Answer:
See solution below
Step-by-step explanation:
The ball will hit the ground at whrn t = 0
Given the height of the ball modeled by the expression
h(t) = -16t^2 + 64
0 = -16t^2 + 64
16t^2 = 64
t^2 = 64/16
t^2 = 4
t = 2sec
The ball will hit the ground 2secs after
The domain are the values of the input values t and this values start from 2 and greater. Hence the domain of the function is {2, ∞}
when t = 2
h (2) = -16(2)^2 + 64
h(2) = -64+64
h(2) = 0
Hence the range are the output values i.e the height.
The range are within the range {0, ∞}

Answer:
20 gallons
Step-by-step explanation:
Divide 120 miles by 8 to find miles per gallon
120 ÷ 8 = 15 miles per gallon
Now divide 300 miles by 15 to find number of gallons required
300 ÷ 15 = 20
20 gallons are required for a journey of 300 miles
calculate the first four terms t=3n+2
Answer:
[tex]n = \frac{t - 2}{3} [/tex]
Step-by-step explanation:
1) Subtract 2 from both sides.
[tex]t - 2 = 3n[/tex]
2) Divide both sides by 3.
[tex] \frac{t - 2}{3} = n[/tex]
3) Switch sides.
[tex]n = \frac{t - 2}{3} [/tex]
Therefor, the answer is n = t-2/3.
solve for x in the triangle. round your answer to the nearest tenth
Answer:
x = 6.4
Step-by-step explanation:
Since you are given adjacent and hypotenuse use sin 53 = add/hyp
So .79863551 = x/8 so x = 6.3891
what is 3x- 12 = -2x - 42 ??? I know it equals -6 cause i did it on a caculator but how do i explain my answer ??
Answer
-6
Step-by-step explanation:
3x-12=-2x-42
(Collect like terms together:)
3x+2x=-42+12
(when the number crosses the equal sign it changes signs)
5x/5=-30/5
(We devided by 5 cause we looking for x not 5x)
Rewrite as a product of two factors: 3 + 18d + 21y
Answer:
[tex] \huge { \red{\boxed{ \boxed{ \tt \: 3(1 + 6d + 7y)}}}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:factoringlet's solve:in the following expression
everytime 3 is common
(3×1)+(3×6d)+(3×7d)
therefore if you take 3 from every expression we get
3(1+6d+7y)which is a product of two factors

A survey of teens showed that teens in Pittsburgh aged 12–17 spend 15.8 hours per week online. Teens in Miami/Ft. Lauderdale spends 14.2 hours per week online. Write and solve an additional equation to find the difference in time spent online by teens in these cities.
Answer:
1.6 hours
Step-by-step explanation:
Given that:
Time spent by Pittsburgh teens, p= 15. 8 hours
Time spent by Miami teens, m = 14.2 hours
The difference in time spent by the teens from these two cities is given by:
Time spent by Pittsburgh teens - Time spent by Miami teens
p - m
15.8 - 14.2 = 1.6 hours
rewrite the equation in slope-intercept form.
8x-4y=20

Find the interest earned from an investment of $14000 for 4 years at an interest rate of 6.85% compounded continuously. Round to the nearest cent.
Answer:
$4242
Step-by-step explanation:
Given data
Principal= $14000
TIme = 4 years
Rate= 6.85%
Let us find the final amount A
A=P(1+r)^t
substitute
A=14000(1+0.0685)^4
A=14000(1.0685)^4
A=14000*1.303
A=$18242
Hence the interest is
Interest= Final amount-Principal
=18242-14000
=$4242

to get the white flowers, add the two fraction and subtract them from 1
fraction of white flowers
Part- B
Fraction of flower red or Pink
[tex]\Rightarrow \dfrac{3}{8}+\dfrac{1}{3}=\dfrac{17}{24}[/tex]
Part-C
fraction of flowers that are white
[tex]\Rightarrow 1-\dfrac{3}{8}-\dfrac{1}{3}\\\\\Rightarrow 1-\dfrac{9+8}{24}\\\\\Rightarrow 1-\dfrac{17}{24}=\dfrac{7}{24}[/tex]
