Below in bold
Step-by-step explanation:
∫ dx / (x^2√(9-x^2))
Substitute x = 3sinu and dx = 3cosu du
then the √(9-x^2) = √( 9 - 9sin^2u) = 3 cos u and u = arcsin(x/3)
= 3 ∫(csc^2 u du )/ 27
= 1/9 ∫(csc^2 u du
= -1/9 cot u
= -√9-x^2) / 9x.

The answer is B) y = 4x
Explanation: If you substitute each number in the x column for the variable x, and then multiple that number by 4, you'll get the number in the y column to the right.
For example:

Answer:
[tex]\huge\boxed{B)\ x<-1}[/tex]
Step-by-step explanation:
Solve this inequality the same way you would solve an equation: by isolating x.
Simply subtract 6 from both sides to get -4x > 4. Then merely divide both sides by -4 to get x < -1. (Notice that when dividing by a negative number, you must flip the sign of the inequality.)

Answer:
Y = 10/7X + 4
Y intercept = 4
Slope = 10/7
X intercept = -40/7
Step-by-step explanation:
Incase you are asked the equation of the line
The slope intercept equation is as follows -
(1)....Y = mx + b
where m - Slope
b - Y - intercept
the standard formula of slope which is commonly referred to as "the rate of change" is -
(2) .....m= Y2 - Y1 / X2 - X1
in this case you can refer to the final and initial X and Y values directly from the small points on the line.
and so(3)..... - X1 = -6 X2 = 6
- Y2 = 9 Y1 = -1
the y intercept is defined as the value we get whenever X id zero. and X has a value of zero when a line crosses the y axis.
thus, X = 0 & Y = 4 ( 0 , 4 )
now lets substitute our values(3) into the slope formula (equation 2)
m = 9 - - 1 / 6 - - 1 = 10/7
now that we found the line's slope, let's simply plug the y intercept
into the slope intercept formula (1)
Y = 10/7X + 4

Which expressions are equivalent when m = 1 and m = 4? 5 m minus 3 and 2 m 5 m 3 m 4 and m 4 2 m 2 m 7 and 3 m minus 3 m 5 m 3 and 4 m 2 2 m.
Answers
Answer:
Step-by-step explanation:
The expressions that are equivalent when m = 1 and m = 4 is;
Option B: 3m + 4 and m + 4 + 2m
We are given m = 1 and m =4;
A) 5m - 3 and 2m + 5 + m
B) 3m + 4 and m + 4 + 2m
C) 2m + 7 and 3m - 3 + m
D) 5m + 3 and 4m + 2 + 2m
For option B; 3m + 4 and m + 4 + 2m
Let's put m = 1
3(1) + 4 = 7
Also, 1 + 4 + 2(1) = 7
Similarly, let us put 4 for m to get;
3(4) + 4 = 16
Also, 4 + 4 + 2(4) = 16
In both cases, the expressions are equivalent and as such option B is the right one.

D y = 1/2x + 3
Answers
Answer:
Solution given:
slope(m)=½
passing through point (x',y')=(0,3)
now
equation of a line is:
y-y'=m(x-x')
y-3=½(x-0)
y=½x+3
D.y=½x+3 is a required equation of a line.
Hanna has 88cm of ribbon and cuts it in the ratio 5 : 6. How much longer is the longest piece and the shortest piece?
Answers
Answer:
8 cm
Step-by-step explanation:
sum the parts of the ratio, 5 + 6 = 11 parts
Divide the length of ribbon by 11 to find the value of one part of the ratio
88 cm ÷ 11 = 8 cm ← value of 1 part of the ratio , then
5 parts = 5 × 8 cm = 40 cm
6 parts = 6 × 8 cm = 48 cm
Then difference between lengths is 48 cm - 40 cm = 8 cm
longer piece is 8 cm longer than shortest piece.
Laura is going to invest in a business. There is a 50% chance that she will make $8000, a 40% chance that she will lose $4000, and a 10% chance that she will break even (make $0). What is the expected value for Laura's investment?
Answers
Based on the various probabilities of outcomes, the expected value of the investment is $2,400
The expected value can be calculated as:
= ∑ (Probability of event happening x Payoff if event happens)
The expected value here is therefore:
= (50% x 8,000) + (40% x -4,000) + (10% x 0)
= $2,400
In conclusion, the expected value is $2,400.

5 |2x + 6| = 25 what is x
Answers
Step-by-step explanation:
මාපාංක සුලු කිරිම.
l xl means ± x .
then |2x+6| = ±(2x+6)
for positive no;
5 (2x+6) = 25
10x + 30 = 25
10x = -5
x = -1/2
for negative no;
5(-2x - 6) = 25
-10x - 30 = 25
-10x = 55
x = - 11/2
otherthan that I observed.
5 |2x + 6| means only consider about the positive number. i think it called as amplitude.
then you have to calculate by considering only considering plus value.
