Answer:
diameter: 3.31 mm
Explanation:
circumference of circle → πd
using the formula:
10.4 = πd
d = 10.4/π
d = 3.31 mm
Answer:
diameter = 3.31 mm (3 sf)
Step-by-step explanation:
Diameter of a circle (d) = 2r (where r is the radius)Circumference of a circle = 2[tex]\pi[/tex]r (where r is the radius)Given:
circumference = 10.4 mm⇒ [tex]\pi[/tex]d = 10.4
⇒ d = 10.4 ÷ [tex]\pi[/tex] = 3.31 mm (3 sf)

A church auditorium can seat 250 people at most. If there are currently 162 people seated in the auditorium, how many more can be seated? Write an inequality then solve it. Use n for your variable. Can someone please help I'm really stuck.
Answer:
88 more people
Step-by-step explanation:
Let the additional number of people that can be seated be n.
Maximum capacity of auditorium= 250
This means that the amount of people in the auditorium can be exactly 250 or less than that. Thus, the inequality sign used is '≤', which can be read as 'less than or equal to'.
Since there are already 162 people in the auditorium,
162 +n ≤ 250
Subtract 162 from both sides:
n ≤ 250 -162
n ≤ 88
Thus, 88 more people can be seated.
Note:
An equation with an inequality symbol is solved the same way as one with an equal sign, except when dividing both sides of the equation by a negative number (i.e. a number lesser than zero). In that case, the direction of the inequality sign will change:
• > becomes < and vice versa
• ≥ becomes ≤ and vice versa

1) Provide one example of a technology or communication system that allows information to be transferred for each of these three transfer methods: human to machine; machine to human; and machine to machine. Briefly describe each of the three technologies
When you think of an electronic log book for workplaces they are like this. human to machine- The human is speaking to the machine through actions of logging in times etc. Machine to human- The machine will now send a response to the human saying that it is logged. Machine to Machine- The machine will use its software to dispose or disclose the information you have given it.

Gary gets a bonus $20 for every computer he sells over and above his quota of 10 per week. If he
sells n computers in a week and n > 10 , write an expression for Gary’s bonus in that week
(in expanded form).
Answer:
The inequality that describes this problem is , and the minimum number of computers he must sell is 25.
Step-by-step explanation:
Since there is no restriction on the number of computers he must sell, an inequality can help us describe the situation.
Writing the inequality.
Let x be the number of computers he sells the next month, since he receives a bonus of $100 per computer he sells the total amount he will make for x computers is
And since he wants to make $2,500 in bonuses, the inequality that describes that situation is
Solving the inequality.
In order to find the exact number of computers he must sell, we need to solve for the inequality.
Since 100 is multiplying to x, in order to move that 100 to the other side, we need to apply the inverse operation to multiplication, which is division. We can then divide both sides by 100
So then we can simplify to get
Thus the minimum number of computers he must sell is 25.
M/4 - 2=6 evaluate expression
Answer: M = 32
Step-by-step explanation:
We can add 2 to each side of the equation to get M/4 = 8.
We can then multiply each side of the equation by 4 to get M = 32.

Step-by-step explanation:
Determine the simple interest. (The rate is an annual rate unless otherwise stated. Assume 360 days in one year.)
p= $375, r = 9.5%, t = 60 days
The simple interest is $ ____
(Round to the nearest cent as needed.)
if there are 360 days in 1 year, then 60 days is 60/360 = 1/6 of a year.
[tex]~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$375\\ r=rate\to 9.5\%\to \frac{9.5}{100}\dotfill &0.095\\ t=years\dotfill &\frac{1}{6} \end{cases} \\\\\\ I=(375)(0.095)(\frac{1}{6})\implies I\approx 5.94[/tex]

simplify the expression: (2y + 1)(5)
Answer:
10y+5
Step-by-step explanation:
5 x 2y = 10y
5 x 1 = 5
Answer:
10y + 5
Step-by-step explanation:
Expand the expression!
(2y + 1) * 5 : We have to multiply each factor by 5
2y * 5 = 10y
1 * 5 = 5
Combine those values, and we get 10y + 5 :)

Find the equation of the line passing through point (1,-5) and perpendicular to y=1/8x+2
Answer:
y=8x-13
Step-by-step explanation:
When you're finding a perpendicular line, you take the opposite of the slope. The slope in this equation is 1/8, so a perpendicular line will have the slope of 8. So we already know y=8x+b.
Plug in your x and y values from the ordered pair and you get -5=8(1)+b. 8×1 is just 8, so it's -5=8+b. Subtract 8 from both sides and you get -13=b.

