What is true of the function g(x)=-2x^2+5?

Mathematics
1 answer:
mart [117]4 years ago
8 0

Answer:

C) The variable x represents the independent variable.

Step-by-step explanation:

The given function is g(x)=-2x^2+5.

g(x) is NOT the multiplication of g and x because g is a function of x.

x is the input of the function.

-2x^2+5 is the output of the function.

The variable x is called the independent variable because we plug in values of x to find g.

The variable g represents the output of the function NOT the input.

The correct choice is C

Ethan had $8 more than Dakota. Ethan then gave 1/4 of his money to Dakota. The ratio of money Ethan had to the money Dakota had
Paha777 [63]

Answer:

The amount with Dakota = $0.421

The amount with Ethan = $8.421

Step-by-step explanation:

Let the Initial amount with Dakota be 'x'

Therefore,

Amount with Ethan = x + $8

After giving \frac{1}{4} of money to the Dakota i.e \frac{1}{4} of ( x + $8)

Amount available with Dakota = x + [\frac{1}{4}\times(x+8)]

= \frac{5}{4}x+2

Amount available with Ethan = (x + $8) - [\frac{1}{4}\times(x+8)]

= \frac{3}{4}x+6

Now,

\frac{\frac{3}{4}x+6}{\frac{5}{4}x+2}=\frac{5}{2}

or

\frac{\frac{3x+24}{4}}{\frac{5x+8}{4}}=\frac{5}{2}

or

2(3x + 24) = 5(5x + 8)

or

6x + 48 = 25x + 40

or

25x - 6x = 48 - 40

or

19x = 8

or

x = $0.421

Hence,

The amount with Dakota = $0.421

The amount with Ethan = x + $8

= $0.421 + $8

= $8.421

Bus A and Bus B leave the bus depot at 8 am.
LenaWriter [7]

Answer: 10:55

Step-by-step explanation:

Taking statement at face value and the simplest scenario that commencing from 08:00am the buses take a route from depot that returns bus A to depot at 25min intervals while Bus B returns at 35min intervals.

The time the buses will be back at the depot simultaneously will be when:

N(a) * 25mins = N(b) * 35mins

Therefore, when N(b) * 35 is divisible by 25 where N(a) and N(b) are integers.

Multiples of 25 (Bus A) = 25, 50, 75, 100, 125, 150, 175, 200 etc

Multiples of 35 (Bus B) = 35, 70, 105, 140, 175, 210, 245 etc

This shows that after 7 circuits by BUS A and 5 circuits by Bus B, there will be an equal number which is 175 minutes.

So both buses are next at Depot together after 175minutes (2hr 55min) on the clock that is

at 08:00 + 2:55 = 10:55

Which of the following is not the same as 0.953 kilograms? 953,000mg 953g 9,530cg
balandron [24]
<span>10 mg = 1 cg 100 cg = 1 g 1000 g = 1 kg. Thus, 0.953 kg = 1000 x 0.953 = 953g 0.953 kg = 0.953 x 1000 x 100 = 95,300cg 0.953 kg = 0.953 x 1000 x 100 x 10 = 953,000 mg Therefore, from the give options, 9,530cg is not the same as 0.953 kilograms. Therefore, the correct answer to the question "Which of the following is not the same as 0.953 kilograms?"is 9,530cg</span>
