Answer:
Option 2: 14.06 minutes
Step-by-step explanation:
For the first scenario, we will convert the minutes into hours first to get all the quantities in same unit
So,
15 minutes = 1/4 hours = 0.25 hours
Speed = 7.5 miles per hour
Now using the speed, distance and time formula
Speed = distance/time
[tex]Speed = \frac{distance}{time}[/tex]
[tex]7.5 = \frac{distance}{0.25}[/tex]
[tex]7.5 * 0.25 = Distance[/tex]
Distance = 1.875 miles
So the distance for 1st day is 1.875 miles.
For next day
Speed = 8 miles per hour
Distance = 1.875
So,
[tex]speed = \frac{distance}{time}[/tex]
[tex]8 = \frac{1.875}{time}[/tex]
[tex]time = \frac{1.875}{8}[/tex]
[tex]time = 0.234375 hours[/tex]
Converting the hours into minutes will give
0.234375 * 60 min = 14.0625 minutes
Rounding off to two decimals = 14.06 min
So 2nd option is correct..

which is the graph of the linear equation y = - 1/3x + 5
Answer:
The second one.
Step-by-step explanation:
The slope of the graph, -1/3, is going down from left to right because it is negative, so it is decreasing. Slope is the rise over run, so because the slope is -1/3 look for lines that go down 1 unit and across 3 at the same time (from one corner of a square to the other). Then, because your y-intercept is a 5, just look for your line to cross the y-axis at 5. And that's it.
The second graph is the graph of the linear equation y = - 1/3x + 5.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given linear equation is y = - 1/3x + 5
We need to select the graph of the equation.
The slope of the line is -1/3
y intercept is 5.
Let us find few points to determine the graph.
if x=0, then y=-1/3(0)+5=5
So (0, 5) is one of the point
if x=1, then y=-1/3(1)+5
=14/3
(1, 14/3)
if x=2, then y=-1/3(2)+5
=13/3
(2, 13/3)
if x=3, then y=-1/3(3)+5
(3, 4) is point.
Now let us check these points which satisfy the graph.
Hence, the second graph is the graph of the linear equation y = - 1/3x + 5.

Which expression is equal to the length of the hypotenuse of a right triangle, formed inside the unit circle, with a radius of 1?
The length of the hypotenuse of a right triangle formed inside the unit circle with a radius of 1 is simply 1.
The expression equal to the length of the hypotenuse of a right triangle formed inside the unit circle, with a radius of 1, can be found using the Pythagorean theorem. In a unit circle, the hypotenuse of any right triangle formed by a radius will always have a length of 1, because the radius of a unit circle is 1 by definition. So, the expression you are looking for is simply 1, since the hypotenuse in this case is the radius of the circle.

A rectangle has an area of 112cm. The length and width of the rectangle are changed by a scale factor of 1.5. What is the area of the new rectangle?
Answer:
252 cm²
Step-by-step explanation:
Area of a rectangle is width times length:
A = WL
If the width and length increase by a factor of 1.5:
A = (1.5 W) (1.5 L)
A = 2.25 WL
So the area increases by a factor of 2.25.
2.25 × 112 cm² = 252 cm²

What banking service would be the most beneficial for a customer who just obtained a debit card?
0% financing
no ATM fees
$25 yearly fees
no overdraft protection
The most beneficial banking service for a customer with a new debit card would be no ATM fees, as this would save money on transactions, which is especially important given that banks tend to charge for non-interest income such as ATM and overdraft fees.
For a customer who just obtained a debit card, the most beneficial banking service would be no ATM fees. Debit cards give users the ability to access their funds through an ATM. Considering banks are profit-oriented and look to maximize non-interest income through various fees as described, ATM fees can be a frequent and unnecessary expense. ATM fees average $2.97 per transaction and can quickly accumulate, especially if withdrawals are made at out-of-network ATMs, which add even more to the cost. Therefore, selecting a banking service with no ATM fees would save the cardholder potential costs associated with accessing their money.
No overdraft protection would mean the cardholder could be charged substantial overdraft fees if they were to spend more than the balance in their checking account. Given that these fees can be very high, it's better to either have overdraft protection or manage the account carefully to avoid overdrafting. On the other hand, a $25 yearly fee is a fixed cost and might be worth it if the benefits provided surpass the fee, but it is generally an additional expense that can be avoided with careful account selection. Lastly, 0% financing is typically associated with credit cards rather than debit cards and the quoted 'introductory' rates can be misleading, often coming with hidden fees and high interest rates after the introductory period ends.

