Answer:
As we can see in the picture, we already knew 4 out of 6 sides of the figure so we need to find the other sides.
So the first missing side (the one near the 3 m one) should be:
7 - 4 = 3 (m)
The second missing side (the one near the 4m one) should be:
6 - 3 = 3 (m)
Now that we know all of the side lengths of the figure, the perimeter of the figure will be:
7 + 3 + 3 + 3 + 4 + 6 = 26 (m)
Answer:
The area of a rectangle is length*width
Step-by-step explanation:
The answer is A
This is simple
The length of the diameter = sqrt ( (7-1)^2 + (5 - -3)^2)
= sqrt 100 = 10 units so the radius = 1/2 * 10 = 5 units
so the right side of the equation = 5^2 = 25
Centre of circle = midpoint of the diameter = (-3+5)/2 , (1 + 7)/2 = (1 , 4)
so the correct equation is (x - 1)^2 + (y - 4)^2 = 25
Answer:
Step-by-step explanation:
Let's check for linear first. We will do that by usingseveral of the points in the slope formula and seeing if the slope between the points is the same each time. Using (0, 1) and (1, 3):
then using the next 2 sets of coordinates (1, 3) and (2, 9):
So obviously this is not linear since the slope values are different. Let's try exponential first. We will use the first 2 coordinates to write the model and then test it out on another point. Use (0, 1) and (1, 3) in
so
and
a = 1. Using that a value along with the next coordinate we will write a model:
so
b = 3. The model then is
Let's test it out. Sub in a 2 for x and see if we do in fact that y = 9:
and
y = 9
This is exponential. You can try the next coordinate if you'd like, but since 3 cubed = 27, you know it works. Choice B Exponential
The first step is to find how many gallons of gas you can purchase:
3.90 divided by 32 = about 12
So, you can buy gas 12 times.
Next, how many litres is in that?
One gallon is 3.785 litres so the formula would be to multiply the value of gallons by 3.785
in this case, it’s:
12 x 3.785 = 45.42
Now that we know how many litres you can buy, we simply have to mind how much we can drive with that amount of gas. If you can drive 14 km with one litre, we simply have to multiply the amount of litres of gas we have by 14.
(14 x 45.42 = 635.88 )
Therefore, you can drive 634.88km with $3.90.
