see part a)

Part c) How much interest does the account earn in the second 6 months?

in this part we have  

[tex]t=6/12=0.5\ years\\ P=\$5,642\\ r=1.5\%=1.5/100=0.015\\n=2[/tex]  

substitute in the formula above

[tex]A=5,642(1+\frac{0.015}{2})^{2*0.5}[/tex]  

[tex]A=5,642(1.0075)^{1}[/tex]  

[tex]A=\$5,684.32[/tex]  

Find out the interest

[tex]I=A-P[/tex]

[tex]I=\$5,684.32-\$5,642=\$42.32[/tex]

Part d) What is the balance after 1 year?

we know that

The balance after 1 year is equal to the initial deposit of $5,600 plus the  interest earned in the first 6 months plus the interest earned in the second 6 months

so

[tex]\$5,600+\$42+\$42.32=\$5,684.32[/tex]

Part e) How much interest does the account earn the first year?

The total interest the first year is equal to the interest earned in the first 6 months plus the interest earned in the second 6 months

so

[tex]\$42+\$42.32=\$84.32[/tex]

Its the Adding a quantity one or the bottom right

Adding equations is a legitimate method in solving systems because it utilizes the elimination process to simplify the system. It also respects the fundamental properties of equations and provides a precise analytical technique for finding solutions, which can be more accurate than graphical methods.

Adding equations, known as the method of elimination, is a valid method for solving a system of equations. This approach works because it leverages the property that if two equations both equal the same variable, they can be added together to eliminate one of the unknowns, simplifying the system. For instance, suppose we have equation a: x + 2y = 6, and equation b: 3x - y = 4. Adding them gets 4x + y = 10, which is a new equation that can help solve for one of the variables more directly. This takes advantage of the fact that equations describe relationships between variables that hold true under various mathematical operations, including addition.

Another key aspect is the understanding that solutions to equations are often not unique when they include an unknown squared, leading to two potential solutions. However, contextual knowledge can determine which solution is reasonable, such as in physics problems where time or velocity must make sense in the real world.

Moreover, while analytical methods of solving systems are precise, solving equations graphically can offer a visual understanding but may lack accuracy due to potential scaling and drawing inaccuracies. Therefore, analytical techniques, like adding equations, are generally more accurate but can be complemented with graphical methods for a better conceptual grasp.

The Value of t from given convex polygon is 41.

Step-by-step explanation:

Let us consider,

a=61°.

b=2t.

c=3t.

d=42°.

e=52°.

The sum of exterior angles of convex polygon is always 360°.

a+b+c+d+e=360°.

The exterior angles of any convex polygon is same as if any angle drawn inside a circle.

Steps to reform the angles:

Step 1: Draw the ∠a as given in the original diagram.

Step 2: The ∠b is adjacent to ∠a 's end and draw a parallel line of ∠b in the ∠a. The angle measure will also be same.

Step 3: Continue the same for next angles ∠c,∠d and ∠e.

(refer the image dotted lines are the parallel lines.)

⇒ 61°+42°+52°+2t+3t=360°.

155°+5t=360°.

5t=205°.

t=41°.

Also,

∠b=82°.

∠c=123°.

Check,

61°+82°+123°+42°+52°=360°.
