Answer:
No, Each input has one output
Step-by-step explanation:
A circle can't be a function because of its radius and diameter, its not linear so it might have the same input or output. Therefore, you need a line to have a linear function .!

A line passes through point (-10, – 4) and has a slope of -3/2
Write an equation in Ax+By=C form for this line.
Use integers for A, B, and C.
9514 1404 393
Answer:
3x +2y = -38
Step-by-step explanation:
When a point and the slope are given for a line, the point-slope form of the equation is useful.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -(-4) = -3/2(x -(-10))
y + 4 = -3/2x -15
Multiplying by 2 gives ...
2y +8 = -3x -30
Adding 3x-8, we get ...
3x +2y = -38
Answer:
3x + 2y = -38
Just plug in the x and y values to get the answer!
We already know that when x is -10 y = -4 so all we have to do is substitute them.
y = mx + b
-4 = -3/2(-10) + b
-4 = 30/2 + b
-4 = 15 + b
-19 = b
Maria ha acquistato un libro, scontato del 15%, al prezzo di 34 euro. Dopo avere letto 1/4 delle pagine del libro. Legge 2/3 delle pagine rimanenti e a questo punto le restano da leggere 104 pagine. Determina:
Il prezzo del libro prima dello sconto
Il numero di pagine complessive del libro
La percentuale che rappresenta il numero di pagine che restano da leggere a Maria rispetto al numero di pagine complessivo.
Answer:
a) 40 euros
b) 416 pages
c) 25%
Step-by-step explanation:
This question can be translated to:
Maria bought a book, discounted by 15%, at the price of 34 euros. After reading 1/4 of the pages of the book. She reads 2/3 of the remaining pages and at this point, she has 104 pages left to read. Determine:
a) The price of the book before the discount
b) The total number of pages in the book
c) The percentage that represents the number of pages that Maria has left to read out of the total number of pages.
I will answer in English.
a) If P is the price of the book, with a discount of the 15% the price will be:
P' = P - P*(15%/100%) = P - P*0.15 = P*0.85
and P' = 34 eur
34 eur = P*0.85
34 eur/0.85 = 40 eur = P
The original price was 40 euros.
b) Now suppose that the book has N pages.
First, she reads 1/4 of the pages, then we have:
N - (1/4)*N = (3/4)*N pages left.
Then she reads (2/3) of the remaining (3/4)*N pages.
Then there are:
(3/4)*N - (2/3)*(3/4)*N = (1/3)*(3/4)*N = (1/4)*N
And we know that at this point, there are 104 pages left, then:
104 = (1/4)*N
104*4 = N = 416
c) The total number of pages is 416, this is the 100%
there are 104 pages left in the book, this will represent X%, and we want to find the value of X.
then:
416 = 100%
104 = X%
Let's take the quotient of those two equations:
(416)/(104) = (100%/X%)
Now let's isolate X%.
X% = (104/416)*100% = 0.25*100% = 25%
A flagpole at a right angle to the horizontal is located on a slope that makes an angle of \large 10^\circ with the horizontal. The flagpole casts a 30-meter shadow down the slope. The angle of elevation from the tip of the shadow to the sun is \large 25^\circ. What is the length of the flagpole to the nearest tenth of a meter?
Answer:
13.1 m
Step-by-step explanation:
From the diagram attached :
Using Sine rule :
a / sin A = b/Sin B = c / sin C
h / sin 25 = 30 / sin 75
Cross multiply :
h * sin 75 = 30 * sin 25
0.9659258 * h = 30 * 0.4226182
h = 12.678547 / 0.9659258
h = 13.125798
Length of flagpole h = 13.1 m

