Answer:
80ab + 9b
Step-by-step explanation:
Step 1: 14 x 5 + 2ab x 5 + 4b x 2 + b
Then......
Multiple the numbers: 14 x 5 = 70
Step 2: = 70ab + 2 x 5ab + 4 x 2b + b
Then......
Multiple the numbers: 2 x 5 = 10
Step 3: = 70ab + 10ab + 4 x 2b + b
Then......
Multiple the numbers: 4 x 2 = 8
Step 4: = 70 ab + 10ab + 8b + b
Then......
Add similar elements: 70ab + 10ab = 80ab
Step 5: = 80ab + 8b + b
Then......
Add similar elements: 8b + b = 96
80ab + 9b

If a figure has elght vertices and 12 edges, how many faces does it have? 10
8
6
4
Answer:
It would have 6 faces
Step-by-step explanation:
In any convex polyhedron:
let v be the number vertices , e is the number of edges and f is the number of faces then;
....[1]
As per the statement:
If a figure has eight vertices and 12 edges
⇒v = 8 and e = 12
Substitute in [1] to solve for f, we have;
⇒
Subtract 6 from both sides we have;
f = 6

Step-by-step explanation:
The lateral area is formula for a cylinder is
[tex]2\pi \times r \times h[/tex]
where r is radius and h is height.
[tex]2\pi \times 8 \times 3 = 48\pi[/tex]
The surface area of cylinder is
[tex]2\pi \times {r}^{2} + 2\pi \times r \times h[/tex]
[tex]2\pi(64) + 2\pi(24)[/tex]
[tex]128\pi + 48\pi[/tex]
[tex]176\pi[/tex]
Volume of cylinder is
[tex]\pi \times {r}^{2} \times h[/tex]
[tex]\pi \times 64 \times 3[/tex]
[tex]192\pi[/tex]
Answer:
Step-by-step explanation:
Lateral area is the sides so for this it's distance around x 3 . b/c the cylinder is 3 units tall... sooo
r= radius , d= diameter
circumference = distance around = 2[tex]\pi[/tex]r or d[tex]\pi[/tex] = 16[tex]\pi[/tex]
Lateral area is 16[tex]\pi[/tex]*3 = 48[tex]\pi[/tex]
Surface area is the lateral area + the top and bottom
the area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
the area of this circle for the top is [tex]\pi[/tex][tex]8^{2}[/tex]
64[tex]\pi[/tex]
times 2 b/c there is also a top and a bottom
128[tex]\pi[/tex] + 48[tex]\pi[/tex] = 176[tex]\pi[/tex]
surface area is 176[tex]\pi[/tex] [tex]units^{2}[/tex]
Volume of a cylinder is area of the circle base times the height.
the base is 64[tex]\pi[/tex]
time 3 = 192[tex]\pi[/tex] [tex]units^{3}[/tex]
Volume is 603.1857 [tex]units^{3}[/tex]
note that two of the answer include pi, but you have that already put in for you in the answer so leave that part off.

(-1, -5) and (-1, -9)
(4, -7) and (2, -7)

What is the probability of the following
1. P (0< z < 1.46)?
Answer:
Approximately [tex]0.428[/tex].
Step-by-step explanation:
(This approach requires looking up values on a [tex]z[/tex]-table. Calculators aren't required.)
A typical [tex]z[/tex]-table lists probabilities in the form [tex]P(Z \le z)[/tex] (or equivalently, [tex]P(Z < z)[/tex],) where [tex]z\![/tex] is real number (typically greater than or equal to [tex]0[/tex].)
However, the question asks for a probability in the form [tex]P(a < Z < b)[/tex]. It would be necessary to rewrite this probability for this [tex]\!z[/tex]-table approach to work.
Let [tex]a[/tex] and [tex]b[/tex] denote two real numbers, with [tex]b > a[/tex]. [tex]P(a < Z < b)[/tex] would be equal to [tex]P(Z < b) - P(Z < a)[/tex]. In this question:
[tex]\begin{aligned} & P(0 < Z < 1.46) \\ & = P(Z < 1.46) - P(Z < 0) \end{aligned}[/tex].
Look up the value of [tex]P(Z < 1.46)[/tex] on a [tex]z[/tex]-table: [tex]P(Z < 1.46) \approx 0.927855[/tex].
On the other hand, [tex]P(Z < 0) = 0.5[/tex] because the Gaussian distribution is symmetric.
Therefore:
[tex]\begin{aligned} & P(0 < Z < 1.46) \\ & = P(Z < 1.46) - P(Z < 0) \\ &\approx 0.927855 - 0.5 \\ &\approx 0.428\end{aligned}[/tex].

