Answer:
Step-by-step explanation:
6¼ ft - 8¾ ft = -2½ ft
(-2½ ft)/(1⅔ min) = (5/2 ft)/(5/3 min)
= (5/2)/(5/3) ft/min
= (5/2 × 3/5 ft)/min
= 1.5 ft /min
The required change in elevation of butterfly is 1.5 ft\min.
Given that,
A butterfly is flying [tex]8\frac{3}{4}[/tex] feet above the ground.
It descends at a steady rate to a spot [tex]6 \frac{1}{4}[/tex] feet above the ground in [tex]1\dfrac{2}{3}[/tex] minutes.
We have to determine,
The butterfly’s change in elevation each minute.
According to the question,
Change in elevation = butterfly flying above ground - it descends at a steady rate to a spot above the ground ,
[tex]= 8\dfrac{3}{4} - 6\dfrac{1}{4}\\\\= \dfrac{35}{4} - \dfrac{25}{4}\\\\= \dfrac{10}{4}\\\\= \dfrac{5}{2}\\\\= 2.5 feet[/tex]
Then,
To find Change in elevation per minute,
[tex]= T = 1\dfrac{2}{3} = \dfrac{5}3}[/tex]
Therefore,
Change in elevation per minute,
[tex]= \dfrac{2.5}{\frac{5}{3}} = 2.5 \times \dfrac{3}{5} = 1.5 \ ft \ per\ minute[/tex]
Hence, The required change in elevation of butterfly is 1.5 ft\min.

What are the zeroes of f(x) = x2 + 5x + 6?
Answer:
The zeroes are: -3 and -2
Step-by-step explanation:
f(x) = x² + 5x + 6
This is the in the format...
ax² + bx + c
To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.
The two numbers are...
3 + 2 = 5 (This is correct because the two numbers add are equal to B)
3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)
You then know that you have ( x + 3 ) and ( x + 2 )
Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.
Here's what I mean by that...
x + 3 = 0
Subtract 3 on both sides...
x = -3
The other zero...
x + 2 = 0
Subtract 2 on both sides...
x = -2
Your answers are x = -2 and x = -3, make sure you always set your answers to zero.

Ophelia read ⅕ of her 60 pages book in ½ hour. How many pages can she read in one hour?
Answer:
She can read 24 pages in one hour.
Step-by-step explanation:
[tex]\frac{1}{5}*2[/tex] = [tex]\frac{2}{5}*60pages = 24pages[/tex]
hope this helps, good luck :)
Step-by-step explanation:
1/5 * 60 = 12 pages read in 1/2 hour
there are 2 half hours in an hour
so
12*2 = 24 pages in one hour.
Kiera and Hannah have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Kiera earns a base wage of $6 per hour, as well as $1 for every subscription that she sells. Hannah gets $2 per subscription sold, in addition to a base wage of $4 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How many subscriptions would that be? Write a system of equations, graph them, and type the solution
Answer:
Hannah sold 4
Kiera sold 6
Total Subscriptions = 10
Step-by-step explanation:
K = number of Kiera subscriptions
H = number of Hannah subscriptions
T = hours
6+K = 4+2H
K = 2H-2
K+H = 10
K= 10-H
substitute for K
2H-2 = 10-H
simplify
3H = 12
H = 4
K = 6

Suppose that 20% of students at high school A and 18% of students at high school B participate on a school athletic team. Independent random samples of 30 students from each school are selected and asked if they participate on a school athletic team. Let ˆ p A represent the sample proportion of students at school A who participate on a school athletic team and ˆ p B represent the sample proportion of students at school B who participate on a school athletic team.
What is the value of n A p A ?
What is the value of n A ( 1 − p A ) ?
What is the value of n B p B ?
What is the value of n B ( 1 − p B ) ?
Is the shape of the sampling distribution approximately Normal?
____, these values _____ all at least 10.
Answer:
6 ; 24 ; 5.4 ; 24.6
Step-by-step explanation:
Given that:
Number of samples from each high school = 30
Proportion of students from high school A = 20%
Proportion of students from high school B = 18%
Number of sample A ; n(A) = 30
Proportion of sample A ; p(A) = 0.20
Number of sample B ; n(B) = 30
Proportion of sample B ; p(B) = 0.18
1.)
n(A).p(A) = 30 * 0.20 = 6
2.)
n(A). (1 - p(A))
30 * (1 - 0.20)
30 * 0.8 = 24
3.)
n(B).p(B) = 30 * 0.18 = 5.4
4.)
n(B). (1 - p(B))
30 * (1 - 0.18)
30 * 0.82
= 24.6
Shape of sampling distribution is not approximately normal ;
Both nApA and nBpB are < 10

What feature or features of the parabolic parent function f(x)=x^2 would change if f(x) was replaced with 2f(x-4)? Help please:)
Answer:
The y-intercept of the function and the vertex of the function would change. (III and IV) This answer doesn't seem to be in the answer list (but there is proof for the answers below), though.
Step-by-step explanation:
(Notice that [tex]2f(x-4) = 2(x-4)^2.[/tex])
The domain of the function won't change because quadratics can all take all numbers as their input (which, by definition, is the domain of a function).
The range of the function won't change either, because we have just moved the function with 4 to the right (by substituting [tex]x[/tex] with [tex]x-4[/tex]) and multiplied the graph with respect to the y-axis by 2. The range will stay as all non-negative real numbers.
The y-intercept of the function will change, because for [tex]f(x)=x^2[/tex] it is [tex]y=0[/tex], while for [tex]y=2(x-4)^2[/tex] substituting [tex]x=0[/tex] doesn't give [tex]y=0[/tex]. (Instead, it gives [tex]y=32[/tex].)
The vertex of the function will change, because we have moved the function with 4 to the right and multiplied the graph with respect to the y-axis by 2: the vertex will have at the very least moved to the right.

F(x)=4x^2+4x-15 Write the function D in intercept form. Use this form to list the zeros of the function.
Answer:
Zeros are x = 1.5, -2.5
Step-by-step explanation:
Given function is,
F(x) = 4x² + 4x - 15
= 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]
F(x) = 4(x² + 2.5x - 1.5x - 3.75)
= 4[x(x + 2.5) - 1.5(x + 2.5)]
= 4(x - 1.5)(x + 2.5)
For 'x' intercepts,
f(x) = 0
4(x - 1.5)(x + 2.5) = 0
x = 1.5, -2.5
Therefore, zeros of the given function are x = 1.5, -2.5.
