Tyler wants to buy a new tub and that cost $312. He has already saved the plan to save $24 per week over the next few weeks whic
laila [671]

Answer:

13 weeks

Step-by-step explanation:

Given that :

Cost of new tub = $312

Planned saving per week = $24

The number of weeks he'll have to save in other to be able to afford the tub can be obtained using the relation :

Number of weeks = cost of new tub / weekly saving

Number of weeks = $312 / $24

Number of weeks = 13 weeks

a taxi ride costs 40 dollars for the first 500 meters and each additional 300 meters (or a fraction thereof) adds $3.50 to the f
Colt1911 [192]

Answer:

$ 71.5

Step-by-step explanation:

firstly kilometer to meters

<em>1 km = 1000 m </em>

therefore 3 km = 3000m

for the first 500 = $40

hence deduct the 500 from 3000m

3000 - 500 = 2500

now find out how many 300m go into 2500

2500 / 300 = 8.33

which is rounded up to 9

therefore the total amount is :

40 + 9 * 3.5

<u>= $71.5</u>

What is the circumference of a circular disc with a diameter of 10 centimeters? (Round your answer to the nearest tenth.)
Evgen [1.6K]
To determine what the circumference is simply take the value of the diameter and multiply it to the value of Pi or 3.141....

C = Pi • d
C = (3.14)(10 cm)
C = 31.41 cm or 31.4 cm, rounded to the nearest tenth.

How does changing the number outside the parentheses of an exponential function change your graph? y = a(b)^x
Zarrin [17]

Answer:

See Below.

Step-by-step explanation:

We have the function:

y=a(b)^x

Depending on the behavior of the coefficient, many things can happen. The parent exponential function has a=1. If a is something other than 1, however, there are three main changes.

Let’s use b=2 to illustrated the examples.

(In the graphed examples, below, the parent function (with b=2) is the red curve.)

  • If <em>a</em> is a positive, rational number greater than 1.

If a is a positive number other than 1, say 2, then this represents a vertical stretch.

In other words, our function is stretched closer to the y-axis.

(This is the blue curve. It is closer to the y-axis than the parent function (red curve).)

  • If <em>a</em> is a positive, rational number greater than 0 but less than 1.

If a is a number between 0 and 1 (so a fraction), say, 1/2, then this represents vertical compression.

In other words, our function gets farther away from the y-axis.

(This is the black curve.)

  • If <em>a </em>is a negative.

If a is <em>negative</em>, then this means that the graph was flipped over the x-axis.

(This is the green curve.)

Note that if we have something such as a=-2 or a=-1/2, this means that the function we flipped over the x-axis first and <em>then</em> vertically stretched or compressed.

(And example of this is illustrated with the orange curve).
