The graphs are exactly the same, EXCEPT that the graph of y=sqrt(x) has to be translated 3 units down to obtain the graph of y=sqrt(x)-3.
Answer:
C / (2pi) = r; r= 13.9 cm
2A/b = h ; h= 5
Step-by-step explanation:
The formula for the circumference of a circle is C = 2* pi * r.
Solving for r, we need to divide by 2 * pi on each side
C/(2* pi) = 2*pi*r/ (2* pi)
C / (2pi) = r
If the circumference is 87, we can find r by substituting into the equation.
87 / (2 * 3.14) = r
87/ 6.28 = r
13.85350318=r
Rounding to the nearest tenth
r= 13.9 cm
The formula for the area of a triangle is A = bℎ /2
To solve the formula for h, we need to multiply each side by 2
2*A = bh
Then divide each side by b
2A/b = bh/b
2A/b = h
If the area of a triangle is 25 and the base of 10 , we can substitute in to find the height.
2* 25 /10 = h
50/10 = h
5 =h
Answer: Her account would earn $17.5
Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;
Interest = PRT/100
Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,
Interest = (50 x 3.5 x 10)/100
Interest = 1750/100
Interest = 17.5
Therefore, in 10 years her account would have earned $17.5
4/5 and 40/50 are both equivalent
<u>Answer:</u>
P(A') = 0.75
<u>Step-by-step explanation:</u>
We are given that the probability P(A) = 0.25 and we are to determine the probability of the complement of A.
According to the Complement Rule of any probability, the sum of the probabilities of an event and its complement must be equal to 1.
So for for the event A,
P(A) + P(A') = 1
0.25 + P(A') = 1
P(A') = 1 - 0.25
P(A') = 0.75
