20 miles per hour converted to feet per second is 88/3 feet per second.
It is given in the question that there are 60 minutes in one hour and 60 seconds in one minute.
We have to convert 20 miles per hour in feet per second.
We know that,
1 mile = 5280 feet
1 hour = 60 minutes
1 minute = 60 seconds
Hence, we can write,
1 hour = 60*60 = 3600 seconds
1 mile per hour = 5280/3600 feet per second = 22/15 feet per second
Using unitary method, we can write,
20 miles per hour = 20*(22/15) = 88/3 feet per second or 29.3334 feet per second.

A retailer owes a wholesaler $300,000 due in 45 days. If the payment is 15 days late, there is a 1% penalty charge. Since the bill isn't due immediately, the retailer can invest the $300,000 in a certificate of deposit and make money on the interest. The retailer has two options: a 45-day certificate of deposit (CD) earning 6% per year simple interest or a 60-day certificate earning 7% per year simple interest.
A 45-day certificate of deposit (CD) earning 6% per year simple interest. Simple interest and precise simple interest are the two types of simple interest. $2250 is simple interest for the 6% interest.
What is simple interest ?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
Simple Interest is the amount repaid for using borrowed funds over a predetermined amount of time.
Simple interest=p*n*r
=300000*6/100*45/365
=2250
Ordinary simple interest and precise simple interest are the two types of simple interest. In order to calculate interest, a year is divided into 360 days for ordinary simple interest and 365 days (or 366 days for leap years) for exact simple interest.

The time taken for the bomb to fall to the ground is 2.5 sec.
What is a projectile motion?In this case, the bomb is moving like a projectile and has projectile motion.A body can only move in a projectile motion when it is affected by gravity. A body moving as a projectile is a projectile motion.We model a particle as having zero acceleration (and thus constant velocity) when it is projected horizontally.The particle in this instance has a zero initial velocity and a constant downward vertical acceleration of g.Given:
Height (h) = 50 m
Horizontal velocity(u) = 20 m/s
Time (t) =?
We use, h = ut to determine the time
50 = 20 × t
Divide both sides by 20,
t = 50 / 20
t = 5/2 s ≅ 2.5 sec
Thus, the bomb will take 2.5 sec to land on the ground.

the graph of g(x) = (x + 2)2 is a translation of the graph of f(x) ___ by ___ units
The provided translated function, f(x), shifts left by two units on the horizontal axis.
Describe translation.One type of transformation is translation. Both the scaling calculation and the compression calculation are performed using it. This approach wouldn't change the object's form or shape.
The given graph equation for the translation, as per the query, is g(x) = (x + 2)²
The translation of the given quadratic function is: y = g(x) = (x + 2)²
Consequently, the parent function is written as y = g(x) = x2.
Additionally, the vertex should be known when graphing the translated function:
a(x - h)2 + k = y = g(x);
where the parent function is (0, 0) and the vertex values are (h, k).
(h, k) = is the vertex for the function that is provided (-2, 0)
This information causes the translation function to move the graph two units to the left.
Horizontal translation is the name given to the translation.
As a result, the given function, f(x), shifts horizontally, or left, by 2 units.

Answer:
x = 8
y = 8
Step-by-step explanation:
The two equations are:
x + y = 16 (1)
x = y (2)
Since x = y substitute for y in terms of x in (1):
x + x = 16
2x = 16
2x/2 = 16/2
x = 8
y = 8
The numerator of a rational number is 4 less than its denominator. If I is added to both its numerator and denominator, it becomes 2/3 Find the rational number.
The required rational number is 7/11.
let the denominator be x.
and since we are given that the numerator of a rational number is 4 less than its denominator, the numerator will be x-4.
working on the given condition, i.e. If I is added to both its numerator and denominator, it becomes 2/3
(x-4+1)/(x+1) = 2/3
further solving it by cross multiplication we get,
3(x-4+1)=2(x+1)
=> 3(x-3)=2x+2
=> 3x-9=2x+2
=> 3x-2x=9+2
=> x=11
=> x= 11 (denominator)
we know the numerator is 4 less than the denominator i.e.
11-4=7
thus the required fraction will be 7/11.

Write an equation for the quadratic graphed below:
x-intercepts: (-3,0) and (-1,0); y-intercept: (0,-2)
The equation for the quadratic graphed as x-intercepts: (-3,0) and (-1,0); y-intercept: (0,-2) can be written as y = -1/2 (x+3)(x+1)
Which of these equations is quadratic?An equation of the second degree, or one with at least one squared term, is a quadratic equation. The equation in standard form is written as ax2 + bx + c = 0, where a, b, and c are numerical coefficients that are constants, and x is an unknown variable.
The initial constant, “a,” cannot be 0, and this is an unbreakable rule.
How do you translate a graph into some equation?In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The slope is the ratio of the y-to-x change.
Thereafter draw a sloping triangle connecting the two spots you find on the line.
If the x intercepts are -3 and -1, then the factored form is y = a(x + 3)(x + 1). In order to find "a", we plug in the data point (x, y) of (0, -2) so:
-2 = a(0+3)(0+1)
-2 = 4a
a = -1/2
So the equation can be written as y = -1/2 (x+3)(x+1)
