Answer:
She baked 640 cookies at first.
Step-by-step explanation:
Let cookies be x and muffins be y,
Let cookies remaining be z and remaining muffins be a
x = 264 + y
now,
x - 3/8 of x = z
x - 3x/8 = z
or, (8x-3x)/8 = z
so, z = 5x/8
Now,
y - y/2 = a
or, (2y-y)/2 = a
so, a = y/2
Now,
z + a = 588
or, 5x/8 + y/2 = 588
as we know x = 264 + y,
or, 5(264 + y)/8 + y/2 = 588
or, (1320 + 5y)/ 8 + y/2 = 588
or, (2640 + 10y + 8y)/16 = 588
or, 2640 + 18y = 9408
or, 18y = 9408 - 2640
or, 18y = 6768
so, y = 6768/18
so, y = 376
now,
x = 264 + y
or, x = 264 + 376
so, x = 640

(−5,4)? Write your answer in simplest form.
Step-by-step explanation:
Slope formula:
[tex] \frac{y2}{x2} - \frac{y1}{x1} = m[/tex]
Substitute the points into the formula format:
[tex] \frac{4}{ - 5} - \frac{8}{ - 5} = m[/tex]
Solve:
[tex] \frac{ - 4}{0} = m[/tex]
When a slope has a run (x) of 0, the slope is undefined.
Answer:
-4 / 0
Step-by-step explanation:
Given the following question:
(-5, 8), (-5, 4)
In order to find the answer to this question we will use rise over run, substitute the values, and then solve.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
(-5, 8), (x1, y1)
(-5, 4), (x2, y2)
4 - 8 = -4
-5 - -5 = 0
m = -4 / 0
Hope this helps.
Please help for this question what is the function and thanks
Answer:
b) local minimum at [tex]x=\frac{1}{e}[/tex]
c) Graph of the function is convex
Step-by-step explanation:
We are told that [tex]f'(\frac{1}{e})=0[/tex], which implies there is a turning/stationary point at [tex]x=\frac{1}{e}[/tex].
Substituting [tex]x=\frac{1}{e}[/tex] into [tex]f''(x)[/tex] will tell us if the turning point is a minimum or a maximum:
[tex]f''(\frac{1}{e})=\frac{1}{\frac{1}{e} } =e>0 \implies \textsf{local minimum}[/tex]
Therefore, statement a) is false and statement b) is true.
If the function has a minimum turning point, then this implies that the curve is convex. Therefore, statement c) is true.
Extremum = local min and max points.
We have already established that there is a local minimum at [tex]x=\frac{1}{e}[/tex], therefore statement d) is false.
I know this is not needed for this question, but here are the workings to detemine the equation of the function (I've also attached a graph). This supports the answers above.
[tex]\textsf{if} \ f''(x)=\frac{1}{x}\\\\\implies f'(x)=\int f''(x) \ dx \\\\\implies f'(x)=ln|x|+C\\[/tex]
[tex]\textsf{if} \ f'(\frac{1}{e})=0\\\\\implies ln|\frac{1}{e}|+C=0\\\\\implies -1+C=0\\\\\implies C=1\\\\[/tex]
[tex]\implies f'(x)=ln|x|+1\\[/tex]
[tex]\textsf{if} \ f'(x)=ln|x|+1\\\\\implies f(x)=\int f'(x) \ dx\\\\\implies f(x)=xln(x)-x+x+C\\\\\implies f(x)=xln(x)+C[/tex]
Becky's brother has an investment account that he says earns an
average of 13% each year. If this is the case, approximately how long
will it take him to double his money?
Answer:
Approximately 8 yearsStep-by-step explanation:

[tex] \frac{13}{5} + \frac{13}{10} - \frac{47}{15} [/tex]
LCM of 5,10,15=30.[tex] = \frac{13 \times 6 + 13 \times 3 - 47 \times 2}{30} [/tex]

Are they similar or why are they not
Answer:
Yes they are similar due to the parallel lines of XY & BC. So, technically, the small and big triangle both will share the same base angles because corresponding angles are equal. Thus, angle AYX will be equal to angle YCB, for example.
In addition, two shapes are similar if one is an enlargement of another.

Find the area of the composite figure.
So in fig 1 :

L = 7mW = 16 - 9 = 7mArea= L × WArea = 7 × 7Area =49m² TA = 126 + 49TA = 175 m²The area of the composite figure is,
A = 175 m²
We have to given that,
A composite figure is shown.
In first part,
Lenght (L) = 14m
Width (W) = 9m
Hence, We get;
Area = L × W
Area = 9 × 14
Area = 126 m²
For second part,
Lenght (L) = 7m
Width (w) = 16 - 9 = 7m
Hence, We get;
Area= L × W
Area = 7 × 7
Area =49m²
So, We can formulate;
The area of the composite figure is,
A = 126 + 49
A = 175 m²

why is it important to convert your equation from standard form to slope intercept? How can this help you graph your equation?
Answer:
The slope intercept form is used to find the y-intercept and the slope of a straight line. If you look closely, it is a linear function too; meaning the function can tell you its domain and range.
