Answer:
A) 5 x 0.89 and C) 5.31 x 10^0
Step-by-step explanation:
If you want two decimal places in the product, you have to multiply a number in the hundredths place and another number for a product in the hundredths. But the thing is, you have to make sure it doesn't end up in the tenth place such as 0.02 x 5 is 0.1.
So 5 x 0.89 is 4.45 and 5.31 x 10^0 is 5.31
We know that
[<span>percent of the races did Glenn crash]={[races crashed]/[total races]}*100
</span>[percent of the races did Glenn crash]={[9]/[30]}*100
[percent of the races did Glenn crash]=[0.30]*100=30%
the answer is 30%

The equation of the hyperbola with directrices at x = ±2 and foci at (5, 0) and (−5, 0) is
<h3>How to determine the equation of the hyperbola?</h3>
The given parameters are:
- Directrices at x = ±2
- Foci at (5, 0) and (−5, 0)
The foci of a hyperbola are represented as:
Foci = (k ± c, h)
The center is:
Center = (h,k)
And the directrix is:
Directrix, x = h ± a²/c
By comparison, we have:
k ± c = ±5
h = 0
h ± a²/c = ±2
Substitute h = 0 in h ± a²/c = ±2
0 ± a²/c = ±2
This gives
a²/c = 2
Multiply both sides by c
a² = 2c
k ± c = ±5 means that:
k ± c = 0 ± 5
By comparison, we have:
k = 0 and c = 5
Substitute c = 5 in a² = 2c
a² = 2 * 5
a² = 10
Next, we calculate b using:
b² = c² - a²
This gives
b² = 5² - 10
Evaluate
b² = 15
The hyperbola is represented as:
So, we have:
Evaluate
Hence, the equation of the hyperbola is
