Answers

Answer 1
-10c
hope this helped !!!
Answer 2

Answer:

-10c

Step-by-step explanation:

-4(c+2d)-2(3c-4d) = (-4c-8d) + (-6c+8d)

Multiply (-4) to both terms in the first bracket and multiply (-2) to both terms in the second bracket.

(-4c-8d) + (-6c+8d) = -4c-8d-6c+8d

Evaluate like terms.

-4c-8d-6c+8d = -10c

Domain[-2, ∞)
Range(-∞, ∞)

Answer:

The domain is x ≥ − 2 and the range is AllRealNumbers

Step-by-step explanation:

Alrighty, first of all, the domain is the number or amount of x coordinates in the function. The range is the number or amount of y coordinates in the function. As we can see, the x coordinates stretch out towards the right starting from -2. We can include -2, so the domain would be x ≥ − 2.  The range would be AllRealNumbers because it streches out infinitely both upwards and downwards.

Danny charges $44 for 4 hours of swimming lessons, Martin charges $42 for 3 hours of swimming lessons. Who offers a better deal?

Answers

Danny, he charges $11 per hour, while Martin charges $14 per hour.

Answer:

I would say that Danny's deal is better.

Step-by-step explanation

If you wan t to know the better deal you should first figure out how much they charge per hour. All you have to do is divide the price by the amount of hours.

Danny: 44 ÷ 4 = 11

Martin: 42 ÷ 3 = 14    

Martin charges more money for fewer hours. Danny charges less for 4 whole hours, so he would be the better deal!!!

Answers

2(3+3) or 2(3)+6, so the answer is the third option. It’s just using the distributive property.

Answer:

2(3)+6

Step-by-step explanation:

a = 3

substitute a with 3

2(a+3)

= 2(3+3)

= 2(6)

i) 2(3) = 6 ❌

ii) 5(3) = 15 ❌

At right is the tunnel entrance that runs through
Castle Hill in Budapest, Hungary.



-a If the maximum height of the tunnel is the
same as its maximum width, 9.8 meters,
determine a quadratic model to represent
the tunnel
-b State a geometric model that could be used to
represent a truck passing through the tunnel.
-c If a typical truck has a width of 2.62 m,
determine the height limitation that should
be put on these trucks if they are going to
travel through the tunnel safely. State any
assumptions that you made and be sure to
show all of the steps in your solution.
-d Because its length is almost 350 meters,
a truck stopped in the tunnel would need
enough room for the passenger door to open
fully. Suppose a truck with a width of 2.6 m
and height of 3.4 m is stuck in the right lane
of the tunnel by the center line. The top of
the driver's door is 0.2 m below the top of the
truck, and the door opens 0.8 m to the side.
Show that the door can open fully, showing
all of your steps.
-e Determine how close to the side of the tunnel
the truck could be in d be and still be able to
open the passenger door.
-f Describe some issues/concerns that you
think architects take into account when
modelling a tunnel before its construction

Answer:

My buddy what's popping??

Step-by-step explanation:

Those coming from the Pest end had to walk round the Castle Hill on the Buda side to be able to proceed northwards. On 10 February 1853, four years after the completion of the Chain Bridge, the building of a tunnel leading through the hill was started to the plans of Adam Clark. On 6 March 1856, the tunnel was opened for foot traffic, and on 30 April 1857 also for motor traffic. Being 350 meters in length, it leads through under the Buda Castle to the other side of the hill. Its length is approximately identical to that of the Chain Bridge, prompting anecdotes according to which the tunnel has only been built so that in rainy weather, the Chain Bridge can be shoved in and be protected from wet conditions. The entry of the tunnel at its Chain Bridge end was also fittingly designed in classicist style.

In a company's first year in operation, it made an annual profit of $277,000. The
profit of the company increased at a constant 18% per year each year. How much
total profit would the company make over the course of its first 5 years of operation,
to the nearest whole number?

Answers

633,708 is the answer I got

Over the course of its first 5 years of operation, total profit the company would make is $633,709 .

What is a compound interest?

"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."

Given, the annual profit of the company at first year = P =$277,000.

The rate of increase of profit = r% = 18% =0.18.

Total duration = n = 5.

Therefore, after first 5 years of operation, total profit the company would make = P[(1 + r)/100]ⁿ

= $277,000(1 + 0.18)⁵

=$633,708.9

≈$633,709

After 5 years , the total profit would have $633,709.

Use slope formula: m = (y2 - y1)/(x2 - x1)

m = (-5 - (-6))/(1 - (-1)) = 0.5

The line in slope-intercept form is (y = mx + b)

y = 0.5x - 5.5

Will is buying a house for $185,000. He is financing $165,000 and obtained a 30-year, fixed-rate mortgage with a 6.725% interest rate. How much are his monthly payments? (2 points)

Answers

Answer:  $1067.45

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

Work Shown:

L = 165000 = loan amount or amount financed

r = 0.06725  = annual interest rate in decimal form

i = r/12 = 0.06725/12 = 0.005604167

i = 0.005604167 = approximate monthly interest rate in decimal form

n = number of months = 30*12 = 360 months

P = unknown monthly payment

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

Apply the monthly payment formula

P = (L*i)/( 1-(1+i)^(-n) )

P = (165000*0.005604167)/(1-(1+0.005604167)^(-360))

P = 1067.44636311118

P = 1067.45

What is the slope of the line that passes through the points (-4, -2)and (−4,−22)? Write your answer in simplest form.

Answers

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

From the question we have

[tex]m = \frac{ - 22 - - 2}{ - 4 - - 4} = \frac{ - 22 + 2}{ - 4 + 4} = - \frac{20}{0} \\ [/tex]

Any number divided by zero is undefined so the slope of the line is undefined.

Hope this helps you

Answer:

Undefined ([tex]\infty [/tex])

Step-by-step Explanation:

We need to find the slope of the line joining the points (-4, -2) and (-4, -22).

We know that, Slope is the difference of abcsissa (x - coordinate) / difference of ordinates (y-coordinate)

[tex]m = \dfrac{y2 - y1}{x2 - x1} [/tex]

Here:

x1 = -4x2 = -4y1 = -2y2 = -22

Plugging these values:

[tex]m = \dfrac{ - 22 - ( - 2)}{ - 4 - ( - 4)} [/tex]

This can be written as:

[tex]m = \dfrac{ - 22 + 2}{ - 4 + 4} [/tex]

[tex]m = \dfrac{ - 20}{0} = \infty [/tex]

Here, The slope of the line is infinite or undefined. An undefined slope (or an infinitely large slope) is the slope of a vertical line!
