The expression for the distance the car travels after t seconds is d = 200t + 50t²
<h3>Equation of motion </h3>
From the question, we are to write an expression for the distance the car travels after t seconds
From the given information,
The equation for the motion of an object with constant acceleration is
d = vt + 0.5at²
For the race car,
v = 200 ft/s
a = 100 ft/s²
Putting the parameters into the equation, we get
d = 200t + 0.5(100)t²
d = 200t + 0.5 ×100)t²
d = 200t + 50t²
Hence, the expression for the distance the car travels after t seconds is d = 200t + 50t²

#SPJ1
The answer is D
3*-42=-126
The factors of -126 that add to -11 are 7 and -18
replace -11h with 7h-18h
3h^2 + 7h - 18h - 42
Factor the first two terms and last two terms
h(3h+7) - 6(3h+7)
See how the two parentheses are the same?
THE ANSWER IS BELOW!!
(h-6)(3h+7)
the first parentheses has the terms that were outside, and the second has the original bracketed terms
This matches option D (it just multiplies the terms backwards, which gives the same result)
Answer:
At the given rate it will take 3 years and 5 months for the investment to be doubled
Step-by-step explanation:
Here, we want to get the amount of time it will take an investment that earns 12.25% to double if it’s compounded continuously
We can have the exponential relation as follows;
P = I( 1 + r)^n
P is the present value, let us call this 2x as it two times the initial
I is the initial value which is x in this case
r is the interest rate = 12.25% which is same as 12.25/100 = 0.1225
n is the number of years which we want to calculate
Thus, we have
2x = x( 1 + 0.1225)^n
2 = 1.225^n
Ln 2 = n ln 1.225
n = ln 2/ln 1.225
n = 3.42
if 3.42 is the number of years, let us have 0.42 in months
That will be 0.42 * 12 = 5.04
So we are looking at the investment being doubled at 3 years and 5 months
<span>Frieda's weight is 1 Standard Deviation above the meanwhile her height is less than 1 Standard Deviation away from the mean. This means her height is closer to the mean than her weight.
As a result, we would say that her weight is definitely more unusual than her height because her weight is more standard deviations away from the mean.
Therefore,
</span><span>in relative terms, it is correct to say that:</span> Frieda's height is more unusual than her weight.
