Bobby drives his truck at a rate of 50 to 60 miles per hour.
a. Approximately how far can Bobby drive in 2, 3, 4, and 5 hours?
b. Bobby plans to take an 8-hour trip, which will include a 1-hour stop for
lunch. What is a reasonable distance for Bobby to drive?
a. 2 hours = 100 to 120m
3 hrs = 150 to 180m
4 hrs = 200 to 240m
5 hrs = 250 to 300m
b. 400 to 480 miles
Bobby can drive between 50 times the number of hours and 60 times the number of hours depending on the drive duration. For an 8-hour trip with a 1-hour lunch stop, he drives for 7 hours, covering between 350 and 420 miles.
Explanation:a) Bobby's driving speed varies between 50 to 60 miles per hour. Therefore:
If he drives for 2 hours, at the minimum speed he can cover 50*2=100 miles, and at the maximum speed, he can cover 60*2=120 miles.If he drives for 3 hours, the range is between 50*3=150 miles and 60*3=180 miles.If he drives for 4 hours, the range is between 50*4=200 miles and 60*4=240 miles.And if he drives for 5 hours, the range is between 50*5=250 miles and 60*5=300 miles.b) For an 8-hour trip with a 1-hour stop for lunch, Bobby will effectively be driving for 7 hours. So, the minimum distance he could cover is 50*7=350 miles and the maximum distance is 60*7=420 miles.

Write an exponential function in the form of y=ab^x that goes through points (0,6) and (2,96)
Final answer:
The exponential function that goes through the points (0,6) and (2,96) is y = 6 * 4^x, where 6 is the initial value (a) and 4 is the base growth rate (b).
Explanation:
The student is asking for an exponential function in the form y = ab^x that passes through the points (0,6) and (2,96).
To find this function, we must determine the values of 'a' and 'b'. Since the function passes through the point (0,6), if we substitute x = 0, we get y = a * b^0. Since any number raised to the power of 0 is 1, it simplifies to y = a. Therefore, a = 6.
Next, we substitute the second point (2,96) into the original equation with our known value for 'a': 96 = 6 * b^2. To solve for 'b', we divide both sides of the equation by 6, resulting in 16 = b^2. Finding the positive square root of 16 gives us b = 4.
Therefore, the exponential function is y = 6 * 4^x.
The exponential function that goes through the points [tex]\((0, 6)\)[/tex] and [tex]\((2, 96)\)[/tex] is [tex]y = 6 \times 4^x[/tex]
To find the exponential function in the form [tex]\( y = ab^x \)[/tex] that goes through the points [tex]\((0, 6)\)[/tex] and [tex]\((2, 96)\)[/tex], we need to determine the values of [tex]\(a\)[/tex] and [tex]\(b\)[/tex].
1. Use the point [tex]\((0, 6)\)[/tex]
When [tex]\( x = 0 \), \( y = 6 \).[/tex]
[tex]\[6 = ab^0\][/tex]
Since [tex]\( b^0 = 1 \)[/tex]
[tex]\[6 = a \times 1\][/tex]
Therefore, [tex]\( a = 6 \).[/tex]
2. Use the point [tex]\((2, 96)\)[/tex]
When [tex]\( x = 2 \), \( y = 96 \)[/tex]
[tex]\[96 = 6b^2\][/tex]
Solving for [tex]\( b^2 \)[/tex]
[tex]\[b^2 = \frac{96}{6} = 16\][/tex]
Taking the square root of both sides:
[tex]\[b = 4\][/tex]
Thus, the exponential function is:
[tex]\[y = 6 \times 4^x\][/tex]
To verify, we can check both points:
For [tex]\((0, 6)\)[/tex]
[tex]\[y = 6 \times 4^0 = 6 \times 1 = 6\][/tex]
For [tex]\((2, 96)\)[/tex]
[tex]\[y = 6 \times 4^2 = 6 \times 16 = 96\][/tex]
A conical glass flower vase has a base that is 6 inches in diameter and a vase that holds approximately 113 in.³ of water what is the height of the vase?
To find the height of the vase, use the formula for the volume of a cone (V = (1/3)πr^2h) and solve for h. Given the base diameter and the volume of the vase, substitute the values into the formula to find the height. The height of the vase is approximately 4 inches.
Explanation:To find the height of the vase, we can use the formula for the volume of a cone which is V = (1/3)πr^2h, where V is the volume, r is the radius of the base, and h is the height. Given that the base of the vase has a diameter of 6 inches, the radius is half the diameter, which is 3 inches. We also know that the volume of the vase is approximately 113 in.³. We can substitute these values into the formula to find the height:
V = (1/3)π(3^2)h
113 = (1/3)π(9)h
113 = (3/3)π(9)h
113 = (π)(9)h
h = 113 / (π)(9)
h ≈ 4 inches
Therefore, the height of the vase is approximately 4 inches.

