Answer:
50%
Step-by-step explanation:
There are 32 total chips. Since there are 16 green and red chips, which is 1/2 of 32, the probability of getting a green or red chip is 50%.
Which graph represents this system? 2x-5v=-5 y=-3x+1
Answer:
Please check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the system of equations
2x - 5y = -5 --- [Equation 1]
y = -3x + 1 --- [Equation 2]
converting the equation 1 in the slope-intercept form
2x - 5y = -5
5y = 2x+5
divide both sides by 5
y = 2/5x + 1
Thus, the y-intercept = 1
Now, please check the attached graph below.
The red line represents the equation 2x - 5y = -5
From the graph, it is clear that the red line has the y-intercept y = 1.
Now, considerng the equation 2
y = -3x + 1
comparing with the slope-intercept form of line equation
The y-intercept b = 1
Hence, the y-intercept of the line y = -3x + 1 is y = 1
The green line represents the equation y = -3x + 1
From the graph, it is clear that the green line has the y-intercept y = 1.
Point of Intersection:
It is clear from the graph:
The red line represents the equation 2x - 5y = -5.The green line represents the equation y = -3x + 1.As both lines meet or intersect at the point (0, 1).
Therefore, the point of intersection of both the lines is:
(x, y) = (0, 1)
As we know that the point of intersection of both the lines represents the solution to the system of equations.
Therefore, (0, 1) on the graph represents the solution to the system of equations.
The graph is attached below.

Find the length of BC, in simplest radical form.
9514 1404 393
Answer:
BC = 16 +12√3
Step-by-step explanation:
In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.
EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.
The length BC is ...
BC = EC +BE
BC = 16 +12√3

Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regularly. However, her grandmother gave her the generous gift of $2500 for her birthday and suggested she invest it in a GIC because it’s low risk. She shopped around and found a 4 year GIC investment that earns 2.8% interest annually. How much will Anna have at the end of her four year investment?
Answer:
She will have $2792 at the end of her four year investment
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Gift of $2500:
This means that [tex]P = 2500[/tex]
She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.
This means that [tex]t = 4, r = 0.028, n = 1[/tex].
How much will Anna have at the end of her four year investment?
This is A(4). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(4) = 2500(1 + 0.028)^{4} = 2792[/tex]
She will have $2792 at the end of her four year investment

question 3, thanks for the help :)
Answer:
The slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3
Step-by-step explanation:
Given the points
(1, 2)(3, 8)Here:
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 8)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [8 - 2] / [3 - 1]
= 6 / 2
= 3
Thus, the slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3

Answer:
Negative 4
-4
Step-by-step explanation:
x+5= -23
-x+y= -1
6y= -24
-24÷6= -4
Answer:
Step-by-step explanation:
x + 5y = -23
5x - 5y = 5
6x = -18
x = -3
-3 + 5y = -23
5y = -20
y = -4

A painter is buying gallon containers of paint. He has $375 to spend and each gallon container costs $11.
How many gallon containers of paint can the painter buy?
PLZ HELP
Hey there!
35 containers of paint
We simply divide 375 by 11, and we get 34.09..., but since we can't buy .09 of a container of paint, we can only by 35 containers of paint.

Step-by-step explanation:
differentiate t²sin(2t)
Answer:
[tex]\displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]
Step-by-step explanation:
We are given a function:
[tex]\displaystyle \large{y = t^2 \sin (2t)}[/tex]
To differentiate a function, we are going to use the product rules since there are two functions which are t^2 and sin(2t) multiplying together.
From the product rules, [tex]\displaystyle \large{y = f(x)g(x) \to y\prime = f\prime (x) g(x)+f(x) g\prime (x)}[/tex]
Therefore, [tex]\displaystyle \large{y = t^2 \sin (2t) \to y\prime = (t^2)\prime \sin (2t) + t^2 (\sin (2t))\prime}[/tex]
Before we start differentiating, I’d like you to look at [sin(2t)]’. A function like this, you cannot just directly derive and answer. You need to use chain rules.
We know that, [tex]\displaystyle \large{y = \sin (x) \to y\prime = \cos (x)}[/tex] but what if the “x” is another function? Like sin(3x), sin(x^2) as examples. The insides are another function, can be expressed as fog(x) or gof(x) is composite function.
Basically, chain rule is a rule or formula for composite function and it’s the most common and useful as well as being always used in differentiation.
Chain Rules
[tex]\displaystyle \large{\frac{dy}{dx} = \frac{dy}{du} \frac{du}{dx}}[/tex]
where u is another function in a bracket. From the formula above, it can be also written as:
[tex]\displaystyle \large{[f(g(x))]\prime = f(g(x))\prime \cdot g(x)\prime[/tex]
To simply say, you differentiate the whole function first then multiply with the chain or inner derived function.
So from the function, we obtain:
[tex]\displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot (2t)\prime}\\ \displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot 2}\\ \displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]
The factored form would be:
[tex]\displaystyle \large{y\prime = 2t ( \sin (2t) + t \cos (2t))}[/tex]
From above, for polynomial function, to differentiate, you can do by using the power rules.
Power Rules
[tex]\displaystyle \large{y = ax^n \to y\prime = nax^{n-1}}[/tex]
