If three times the larger of two numbers is four times the smaller and the difference between the numbers is 8, then the larger of the two numbers is:
Answer:
Larger number = 32
Step-by-step explanation:
Smaller number = x
Larger number = y
y - x = 8 -----------(I)
3y = 4x ---------------(II)
3y/4 = x
Plug in x = 3y/4 in equation (I)
[tex]y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\[/tex]
y = 8*4
y = 32
Plug in y = 32 in equation (II)
3y = 4x
3*32 = 4x
4x = 3*32
x = [tex]\frac{3*32}{4}[/tex]
x = 3 *8
x = 24

Caitlin is designing a railing for a set of stairs. The railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 inches for every 12 horizontal inches.
A drawing of the side view of a set of 4 stairs. There are lines drawn to show a railing that is at the highest point of the stairs and labeled 36 inches.
Which function can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs?
y = –StartFraction 3 Over 4 EndFractionx + 36
y = –3x + 36
y = StartFraction 3 Over 4 EndFractionx + 36
y = 3x + 36

3x2+5y for x = 4 and y = 2.
Need a right answer ASAP
Answer:
It depends of what the equation is...
Step-by-step explanation:
If your equation is 3x2 (3x times 2) then the solution would be:
3(4)(2) + 5(2)= 34
If your equation is 3x + 2 + 5y, then the solution would be:
3(4) + 2 + 5(2) =24

Answer:
13. [tex]D = 18[/tex]
14. [tex]S = (x, y + 6)[/tex]
Step-by-step explanation:
13.
Given
[tex]M = (-8,2)[/tex]
[tex]S = (10,2)[/tex]
Required
Determine the distance between M and S
Distance (D) is calculated using:
[tex]D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]
Where
[tex](x_1,y_1) = (-8,2)[/tex]
[tex](x_2,y_2) = (10,2)[/tex]
[tex]D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]
[tex]D = \sqrt{(10 - (-8))^2 + (2 - 2)^2}[/tex]
[tex]D = \sqrt{(10 +8)^2 + 0^2}[/tex]
[tex]D = \sqrt{18^2 + 0}[/tex]
[tex]D = \sqrt{18^2}[/tex]
[tex]D = 18[/tex]
Hence, the distance between M and S is 18 units
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.
[tex]P=(x,y)[/tex]
Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is
[tex]S = (x, y + 6)[/tex]
i.e. we add the units to the y coordinate of P.

The function h(t) = -16t2 + 48t + 28 models the height (in feet) of a ball where t is the time (in seconds).
What is the maximum height that the ball reaches? Just write the numerical answer - do not include h = or any units in your
answer.
Answer:
64
Step-by-step explanation:
[using calculus] When the function h(t) reaches its maximum value, its first derivative will be equal to zero (the first derivative represents velocity of the ball, which is instantaneously zero). We have [tex]h'(t) = -32t + 48[/tex], which equals zero when [tex]t = 3/2 = 1.5[/tex]. The ball therefore reaches its maximum height when t = 1.5. To find the maximum height, we need to find h(1.5), which is 64 feet.
[without calculus] This is a quadratic function, so its maximum value will occur at its vertex. The formula for the x-coordinate of the vertex is -b/2a, so the maximum value occurs when t = -48/(2*16), which is 1.5. The maximum height is h(1.5), which is 64 feet.
The cordinate of point A on a grid are (-3,-2). Point A is reflected across the y-axis to obtain part B. The coordinates of point B are (__,-2)
Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.
A(-3, -2) => B(3, -2).

The probability is 1 in 4,011,000 that a single auto trip in the United States will result in a fatality. Over a lifetime, an average U.S. driver takes 46,000 trips.(a) What is the probability of a
Answer:
0.0114
Step-by-step explanation:
(a) What is the probability of a fatal accident over a lifetime?
Suppose A be the event of a fatal accident occurring in a single trip.
Given that:
P(1 single auto trip in the United States result in a fatality) = P(A)
Then;
P(A) = 1/4011000
P(A) = 2.493 × 10⁻⁷
Now;
P(1 single auto trip in the United States NOT resulting in a fatality) is:
P([tex]\mathbf{\overline A}[/tex]) = 1 - P(A)
P([tex]\mathbf{\overline A}[/tex]) = 1 - 2.493 × 10⁻⁷
P([tex]\mathbf{\overline A}[/tex]) = 0.9999997507
However, P(fatal accident over a lifetime) = P(at least 1 fatal accident in lifetime i.e. 46000 trips)
= 1 - P(NO fatal accidents in 46000 trips)
Similarly,
P(No fatal accidents over a lifetime) = P(No fatal accident in the 46000 trips) = P(No fatality on the 1st trip and No fatality on the 2nd trip ... and no fatality on the 45999 trip and no fatality on the 46000 trip)
= [tex][P(\overline A)] ^{46000} \ \ \ (since \ trips \ are \ independent \ events)[/tex]
= [tex][0.9999997507]^{46000}[/tex]
= 0.9885977032
Finally;
P(fatal accident over a lifetime) = 1 - 0.9885977032
P(fatal accident over a lifetime) = 0.0114022968
P(fatal accident over a lifetime) ≅ 0.0114

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 12(1.03)n
Part A: When the scientist concluded his study, the height of the plant was approximately 16.13 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(n) represent? (2 points)
Part C: What is the average rate of change of the function f(n) from n = 3 to n = 10, and what does it represent? (4 points)
9514 1404 393
Answer:
A) domain: 0 ≤ n ≤ 10
B) the height at the start of the study
C) 0.431 cm per day, average growth rate
Step-by-step explanation:
A) The study started on day 0 and ended on day 10. A reasonable domain is ...
0 ≤ n ≤ 10
__
B) The y-intercept of the graph of plant height is the height of the plant on day 0, the day the study started.
__
C) On day 3, the height was ...
f(3) = 12·1.03^3 ≈ 13.1127 . . . cm
On day 10, it was ...
f(10) = 12·1.03^10 ≈ 16.1270 . . . cm
Then the plant grew at an average rate of ...
(16.1270 -13.1127) cm/(10 -3 days) ≈ 0.431 . . . cm/day
The average rate of change is the average rate of growth of the plant in the given period.
The perimeter of a triangle is 70 in. The shortest side is 11 in. less than the longest side. The middle side is 24 in. less than the combined lengths of the
shortest and longest sides. Find the lengths of the three sides.
Answer:
The sides are
6
inches,
8
inches and
10
inches
Explanation:
I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'
In this case the question can be answered. If
x
is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4
x+3/4x+3/4x+4=24
10/4x=20
x=8
Then the shortest side is 6and the longest side is 10
