GUYS PLEASE HELP ASAP!!!!!!! A car is driving 18 meters per second. It then merges on to a highway and accelerates at a rate of 6 meters per second per second for 2.0 seconds. It then remains at this speed. What is the speed of the car on the highway?
a. 3.0 m/s
b. 12.0 m/s
c. 26.0 m/s
d. 30 m/s
Answer:
it is going to be B. 10 m/s
The speed of the car on the highway will be 30 m/s
What is acceleration?The rate at which velocity changes with time, in terms of both speed and direction.
Given that, a car is driving 18 meters per second. It then merges on to a highway and accelerates at a rate of 6 meters per second for 2.0 seconds.
Using first equation of motion,
v = u + at where, v is final velocity, u is initial velocity, a is acceleration and t is time,
v = 18 + 6*2
v = 18 + 12
v = 30
Hence, speed of the car on the highway will be 30 m/s

What is “F” in this triangle problem thingy
Answer:
f=43
Step-by-step explanation:
Hey There!
So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles
so essentially what i am saying is that
19+24=f
19+24=43
therefore
f=43
hope this helps :)
if you have anymore questions just let me know
What is the area of this figure?
Enter your answer in the box.
Answer:
84
Step-by-step explanation:
square: 6mm * 6mm = 36mm
triangle 1: (8mm * 6mm) 0.5 = 24mm
triangle 2: (8mm * 6mm) 0.5 = 24mm
add all of it up to get the entire area
36 + 24 + 24 = 84

Answer: 1. A) 2/5 B) X= -5 Y= 2
2. A) -3/2 B) X= 2 Y= 3
3. A) -2/3 B) X= -3 Y= -2
Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.
B) This is where the line intersects the X and Y axis

A. 109°
B. 34.5°
C. 62.5°
D. 69°
Show work, if possible. Thanks❤️
Answer:
Angle k is 34.5 degrees
Step-by-step explanation:
a circle makes 360 degrees total. okay so u have to consider the angles given. m arc go= 127
m<0 = 54.5
54.5 times 2 = 109
109 is arc gk
109 + 127+ 55= 291
360-291=69= arc OU
69 divided by 2 is 34.5
Angle k is 34.5 degrees

Answer:
x ≈ 10.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{x}[/tex] ( multiply both sides by x )
x × sin40° = 7 ( divide both sides by sin40° )
x = [tex]\frac{7}{sin40}[/tex] ≈ 10.9 ( to the nearest tenth )

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an equation of line L
Given:
The equation of given line is
[tex]y=3x-4[/tex]
A line is perpendicular to the given line and passes through the point (9,5).
To find:
The equation of the perpendicular line.
Solution:
We have,
[tex]y=3x-4[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=3[/tex]
It means, the slope of the given line is 3.
The product of slopes of two perpendicular lines is -1.
[tex]m\times m_1=-1[/tex]
[tex]3\times m_1=-1[/tex]
[tex]m_1=-\dfrac{1}{3}[/tex]
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope.
The slope of perpendicular line is [tex]-\dfrac{1}{3}[/tex] and it passes through the point (9,5). So the equation of the line is
[tex]y-5=-\dfrac{1}{3}(x-9)[/tex]
[tex]y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)[/tex]
[tex]y-5=-\dfrac{1}{3}x+3[/tex]
Adding 5 on both sides, we get
[tex]y-5+5=-\dfrac{1}{3}x+3+5[/tex]
[tex]y=-\dfrac{1}{3}x+8[/tex]
Therefore, the equation of required line is [tex]y=-\dfrac{1}{3}x+8[/tex].

A sequence can be generated by using an = 4a(n - 1)) where a= 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
Given:
The sequence can be generated by
[tex]a_n=4a_{(n - 1)}[/tex]
Where [tex]a_1= 6[/tex] and [tex]n[/tex] is a whole number greater than 1.
To find:
The first four terms of the given sequence.
Solution:
We have,
[tex]a_n=4a_{(n - 1)}[/tex] ...(i)
It is given that [tex]a_1= 6[/tex]. So, for [tex]n=2[/tex], we get
[tex]a_2=4a_{(2 - 1)}[/tex]
[tex]a_2=4a_1[/tex]
[tex]a_2=4(6)[/tex]
[tex]a_2=24[/tex]
Putting [tex]n=3[/tex] in (i), we get
[tex]a_3=4a_{(3- 1)}[/tex]
[tex]a_3=4a_2[/tex]
[tex]a_3=4(24)[/tex]
[tex]a_3=96[/tex]
Putting [tex]n=4[/tex] in (i), we get
[tex]a_4=4a_{(4- 1)}[/tex]
[tex]a_4=4a_3[/tex]
[tex]a_4=4(96)[/tex]
[tex]a_4=384[/tex]
The first four terms of the given sequence are 6, 24, 96,384.
Therefore, the correct option is C.

If the radius and the slant height of this right circular cone are each multiplied by 4, by what factor is the surface area multiplied?
Answer:
16
Step-by-step explanation:
Total surface area of a cone T1 = πr(r+l)
If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;
T1 = π4r(4r+4l)
T2 = 16πr(r+l)
Taking the ratio of both total area
T1/T2 = πr(r+l)/16πr(r+l)
T1/T2 = 1/16
16T1 = T2
T2 = 16 T1
Hence the total surface area is multiplied by a factor of 16

The price of an oven was increased by 20% to £156.
What was the price before the increase?
Answer:
Step-by-step explanation:
Before the increase it was 100%
So 20+100=120
156/120*100=130$
Don’t do it like 20/100 *156 and then minus it from 156 because you will get a wrong answer
(This was answered by another person on a another question.)
Answer:
130
Step-by-step explanation:
x * 1.2 = 156
x = 156/1.2
x = 130
