Kendall and Ava lay out the course shown below for their radio-controlled trucks. In the figure, ΔABD ≅ ΔCBD. The trucks travel at a constant speed of 15 feet per second. How long does it take a truck to travel on the course from A to B to C to D? Round to the nearest tenth of a second.
The time taken for the truck to travel on the course from A to B to C to D is 9.3 s.
What is speed?The speed of an object is the ratio of the distance covered by the object while in motion to the time taken. It can be expressed as;
speed = distance/ time
So that given that ΔABD ≅ ΔCBD, then;
AB ≅ BC = 50 feet
Ad ≅ DC = 40 feet
BD = 30 feet
So that the total distance to be covered by the truck is;
AB + BC + CD = 50 + 50 + 40
= 140 feet
If the truck moves with a speed of 15 feet per second, time taken to cover the distance will be;
time = distance/ speed
= 140/ 15
= 9.3333
time = 9.33 seconds.
Therefore it will take the truck 9.3 seconds to cover the distance.

The midpoint of \overline{\text{AB}}
AB
is M(-5, -2)M(−5,−2). If the coordinates of AA are (-3, 4)(−3,4), what are the coordinates of BB?
Answer:
The coordinates of b are: B=(-7,-8)
Step-by-step explanation:
We are given the coordinates of the midpoint of \(\overline{\text{AB}}\) as M=(-5,-2).
We are also given the coordinates of A=(-3,4). The question requires us to calculate the coordinates of the other endpoint B.
Let (xb,yb) the coordinates of B. The coordinates of the midpoint can be calculated as follows:
\(\displaystyle x_m=\frac{x_a+x_b}{2}\)
\(\displaystyle y_m=\frac{y_a+y_b}{2}\)
We know xa=-3 and xm=-5. Solve the first equation for xb:
\(2x_m=x_a+x_b\Rightarrow x_b=2x_m-x_a\)
Substituting:
\(x_b=2\cdot (-5)-(-3)=-10+3\)
\(x_b=-7\)
We can solve the second equation for xb and get:
\(y_b=2y_m-y_a\)
Since ya=4 and ym=-2, then:
\(y_b=2\cdot (-2)-(4)=-4-4\)
\(y_b=-8\)
Thus, the coordinates of b are: B=(-7,-8)

A milk truck is driving around town. What is the volume of the milk truck?
Length: 6
Width: 4
Height: 6
Answer:
\(144\) cubic units
Step-by-step explanation:
We can assume that the truck is a rectangular prism since we're given its length, width, and height. To find the volume of a rectangular prism, simply multiply its length, width, and height together. As an algebraic expression, this would be \(l*w*h\), where \(l\), \(w\), and \(h\) are the prism's length, width, and height, respectively.
In this case, we are given that \(l=6\), \(w=4\), and \(h=6\). Therefore, the volume of the milk truck is \(6*4*6=144\) cubic units. Hope this helps!
Answer: 144 feet³
Step-by-step explanation: To find the volume, mutiply the Length, Width, and Height. Or we can use the formula.
Rectangular Tank Volume Formula: L x W x H
As we see, 6 is the Length. 4 is the Width and 6 is the Height.
So, we can multiply the Length, Width, and Height to get the volume.
6 x 4 x 6 = 144 feet³
Therefore, the answer is 144 feet³

30+2k+5k=100
What is k?
Answer:
k = 10
Step-by-step explanation:
30+2k+5k=100
Combine like terms
30 + 7k = 100
Subtract 30 from each side
30+7k-30 = 100-30
7k = 70
Divide each side by 7
7k/7 = 70/7
k = 10
Answer:
k=10
Step-by-step explanation:
We are given the equation:
30+5k+2k=100
We want to find k, therefore we must isolate k on one side of the equation.
First, combine like terms on the left side of the equation. 5k and 2k can be added together.
30+5k+2k=100
30+(5k+2k)=100
30+7k=100
30 is being added to 7k. The inverse of addition is subtraction. Subtract 30 from both sides of the equation.
30-30+7k=100-30
7k= 100-30
7k= 70
k is being multiplied by 7. The inverse of multiplication is division. Divide both sides by 7.
7k/7=70/7
k=70/7
k= 10
The solution to the equation 30+5k+2k=100 is k=10

How to obtain the value of x?In this problem, we have a right triangle, in which the legs, which are the sides between the angle of 90º, are of 11.9 cm and 7.9 cm.
Then the hypotenuse x, which is the segment connecting both legs, is obtained using the Pythagorean Theorem.
The Pythagorean Theorem states that the measure of the hypotenuse squared is equals to the sum of the squares of the measures of each side.
Then the length of x is calculated as follows:
x² = 11.9² + 7.9²
x = square root of (11.9² + 7.9²)
x = 14.28.
Closest to 14.3, rounding to the nearest tenth, meaning that the third option is correct.