2x - x = 35 subtract
x = 35
Measure
2x = 70 and
x + 35 = 70

Problem 2: Solve the initial value problem
[tex]y' = xy[/tex]
[tex]y(0) = 1[/tex]
Separate the variables:
y' = dy/dx = xy ⇒ 1/y dy = x dx
Integrate both sides:
∫ 1/y dy = ∫ x dx
ln|y| = 1/2 x² + C
Given that y(0) = 1, we have
ln|1| = 1/2 • 0² + C ⇒ C = 0
so that the particular solution is
ln|y| = 1/2 x²
Solving for y gives
y = exp(1/2 x²)
150% of what number is 120
Answer:
x = 80
Step-by-step explanation:
We have, 150% · x = 120
or, 150/100 · x = 120
Multiplying both sides by 100 and dividing both sides by 150,
we have x = 120 · 100/150
x = 80
If you are using a calculator, simply enter 120×100÷150, which will give you the answer.
[RevyBreeze]
Answer:80
Step-by-step explanation:
we have,
150x/100 = 120
x = 120 x 150/100
x= 80

find the equation of the tangent line to f(x)=6/x at x=-2
Answer:
[tex]\displaystyle \large{y = - \frac{3}{2}x}[/tex]
Step-by-step explanation:
Hey there! To find a tangent line of curve at specific point, we have to differentiate a given function. This is because a tangent line has same slope as the specific point and slope is equivalent to dy/dx.
From a given function, we can write as [tex]\displaystyle \large{f(x) = 6x^{-1}}[/tex] via law of exponent where [tex]\displaystyle \large{a^{-n}=\frac{1}{a^n}}[/tex] .
Then differentiate with respect to x using power rules.
Power Rules
For every differentiatable continuous functions, if [tex]\displaystyle \large{f(u) = u^n \to f\prime (u) = nu^{n-1} \cdot u\prime}[/tex] for u is any function and n is all real number.
Therefore:-
[tex]\displaystyle \large{f(x) = 6x^{-1}}\\\displaystyle \large{f\prime(x) = (-1)(6)x^{-1-1} \cdot x\prime}\\\displaystyle \large{f\prime(x) = -6x^{-2} }[/tex]
Therefore, our derived function is [tex]\displaystyle \large{f\prime(x) =- 6x^{-2}}[/tex]
Then substitute x = -2 in a derived function or slope.
[tex]\displaystyle \large{f\prime(-2) = -6x^{-2}}\\\displaystyle \large{f\prime(-2) = -6(-2)^{-2}}\\\displaystyle \large{f\prime(-2) = -6 \cdot \frac{1}{(-2)^2}}\\\displaystyle \large{f\prime(-2) = -\frac{6}{4}}\\\displaystyle \large{f\prime(-2) = -\frac{3}{2}}[/tex]
Therefore, the slope at x = -2 is -3/2.
Now we have to use point-slope formula to find the equation of tangent line.
Point-Slope
[tex]\displaystyle \large{y-y_1 = m(x-x_1) \to y-f(x_1) = f\prime (x_1)(x-x_1)}[/tex]
We may have to find the (x,f(x)) coordinate first. We know x = -2 but we don’t know f(x) coordinate at x = -2 yet. We substitute x = -2 in f(x) to find f(-2).
[tex]\displaystyle \large{f(-2) = \frac{6}{-2}}\\\displaystyle \large{f(-2) = -3}[/tex]
Therefore, our coordinate is (-2,-3).
Substitute in point-slope form.
[tex]\displaystyle \large{y-(-3)=-\frac{3}{2}(x-(-2))}\\\displaystyle \large{y+3=-\frac{3}{2}(x+2)}[/tex]
Then convert to slope-intercept form by isolating y-term and simplify the expression.
[tex]\displaystyle \large{y = - \frac{3}{2}(x+2)+3}\\\displaystyle \large{y = - \frac{3}{2}x-3+3}\\\displaystyle \large{y = - \frac{3}{2}x}[/tex]
Therefore, the equation of tangent line is y = -3x/2.
