Answer:
When rolling di.e #2, since we must roll a different odd number, the probability of doing so is 2/6 = 1/3. Thus, the probability is 1/2 x 1/3 = 1/6.
3) What is an equation for the line that passes through the coordinates (-1.2) and (7,6) ?
Answer:
[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]
Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.
[tex]\frac{6-2}{7- (-1)}=\frac{4}{8}=\frac{1}{2}[/tex]
So now we have the equation [tex]y=\frac{1}{2} x+b[/tex], and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation
[tex]2=\frac{1}{2}(-1)+b[/tex]
Rearrange the equation so it equals b
[tex]\frac{5}{2}=b[/tex]
Put it together and that's the final equation!
[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]

The indefinite integral can be found in more than one way. First use the substitution method to find the indefinite integral. Then find it without using substitution. Check that your answers are equivalent. 6x^5(x^6-2)dx
Answer:
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C[/tex]
Step-by-step explanation:
To find:
∫[tex]6x^5(x^6-2)\,dx[/tex]
Solution:
Method of substitution:
Let [tex]x^6-2=t[/tex]
Differentiate both sides with respect to [tex]t[/tex]
[tex]6x^5\,dx=dt[/tex]
[use [tex](x^n)'=nx^{n-1}[/tex]]
So,
∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫ [tex]t\,dt[/tex] = [tex]\frac{t^2}{2}+C_1[/tex] where [tex]C_1[/tex] is a variable.
(Use ∫[tex]t^n\,dt=\frac{t^{n+1} }{n+1}[/tex] )
Put [tex]t=x^6-2[/tex]
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1[/tex]
Use [tex](a-b)^2=a^2+b^2-2ab[/tex]
So,
∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1=\frac{1}{2}(x^{12}+4-4x^6)+C_1=\frac{x^{12} }{2}-2x^6+2+C_1=\frac{x^{12} }{2}-2x^6+C[/tex]
where [tex]C=2+C_1[/tex]
Without using substitution:
∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫[tex]6x^{11}-12x^5\,dx[/tex] = [tex]\frac{6x^{12} }{12}-\frac{12x^6}{6}+C=\frac{x^{12} }{2}-2x^6+C[/tex]
So, same answer is obtained in both the cases.

The length of a rectangle is 8 ft longer than twice the width. If the perimeter is 70 ft, find the length and width of the rectangle.
Answer:
9 ft and 26 ft
we will take as x the width, then
P rect. = 2(A+B)
A = 2x + 8 | 2×x, because there is b twice less, and + 8, because there is at 8 longer
B = x
70 = 2(2x + 8 + x)
70-16 = 4x + 2x
54= 6 x
54/6 = 9 => B = 9; A = 2×9+8 = 26

From a sample of 120 batteries, 3 are faulty. Work out the percentage of faulty
batteries.
Answer:
2.5%
Step-by-step explanation:
% = (faulty batteries / total batteries) x 100
= (3/120) x 100
= 0.025 x 100
= 2.5

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x
I need the equation of the parallel line asp
Answer:
y = 7x - 12
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m - > slope & b -> y-intercept
y = 7x
So, slope = 7 & (2 , 2)
y - y1 = m(x -x1)
y - 2 = 7(x - 2)
y - 2 = 7x - 14
y = 7x - 14 + 2
y = 7x - 12

Answer:
430 cm³
Step-by-step explanation:
= 11 × 10 × 2
= 220 cm³
= 10 × 3 × (9-2)
= 210 cm³
= 220 + 210
= 430 cm³
Answer:
430 cubic centimeters
Step-by-step explanation:
Lets start by separating both figures. Start with the one in the back, which is the bigger one.
Given:
Length = 10 cm
Width = 3 cm
Height = 9 cm
This is a rectangle and the volume of a rectangle is L x W x H. Therefore,
Volume = 10 x 3 x 9 = 270 cubic centimeters
Now we move on to the second figure.
Given:
Length = 10 cm (Given from the other rectangle)
Width = 8 cm (We do 11 - 3 since we separated the rectangles)
Height = 2 cm
Using the same formula we get the following.
Volume = 10 x 8 x 2 = 160 cubic centimeters
____
Finally, we add both volumes back since we separated the figures in the beginning.
Volume = 270 + 160 = 430 cubic centimeters

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at
590 mph.
Which equation is correctly written in standard form to represent this scenario?
0 590a - 550b = 1275
550a +590b = 1275
590a + 550b = 1275
550a - 5906 = 1275
Answer:
550a + 590b = 1275
Step-by-step explanation:
We use the following relation to solve this question:
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity, d is the distance and t is the speed.
In this question, we find the distance, so we use:
[tex]d = v*t[/tex]
A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
This means that [tex]d = 1275[/tex].
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.
This means that [tex]v*t = 550a + 590b[/tex].
Which equation is correctly written in standard form to represent this scenario?
[tex]d = v*t[/tex]
1275 = 550a + 590b
550a + 590b = 1275
Use the Pythagorean Theorem to find the length of the leg in the triangle shown below. 5, 13
Answer:
Leg= Leg- hypotenuse
Step-by-step explanation:
5 suquared= 25
13 squared= 169
25+169 =194
194 square root is 13.9
How to determine each side of a right triangle
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)
Answer:
13.9 (rounded)
Step-by-step explanation:
The pathaegorean theorem is A²+B²= C²
5²=25
13²= 169
169+25=194
√194=13.9
