It is 5! you do 35 divided by 5 it is 7
We are given the area of the region under the curve of the function f(x) = 5x + 7 with an interval [1, b] which is 88 square units where b > 1
We need to find the integral of the function f(x) = 5x + 7 with the limits 1 and b
5/2 x^2 + 7x (limits: 1, b)
substitute the limits:
5/2 (1^2) + 7 (1) - 5/2 b^2 + 7b = 0
solve for b
Then after solving for b, this would be your interval input with 1: [1, b].<span />
Answer:
51 minutes.
Step-by-step explanation:
We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.
We will use proportions to solve our given problem.
Upon substituting our given values, we will get:
Therefore, Leila has been watching TV together for 51 minutes.
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
The distance of the plane flies between the two cities is 1,113.75 miles
The formula for calculating the distance travelled is expressed as:
D = vt where:
v is the speed
t is the time taken
Given the following:
v = 99mi/hr
Total time taken = 5hr + 6.25hr
Total time taken = 11.25hr
Get the required distance
Distance = 99mi/hr * 11.25hr
Distance = 1,113.75miles
Hence the distance of the plane flies between the two cities is 1,113.75 miles
