Answer:
an = 4/3n - 13/3.
Step-by-step explanation:
The first term is a1,
a24 = a1 + 23d
83/3 = a1 + 4/3* 23
a1 = 83/3 - 92/3
a1 = -9/3 = -3.
So the nth term an = -3 + 4/3(n - 1)
an = -3 + 4/3 n - 4/3
an = 4/3n - 13/3
Answer: Ok first if you read the directions read them again, then you look at the problem carefully and make an equation that should look close to this: 0.75xp=c, Once you have that equation you have to replace the p with a 2 and multiply to get an answer of 1.50. The second part would be taking 0.5x2 which is easy it would be 0.10 then you take that and minus it from the total of the last problem which would get you to $1.40
Step-by-step explanation:
If Terrence is skating at a constant rate then the answer to b would be it is a function. On a You say how close he is to the motion detector in feet during the second he says. Since the seconds is on the first one 0 then he is 0 feet. Then 2, 4, 6, 8. Because every second he gets to feet colser. On c, the independent variable is how time, and the dependent variable is distance from motion detector. The independent variable is what you change and the dependent variable changes because of the independent variable. Hope this helped!
Answer:
38
Step-by-step explanation:
Since 19 is 50% of x, we multiply it by two
19 x 2 = 38

Okay, so two of the sides in an isosceles triangle are of the same length. The lengths are either in the ratio 5:5:6 or 5:6:6
The perimeter is 32 cm
If we take the first ratio, 5:5:6, then we have 16 "parts". Let the length of each "part" be referred to as "x"
So, 16x = 32, and so x = 2
So, the ratio of the sides are 10 cm, 10 cm, 12 cm.
To find the height, "h", we need to use Pythagoras' Theorem, with 10 being the hypotenuse and 6 being the horizontal side (think of a line cutting straight down the middle of the isosceles triangle)
h^2 + 36 = 100
h = 8 cm
Area of a triangle is 0.5 x base x height. So, 0.5 x 12 x 8 = 48 cm^2
Hope I helped!! xx
