A car is traveling at a rate of 35 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 5 hours?
round your answers.

Answers

Answer:

120km/h

600km in 5 hours.

Step-by-step explanation:

1000 meters is equal to 1 kilometer. 1 meter is equal to .001 kilometer.

You can set up an equation like this to solve for the car's rate in kilometers.

[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}[/tex]  or  [tex]\frac{1000 m}{1000 km} = \frac{x m}{35km}[/tex].

Now crossmultiply either fraction to solve for x.

[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}\\\frac{1 km}{1000 m}*35 = \frac{x km}{35m}*35\\\frac{35 km}{1000 m} = xkm[/tex]

The car is going at .035km/sec. Now we need to multiply this to get kilometers per hour. There are 60 seconds in a minute and there are 60 minutes in a hour.

[tex]\frac{35}{1000} * 60 * 60[/tex]

The car travels at 120km per hour.

Since we now know the rate in kilometers per hour. We can multiply the rate by 5 since the question asks how many kilometers the car will travel in 5 hours.

120 * 5 = 600

The car will travel 600km in 5 hours.

The length of a rectangle is 3 ft less than twice the width, and the area of the rectangle is 44 ft squared. find the dimensions of the rectangle

Answers

The dimensions of the rectangle are 4 ft by 5 ft.

Given that the length of a rectangle is 3 ft less than twice the width, and the area of the rectangle is 44 sq.ft. We have to find the dimensions of the rectangle. Let's consider the width of the rectangle as x ft.Length of the rectangle = (2x - 3) ftArea of the rectangle = Length x Width44 = (2x - 3) x x44 = 2x^2 - 3x44 = x (2x - 3)2x^2 - 3x - 44 = 0To solve for x, we will factorize the equation by splitting the middle term.2x^2 - 8x + 5x - 20 = 0Factorize2x(x - 4) + 5(x - 4) = 0(x - 4) (2x + 5) = 0x = 4 ft (since the width of a rectangle can't be negative)or 2x = -5This gives us an invalid value, so x = 4 ftNow that we have the width of the rectangle, we can calculate the length as follows:Length of the rectangle = (2x - 3) ftLength of the rectangle = (2 * 4) - 3Length of the rectangle = 8 - 3Length of the rectangle = 5 ft.

Find a so that the point (-1,5) is on the graph of f(x)=ax2+1

Answers

Step-by-step explanation:

to solve for a,

f(-1) = 5

a(-1)^2 + 1 = 5

a + 1 = 5, so a=4

The required value is [tex]a=4[/tex]

The given point is (-1,5)

And the graph is [tex]f(x)=ax^2+1[/tex]

Now, substituting the point into the given equation we get,

[tex]f(-1)=a(-1)^2+1=5\\a+1=5\\a=5-1\\a=4[/tex]

So, the required value is [tex]a=4[/tex].