Keenan will run 2.5 miles from his house to Jared’s house. He plans to hang out for 45 minutes before walking home. If he can run at 6 mph and walk 4 mph, how long will he be from home?
Answer:
Kennan will be from home approximately an hour and 48 minutes.
Step-by-step explanation:
We must know that total time (\(t_{T}\)) that Keenan will be from home is the sum of run (\(t_{R}\)), hang out (\(t_{H}\)) and walk times (\(t_{W}\)), measured in hours:
\(t_{T} = t_{R}+t_{H}+t_{W}\)
If Keenan runs and walks at constant speed, then equation above can be expanded:
\(t_{T} = \frac{x_{R}}{v_{R}}+t_{H}+ \frac{x_{W}}{v_{W}}\)
Where:
\(x_{R}\), \(x_{W}\) - Run and walk distances, measured in miles.
\(v_{R}\), \(v_{W}\) - Run and walk speeds, measured in miles per hour.
Given that \(x_{R}=x_{W} = 2.5\,mi\), \(v_{R} = 6\,\frac{mi}{h}\), \(v_{W} = 4\,\frac{mi}{h}\) and \(t_{H} = 0.75\,h\), the total time is:
\(t_{T} = \frac{2.5\,mi}{6\,\frac{mi}{h} } + 0.75\,h+\frac{2.5\,mi}{4\,\frac{mi}{h} }\)
\(t_{T} = 1.792\,h\) (\(1\,h\,48\,m\))
Kennan will be from home approximately an hour and 48 minutes.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.
What are scatterplots?A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.
Scatter plot for the positive correlationScatter plot for negative correlationScatter plot for null correlationA weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

B. Y= 3cos(x+pi)
C. Y= 3sin(x-pi)
D. Y= 3cos(x-pi)
Answer:
its c ! just took the test :)
Option C is correct. The equation that matches the function shown in the graph is expressed as y = 3sin(x-π)
The general formula for a sine function is expressed as;
y = Asin(x+Ф)
A is the amplitude i.e the maximum point on the curve. From the diagram, we can see that the maximum point is at 3 (factor 3 elongates the curve).
A = 3
Also, since the graph translates to the right by π, hence Ф = -π
Substituting the resulting values into the formula, we will have;
y =3sin(x+ (-π))
y = 3sin(x-π)
Hence the equation that matches the function shown in the graph is expressed as y = 3sin(x-π)

A -10 nC charge is located at (x, y) = (1.2 cm , 0 cm).
What is the x-component of the electric field at the position (x, y) = (−4.1cm, 0 cm)?Express your answer to two significant figures and include the appropriate units.
We can use Coulomb's law to calculate the magnitude of the electric field at a distance r away from a point charge Q:
E = k * Q / r^2
where k is Coulomb's constant, Q is the charge of the point charge, and r is the distance from the point charge.
In this problem, we have a point charge Q of -10 nC located at (1.2 cm, 0 cm), and we want to find the x-component of the electric field at a distance r = 5.3 cm away at position (-4.1 cm, 0 cm).
To find the x-component of the electric field, we need to use the cosine of the angle between the electric field vector and the x-axis, which is cos(180°) = -1.
So, the x-component of the electric field at position (-4.1 cm, 0 cm) is:
E_x = - E * cos(180°) = - (k * Q / r^2) * (-1)
where k = 9 x 10^9 N*m^2/C^2 is Coulomb's constant.
Substituting the given values, we get:
E_x = - (9 x 10^9 N*m^2/C^2) * (-10 x 10^-9 C) / (0.053 m)^2
E_x ≈ -30,566.04 N/C
Rounding this to two significant figures and including the appropriate units, we get:
The x-component of the electric field is about -3.1 x 10^4 N/C (to the left).

The trigonometric ratio for the tangent of an angle indicates that the tangent of the angle ∠B expressed as an improper fraction is expressed in the form;
tan(∠B) = \(2\frac{2}{39}\)
What is the tangent of an angle?The tangent of an angle in a triangle is the ratio of the facing side to the adjacent side of the triangle.
The type of triangle in the figure with an interior angle of 90 degrees is a right triangle, therefore, according to the Pythagorean Theorem, we get;
(AC)² + (AB)² = (BC)²
Therefore, we get;
(AC)² + 39² = 89²
(AC)² = 89² - 39² = 6400
AC = √(6400) = 80
The tangent of an angle is the ratio of the opposite side to the adjacent side, therefore;