Answer:
[tex]cos(A) =\frac{3}{5}=0.6[/tex]
Step-by-step explanation:
By definition the cosine of an angle is the quotient between the side adjacent to the angle and the hypotenuse.
In other words:
[tex]cos (A) = \frac{adjacent}{hypotenuse}[/tex]
In this triangle the length of the side adjacent to the angle A is 30, and the length of the hypotenuse is 50
So:
[tex]cos(A) = \frac{30}{50}[/tex]
Simplifying we have that:
[tex]cos(A) = \frac{3}{5}=0.6[/tex]
Answer:
Final answer is [tex]\cos\left(A\right)=\frac{3}{5}[/tex].
Step-by-step explanation:
Using given information in the picture, we need ot find the missing value of Cos(A).
Apply formula of cosine function which is :
[tex]\cos\left(A\right)=\frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos\left(A\right)=\frac{30}{50}[/tex]
[tex]\cos\left(A\right)=\frac{3}{5}[/tex]

-16 ± 2√50 /2
-16 ± 10√2 /2
-8 ± 5√2
Answer: A) x=-8±5[tex]\sqrt{2}[/tex]
Step-by-step explanation: to find the solutions of the given equation, we need to use the substitution u=x+2, so the equation would now be:
[tex]u^{2} +12u-14=0[/tex]
the quadratic formula is:
u=(-b±[tex]\sqrt{b^{2}-4ac }[/tex])/2a
in this case a=1; b=12; and c=-14
so replacing the values it remains:
u=(-12±[tex]\sqrt{12^{2}-4*1*(-14) }[/tex])/2*1
u=(-12±[tex]\sqrt{144+56}[/tex])/2
u=(-12±[tex]\sqrt{200}[/tex])/2
we can write 200 as 100*2 and the square root of 100 is 10:
u=(-12±10[tex]\sqrt{2}[/tex])/2
u=-6±5[tex]\sqrt{2}[/tex]

The correct answers are:
A. P = 58 and Q = 78
C. P = -78 and Q = -52
D. P = 58 and Q = -78
To determine which values of P and Q result in the equation Px + 52 = Qx - 78 having exactly one solution, we need to ensure that the coefficients of x on both sides are not equal. This means P should not be equal to Q.
The given equation is:
Px + 52 = Qx - 78
First, let's rearrange the terms to isolate x:
Px - Qx = -78 - 52
(P - Q)x = -130
For this equation to have exactly one solution, P - Q must be non-zero. Therefore, P - Q.
Let's evaluate each option:
A. P = 58 and Q = 78
- P - Q = 58 - 78 = -20
- Since -20 is not zero, this pair results in exactly one solution.
B. P = 52 and Q = 52
- P - Q = 52 - 52 = 0
- Since 0 is zero, this pair does not result in exactly one solution.
C. P = -78 and Q = -52
- P - Q = -78 - (-52) = -78 + 52 = -26
- Since -26 is not zero, this pair results in exactly one solution.
D. P = 58 and Q = -78
- P - Q = 58 - (-78) = 58 + 78 = 136
- Since 136 is not zero, this pair results in exactly one solution.

(4) Plot the solution
Note where the lines cross.
They appear to intersect at (4, 10).
Plot the point, and the finished graph should look like Fig. 3.
Answer:
(2, 4)
Step-by-step explanation:
Both equations have been solved for y, so to find x we need only set the equations = to each other: y=-x+6 = y=3x-2
Combining like terms, we get 4x = 8, and x = 2. Substituting 2 for x in y = 3x -2, we get y = 3(2) - 2 = 4.
The solution is (2, 4). If you were to graph these two lines, you'd find that they intersect at (2, 4).