A triangle with an area of 3 mm squared is dilated by a factor of 6. What is the area of the dilated triangle?
By definition, the area of a triangle is given by:
A = (1/2) * (b) * (h)
Where,
b: base
h: height
The area of the original triangle is 3 mm² and is dilated by a factor of 6. We have then
A = (1/2) * (6b) * (6h)
A = (1/2) * (b) * (h) * (6) * (6)
A = 3 * (6) * (6)
A = 108 mm²
answer
The area of the dilated triangle is 108 mm²
When a triangle with an original area of 3 mm squared is dilated by a factor of 6, the new area is found by multiplying the original area by the square of the dilation factor. This results in a new area of 108 mm squared.
The question asks about the effect of dilation on the area of a triangle. Specifically, it asks for the new area if a triangle with an original area of 3 mm² is dilated by a factor of 6. When dealing with dilation, the area of a shape changes by the square of the dilation factor. This means that if the dilation factor is 6, the new area will be 62 times the original area. This calculation can be performed as follows:
Original area = 3 mm²
Dilation factor = 6
New area = Original area × (Dilation factor)2 = 3 mm² × 62
New area = 3 mm² × 36 = 108 mm2
Therefore, the area of the dilated triangle is 108 mm²
Determine and state an equation of the line perpendicular to 5x-4y=10nand passing through point (5,12).
Answer:
4x + 5y = 80
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x - 4y = 10 into this form
Subtract 5x from both sides
- 4y = - 5x + 10 ( divide all terms by - 4 )
y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{5}{4}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{4} }[/tex] = - [tex]\frac{4}{5}[/tex], thus
y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, 12) into the partial equation
12 = - 4 + c ⇒ c = 12 + 4 = 16
y = - [tex]\frac{4}{5}[/tex] x + 16 ← in slope- intercept form
Multiply through by 5
5y = - 4x + 80 ( add 4x to both sides )
4x + 5y = 80 ← in standard form
The equation of line perpendicular to [tex]5x-4y=10[/tex] and passing through the point (5,12) is [tex]y=-\frac{4}{5}+16[/tex]
The line given in the problem is in Standard Form. The standard form of a linear equation is: [tex]Ax+By=C[/tex]
Where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.
[tex]5x-4y=10[/tex]
The slope of an equation in standard form is: [tex]m=-\frac{A}{B}[/tex]. Substituting the values from the equation in the problem gives:
[tex]m=-\frac{5}{(-4)} =\frac{5}{4}[/tex]
Let's call the slope of the line perpendicular to this line [tex]m_{p}[/tex] . The slope of a perpendicular line is:
[tex]m_{p} =-\frac{1}{m} =-\frac{4}{5}[/tex]
We can now use the point-slope formula to find the equation of the line. The point-slope formula states: [tex](y-y_{1})=m(x-x_{1})[/tex]
[tex]y-12=-\frac{4}{5} (x-5)[/tex]
[tex]5(y-12)=-4(x-5)\\5y-60=-4x+20\\5y=-4x+80\\y=-\frac{4}{5}x+16[/tex]
Therefore, the equation of line perpendicular to [tex]5x-4y=10[/tex] and passing through the point (5,12) is [tex]y=-\frac{4}{5}+16[/tex]

Measure of ∠B is 110°
Step-by-step explanation:
Step 1: Find ∠B of the parallelogram.In a parallelogram, opposite angles are equal.
⇒ ∠B = ∠D
⇒ ∠B = (5x + 10)°
Step 2: Use theorems of quadrilaterals to form equations to find x and y.Now, angles in a parallelogram are equal to 360°.
⇒ ∠A + ∠B + ∠C + ∠D = 360°
⇒ (3x + y)° + (5x + 10)° + (5y + 20)° + (5x + 10)° = 360°
⇒ 13x + 6y + 40° = 360°
⇒ 13x + 6y = 320° ------ (1)
Also, adjacent angles in a parallelogram are supplementary.
⇒ ∠A + ∠D = 180°
⇒ (3x + y)° + (5x + 10)° = 180°
⇒ 8x + y = 170° ----------- (2)
Step 3: Solve the 2 equations to find x and y.13x + 6y = 320
48x + 6y = 1020 (After multiplying eq. 2 with 6 to make coefficients equal)
Subtract (2) from (1)
⇒ -35x = -700
∴ x = 20
⇒ (5x + 10)° = 100 + 10 = 110°
Answer:
110°
Step-by-step explanation:
Angle A = Angle C
3x + y = 5y + 20
3x = 4y + 20
Angle C + Angle D = 180
5y + 20 + 5x + 10 = 180
5x + 5y = 150
x + y = 30
x = 30 - y
3(30 - y) = 4y + 20
90 - 3y = 4y + 20
7y = 70
y = 10
x = 30 - 10
x = 20
Angle B = Angle D
= 5(20) + 10