An equilateral triangle has side length 8 units. What is the area?
A. 24√3 units
B. 24 units
C. 32 units
D. 16√3 units
Answer:
D. 16√3
Step-by-step explanation:
To find the area, you have to find the height. To find that, you spit the triangle in half for a 30 - 60 - 90 triangle and figure out that the height is 4√3.
After you find the height, you do the equation for the area of a triangle which is 1/2 side * height, and you fill it out.
1/2 8 * 4√3
4 * 4√3
16√3

Answer:
Slope, m = -8
Step-by-step explanation:
Given the following data;
Points on x-axis (x1, x2) = (2, 3)
Points on y-axis (y1, y2) = (5, -3)
To find the slope, m;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {-3 - 5}{3 - 2} [/tex]
[tex] Slope, m = \frac {-8}{1} [/tex]
Slope, m = -8/1
Slope, m = -8
If P = (3,2), find the image
of P under the following rotation.
270° counterclockwise about the origin
([?], [])
Given:
The point P = (3,2) is rotated 270° counterclockwise about the origin.
To find:
The image of the given point after rotation.
Solution:
If a point rotated 270° counterclockwise about the origin, then the rule of rotation is:
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex]P(3,2)\to P'(2,-3)[/tex]
Therefore, the image of given point P = (3,2) after the rotation of 270° counterclockwise about the origin, is P'(2,-3).

John has an annual salary of $48,000.00 and he is paid every two weeks. What will his
gross income be on each paycheck?
Answer: $1846
Step-by-step explanation:
First and foremost, we should note that there are 52 weeks in a year. Therefore the biweekly payment of John will be gotten by dividing his gross income by 26 weeks i.e (52weeks/2) since it's biweekly.
Therefore, the gross income on each paycheck will be:
= $48,000.00 / 26
= $1846.15
= $1846 approximately
The gross income on each paycheck is $1846.
someone please help me answer this
Answer:
a = 57 mm is the answer.
Step-by-step explanation:
a = ?
b = 76 mm
c = 95 mm
According to the Pythagoras theorem,
a² + b² = c²
a² + 76² = 95²
a² + 5776 = 9025
a² = 9025 - 5776
a² = 3249
a = 57 mm
∴ a = 57 mm is the length of the missing leg.
Answer:
57 mm
Step-by-step explanation:
To solve for a, we can use the Pythagorean Theorem.
a² + b² = c²
We have to solve for a, and we are given values for b and c, c being the hypotenuse.
This is what we know-
a² + 76² = 95²
We can simplify this to-
a² + 5776 = 9025
To solve for a, we have to isolate the variable on on side of the equals sign. So, we can subtract 5776 from both sides.
a² + 5776 - 5776 = 9025 - 5776
Simplify.
a² = 3249
Finally, to solve for a, find the square root of a².
[tex]\sqrt{3249^{2}[/tex] = 57
So, a = 57 mm
I hope this is helpful :) Good luck ^^

How will the appearance of the graph change if the a value in the function is decreased, but remains greater than 0
a) the graph will increase at a slower rate
b) the graph will show a decreasing, rather than increasing, function
c) the graph will show an initial value that is lower on the y-axis
d) the graph will increase at a constant additive rate, rather than a multiplicative rate
Answer:
C
Step-by-step explanation:
in exponential equations f(x)=ab^x , a is the intial amount while b is the growth factor. you are just decreasing a so the intial value is lower (=^w^=)
