Here Tran 1 more I appreciate it
Step-by-step explanation:
The top and bottom horizontal lines are 11 units long and the left and right vertical lines are 9 units long. Dilating the logo by a factor of one-half means that these lengths will grow longer by 50%. Hence the horizontal lines will get longer by 5.5 units and vertical lines will grow longer by 4.5 units. The diagonals should also increase in length accordingly.

Step-by-step explanation:
Find the possible value of "a" using the distance formula.
(4,-1) and (a,5) with d = 10
Answer:
[tex]a=12\text{ or } -4[/tex]
Step-by-step explanation:
The distance formula is given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We are given the two points (4, -1) and (a, 5). The distance between them is 10.
Let (4, -1) be (x₁, y₁) and let (a, 5) be (x₂, y₂). Substitute:
[tex]10=\sqrt{(a-4)^2+(5-(-1))^2}[/tex]
Solve for a. Square both sides and simplify:
[tex]100=(a-4)^2+(6)^2[/tex]
Simplify:
[tex]64=(a-4)^2[/tex]
Take the square root of both sides. Since we are taking an even root, we will need plus/minus. Hence:
[tex]\pm\sqrt{64}=\pm8=a-4[/tex]
Solve for a:
[tex]a-4=8\Rightarrow a=12\text{ or } a-4=-8\Rightarrow a=-4[/tex]
So, our two possible points are (12, 5) or (-4, 5).
Given () = −^3 + 2^2 +(3/2) be the position of a particle moving along the x-axis at time t. At what time will the instantaneous velocity equal the average velocity over the time interval [0, 4]
Answer:
5.266 secs
Step-by-step explanation:
Lets assume ; p(t) = t^-3 + 2^2 + ( 3/2 ) is the particle position along x-axis
time interval [ 0, 4 ]
Average velocity = Displacement / time
= p( b ) - p( a ) / b - a -------- ( 1 )
where a = 0 , b = 4 ( time intervals )
Back to equation 1
Average velocity = [ ( 4^-3 + 4 + (3/2) ) - ( 0 + 4 + (3/2) ) ] / 4
= 3.9 * 10^-3 ----- ( 2 )
Instantaneous velocity = d/dx p(t)
= - 3/t^4 ------ ( 3 )
To determine the time that the instanteous velocity = average velocity
equate equations (2) and (3)
3.9*10^-3 = - 3 / t^4
t^4 = - 3 / ( 3.9 * 10^-3 ) = - 769.231
hence t = [tex]\sqrt[4]{- 769.231 }[/tex] = 5.266 secs
we ignore the negative sign because time can not be in the negative

Four streets feed into a roundabout circle as shown below. If the diameter of the
roundabout is 130 feet, find the approximate distance a car will travel between Cole Street
and Maple Street along the roundabout.
Answer:
The answer is C. 119.1
Step-by-step explanation:
The arch measure between Cole St. and Maple St. is 105 degrees which is equal to 7/24 of the circumference. since the diameter is given simply multiply the circumference by 7/24 which equals 285,887/2400. Divide these and you get your answer.

A box in the shape of a rectangular prism has a length of 3 5/8 inches, a width of 2 1/2 inches, and a height of 4 inches. What is the volume of the box?
Answer:
36 1/4 in³
Step-by-step explanation:
v = 3 5/8 * 2 1/2 * 4
Convert to improper fractions
v = 29/8 * 5/2 * 4/1
Cancel
v = 29/2 * 5/2 * 1/1
Multiply
v = 145/4
Reduce
v = 36 1/4 in³
Karen borrowed a sum of money for some big screen TVs and a waterfall for her restaurant. If she borrowed $10,200 and received a 3.85 % interest rate compounded continuously, how much did Karen pay in interest over a 7 year period? Round your answer to the nearest whole number
Answer:
3155
Step-by-step explanation:
Continously compounding interest formula:
PV*e^(rt)
10200*e^(.0385*7)=13354.95825
To find the amount of interest paid subtract the original amount
13354.95825-10200=3154.958249
which rounds to
3155
A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
1 km = 1000 meters.
Find total meters: 80 km x 1000 meters per km = 80,000 meters.
Divide total meters by the given speed:
80,000 meters / 180 m/s = 444.44 seconds.
1 minute = 60 seconds
444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds
Total time = 7 minutes 24.42 seconds
Round as needed.

What is the slope of the line graphed
above?
I need help with geometry
Answer:
146
Step-by-step explanation:
angle AB is an inscribed angle and arc AB is it's intercepted arc
An inscribed angle is equal to half the measure of its intercepted arc
Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle
Thus, arc ab = 2(73)
2 * 73 = 146
hence, arc AB = 146
Answer:
mAB = 146°
Step-by-step explanation:
We can notice that the angle given is an inscribed angle and an inscribed angle is 1/2 the arc it intercepts. We can set up an equation to model the situation:
73° = 1/2(mAB)
mAB = 146°

The sum of two numbers is 65. The larger number is five more than three times the smaller number. What are the numbers? (Systems of Equations)
Answer:
x=44 and y=21
Step-by-step explanation:
The large one is x
The small one is y
According to given conditions,
x+y=65[Sum of two number is 65]—Equation(1)
x-23=y [Smaller number is less than 23 than larger]——Equation (2)
From equation (2) we can write,
x-y=23——-Equation(3)
Now adding equation (1) and (3) we get,
x+y+x-y=65+23
=>2x=88
=>2x/2=88/2 [Both sides are divided by 2]
=>x=44
Now putting the values in equation (2) we get,
44–23=y
=>y=21
Large, x=44 and Small, y=21
Aquarium has a height of 25 inches and a radius of 21 inches what is the volume of the aquarium in cubic inches
Answer:[tex]34,650\ in^3[/tex]
Step-by-step explanation:
Given
The height of the aquarium is [tex]h=25\ inches[/tex]
The radius of the aquarium is [tex]r=21\ inches[/tex]
Assuming aquarium to be in the shape of a cylinder
So, its volume is [tex]V=\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 21^2\times 25\\\Rightarrow V=34,650\ in^3[/tex]
Thus the volume of the aquarium is [tex]34,650\ in^3[/tex].
