How do you do this question?
Answer:
(8√2) / 15
Step-by-step explanation:
A curve bounded by the y-axis is represented by in terms of dy;
[tex]\int \:x\:dt[/tex]
When the curve crosses the y-axis, x will be 0. In this case x is the function of t, so we have to solve for x(t) = 0;
0 = t^2 + 2t --- (1)
Solution(s) => t = 0, t = 2
dy = (1/2 * 1/√t)dt --- (2)
Our solutions (0, 2) are our limits. The area of the curve is in the form [tex]A\:=\:\int _b^a\:f\left(t\right)g'\left(t\right)dt[/tex] , so now let's introduce the limits of integration, x(t) and dy/dt. Remember, dy/dt = (1/2 * 1/√t) (second equation). 1/2 * 1/√t can be rewritten as 1/2 * t^(-1/2)....
[tex]A\:=\:\int _2^0\:\left(t^2-2t\right)\left(\frac{1}{2}t^{-\frac{1}{2}}\right)dt\\\\= \int _2^0\:\left(\frac{1}{2}t^{\frac{3}{2}}-t^{\frac{1}{2}}\right)dt\\\\= \left[\frac{t^{\frac{5}{2}}}{5}-\frac{2t^{\frac{3}{2}}}{3}\right]_2^0\\\\= 0\:-\:\left(\frac{4\sqrt{2}}{5}-\frac{4\sqrt{2}}{3}\right)\\\\= \frac{8\sqrt{2}}{15}[/tex]
Your solution is 8√2 / 15

-3x + 8 = 17 and 1 + 4x = -15
Answer:
1) x= -3
2) x=-4
Step-by-step explanation:
The first equation is :
-3x+8=17
solving for x
-3x=17-8 ------------by collecting like terms
-3x=9
Divide both sides by -3
-3x/-3=9/-3
x= -3
In the second equation
1+4x= -15
solving for x
4x=-15-1
4x = -16
x=-16/4
x= -4

Which graph I-IV matches with a?
Answer:
III
Step-by-step explanation:
At t = 0, x = 1.
At t = 0.5, x = 2.
At t = 1, x = 1.
The curve is symmetrical.
The graph that fits is III. x starts at 1, increases 2, then decreases at the same rate back to 1.

A. Census
B. Sample survey
C. Simulation
D. Experiment
Answer:
C. Simulation
Step-by-step explanation:
The answer is Simulation the modeling events using random numbers is known as a simulation option (C) Simulation is correct.
What is a survey?A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
It is given that:
Modeling events using random numbers is known:
As we know, a simulation recreates random occurrences by specifying event outcomes with relative frequencies that match the real-world relative frequencies we're aiming to simulate using random numbers.
It's called a simulation when you use random numbers to model an event.
Modeling events using random numbers is known as a simulation.
Thus, the answer is Simulation the modeling events using random numbers is known as a simulation option (C) Simulation is correct.

Step-by-step explanation:
Gillian’s Restaurant has an ice-cream counter where it sells two main products, ice cream and frozen yogurt, each in a variety of flavors. The restaurant makes one order for ice cream and yogurt each week, and the store has enough freezer space for 115 gallons total of both products. A gallon of frozen yogurt costs $0.75 and a gallon of ice cream costs $0.93, and the restaurant budgets $90 each week for these products. The manager estimates that each week the restaurant sells at least twice as much ice cream as frozen yogurt. Profit per gallon of ice cream is $4.15, and profit per gallon of yogurt is $3.60.
