Answer:
after 11.07secs
Step-by-step explanation:
Given the height of an object modeled by the equation
H = 16T² - 1960
The height of the object on the surface of water is zero, hence H = 0
Substitute
0 =16T² - 1960
Swap
16T² - 1960 = 0
16T² = 1960
T² = 1960/16
T² = 122.5
T = 11.07
Hence the rock will hit the surface of the water after 11.07secs
The next model of a sports car will cost 5.9% more than the current model. The current model costs $36,000.
How much will the price increase in dollars?
What will be the price of the next model?
Answer:
38124 :: 2124
Step-by-step explanation:
36,000*0.059 = $2124 increase
36,000 + 2124 = $38,124 cost
Answer:
$2124 increase
$38,124 cost

Answer:
X=5
Step-by-step explanation:
Answer:
X would be 6
Step-by-step explanation:
In the first step, it asked what 3-2 times (x+3), x in this part is six,
So that get us 9,
Finally in the second step 18-9= 9

Luke is designing a scale model of a clock tower. The design of the front of the tower is shown below.
A figure can be broken into a triangle and rectangle. The rectangle has a base of 200 millimeters and height of 50 millimeters. The triangle has a base of 50 millimeters and height of 100 millimeters.
What will be the area of the front face of his model?
2,500 square millimeters
10,000 square millimeters
12,500 square millimeters
15,000 square millimeters
The answer is 2,500. You must multiply both of the equations and add them together. The answer will be 2500.
Answer:
Answer:
Option B - 10,000 square millimeters
Step-by-step explanation:
From the image attached, we see that the dimensions of the front of the tower are;
Length; L = 200 mm
Width; w = 50 mm
Now, this front face takes the shape of a rectangle.
Area of rectangle = Length x width
Thus, plugging in the values of length and width, we will get;
Area of front face = 200 x 50
Area of front face = 10,000 square millimeters

The general term of a sequence is given by an = 7+3 (n − 1) for n > 1.
Which recursive formula defines this sequence?
Answer:
The fifth term is 8.
Step-by-step explanation:
Give n=5 in the general term
T 5=3(5)-7 = 15–7 =8
Another method
Tn = 3n - 7
T 1 = 3(1)-7 = -4
T 2 = 3(2) -7= -1
d= t 2 - t 1 = -1 -(-4)=3
a = -4 d=3
Tn = a + (n-1)d =
T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8

If a point is randomly picked inside the square, what is the
probability that it will be inside the circle? Round your answer to
the nearest percent.
Answer:
I would say around 45% chance it is in there while I'm just assuming because the circle is just a little less than half the square

In a class of 7, there are 2 students who are martial arts masters.
If the teacher chooses 2 students, what is the probability that both of them
are martial arts masters?
Answer:
1/21
Step-by-step explanation:
First, find the possible number of combinations of 2 students picked from 7 since order does not matter:
7 choose 2 = 7 nCr 2 = 7!/2!(7-2)! = 5040/2(120) = 5040/240 = 21
Because there's only one combination where both students are martial arts masters, the probability of selecting 2 students out of 7 given that 2 of the 7 are martial art masters is 1/21.