Which Number Represents the expression - 2 + ( - 7/2) ?
Answer:

i hope this helps <3
Answer:
[tex]-\frac{11}{2}[/tex] is the number which represents the expression [tex]-2+\left(\frac{-7}{2}\right)[/tex].
i.e.
[tex]-2+\left(\frac{-7}{2}\right)=-\frac{11}{2}[/tex]
Step-by-step explanation:
Given the expression
[tex]-2+\left(\frac{-7}{2}\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]
[tex]=-2+\frac{-7}{2}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-2-\frac{7}{2}[/tex]
[tex]\mathrm{Convert\:element\:to\:fraction}:\quad \:2=\frac{2\cdot \:2}{2}[/tex]
[tex]=-\frac{2\cdot \:2}{2}-\frac{7}{2}[/tex]
[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=-\frac{2\cdot \:2}{2}-\frac{7}{2}[/tex]
[tex]=\frac{-2\cdot \:2-7}{2}[/tex]
[tex]=\frac{-11}{2}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{11}{2}[/tex]
Therefore, [tex]-\frac{11}{2}[/tex] is the number which represents the expression [tex]-2+\left(\frac{-7}{2}\right)[/tex].
i.e.
[tex]-2+\left(\frac{-7}{2}\right)=-\frac{11}{2}[/tex]

You bake cookies for a bake sale. The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5. You bake 15 oatmeal cookies. How many chocolate chip cookies do you bake?
Answer:
21
Step-by-step explanation:
[tex]\frac{7}{5}[/tex] = [tex]\frac{x}{15}[/tex]
x = 21 chocolate chip cookies.
There are 21 chocolate chip cookies do you bake.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
Given that;
The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5.
And, You bake 15 oatmeal cookies.
Now,
Since, The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5.
Hence, The amount of chocolate chips = 7x
And, The amount of oatmeal cookies = 5x
Here, You bake 15 oatmeal cookies.
Hence, We get;
The amount of oatmeal cookies = 5x = 15
So, we get;
⇒ 5x = 15
⇒ x = 3
So, The amount of chocolate chips = 7x
= 7 × 3
= 21
Thus, There are 21 chocolate chip cookies do you bake.

To aid in sea navigation, Little Gull Island Lighthouse shines a light from a height of 91 feet above sea level with an unknown angle of depression. If the beam of light shines on the sea surface at a point that is 865 feet away from the base of the lighthouse, what is the angle of depression?
Answer:
[tex]\approx 6^\circ[/tex]
Step-by-step explanation:
Given that:
Little Gull Island Lighthouse shines a light from a height of 91 feet above the sea level.
The angle of depression is unknown.
Distance of the point at sea surface from the base of lighthouse is 865 ft.
This situation can be modeled or can be represented as the figure attached in the answer area.
The situation can be represented by a right angled [tex]\triangle ABC[/tex] in which we are given the base and the height of the triangle.
And we have to find the value of [tex]\angle BAD \ or \ \angle C[/tex] (Because they are the internal vertically opposite angles).
Using tangent ratio:
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tanC = \dfrac{AC}{BC}\\\Rightarrow tanC = \dfrac{91}{865}\\\Rightarrow tanC = 0.105\\\Rightarrow \angle C \approx 6^\circ[/tex]
Therefore, the angle of depression is: [tex]\approx 6^\circ[/tex]
A baker at a bakery had made 20 pastries after 1 hour of work. After 8 hours, he had made 83 pastries. M= ?
9514 1404 393
Answer:

Step-by-step explanation:
In the 7 hours after the first, the baker made 83 -20 = 63 more pastries. That rate is ...
(63 pastries)/(7 hours) = 9 pastries per hour

Additional comment
We have chosen to interpret the question as asking for the slope of a line on a graph of pastries vs. hours. Such a graph would show you the baker started with 11 pastries already made, so didn't actually make 20 in the first hour.

x² = 30² +21² -2(30)(21) Cos 123°
Answer:
x ≈ 44.69
Step-by-step explanation:
x² = 30² +21² -2(30)(21)Cos123°
x² = 900 + 411 - 1260cos123°
x² = 1311 - 1260cos123²

Answer:
The answer is 88%
Step-by-step explanation:
To find a percentage, just divide the top number by the bottom. 22 divided by 25 is 0.88 which means 22 out of 25 is 88%.
Another way to do it is to multiply both 22 and 25 by 4. The denominator will now equal 100 so now the top number will be the percentage. 22*4 is also 88.
Hope this helped.
