The answer the 3,
First you have to apply the exponent rule which is 1 - 3• 1/g
Then you multiply the fractions - 1•3/g
Then multiply the numbers 1 and 3, which is 3, so there you have it 3/g, or 3, they’re the same thing.
Answer:
Step-by-step explanation:
<h3>Question-1:</h3>
so when <u>flash down</u><u> </u>occurs the rocket will be in the ground in other words the elevation(height) from ground level will be 0 therefore,
to figure out the time of flash down we can set h(t) to 0 by doing so we obtain:
to solve the equation can consider the quadratic formula given by
so let our a,b and c be -4.9,229 and 346 Thus substitute:
remove parentheses:
simplify square:
simplify multiplication:
simplify Substraction:
by simplifying we acquire:
since time can't be negative
hence,
at <u>4</u><u>8</u><u>.</u><u>2</u><u> </u>seconds splashdown occurs
<h3>Question-2:</h3>
to figure out the maximum height we have to figure out the maximum Time first in that case the following formula can be considered
let a and b be -4.9 and 229 respectively thus substitute:
simplify which yields:
now plug in the maximum t to the function:
simplify:
hence,
about <u>3</u><u>0</u><u>2</u><u>1</u><u>.</u><u>6</u><u> </u>meters high above sea-level the rocket gets at its peak?
Answer:
x = 21°
Step-by-step explanation:
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
x = 21°
Answer:
2 cups per teaspoon, 2 cups/1 tsp
Step-by-step explanation:
to get the teaspoon amount to 1 (you have to for a unit rate), you multiply both sides by 4.
1/2 x 4 = 2
1/4 x 4 = 1
162 short sleeve shirts; if you add 9 and 4, you get 13. Then, divide 234 by 13, which equals 18. 18 multiplied by 9 is 162.
