Evaluate the following when $a = 3$, $b = \frac14$, and $c = 5$: \[ \frac{b^{-1}}{ca^{-1} - ac^{-1}}. \] Thank you so much!
Answers
[tex]\dfrac{b^{-1}}{ca^{-1}-ac^{-1}}=\dfrac{\frac1b}{\frac ca-\frac ac}[/tex]
Multiply the numerator and denominator by [tex]ac[/tex]:
[tex]\dfrac{\frac1b}{\frac ca-\frac ac}\cdot\dfrac{ac}{ac}=\dfrac{\frac{ac}b}{c-a}[/tex]
Since [tex]b=\frac14[/tex], we have [tex]b^{-1}=\frac1b=4[/tex]. So substituting the values of a, b, and c gives us
[tex]\dfrac{\frac{ac}b}{c-a}=\dfrac{3\cdot5\cdot4}{5-3}=\dfrac{60}2=\boxed{30}[/tex]

To make 112 dozen muffins, a recipe uses 312 cups of flour.
How many cups of flour are needed for every dozen muffins made?
Enter your answer in the box as a mixed number in simplest form.
Answers
Answer:
Interesting question.
112/12 = 28/3
so 3/28 * 112 = 12
so we multiply 3/28 * 312
936/28
Simplifying we get 33 3/7
[tex]33 \frac{3}{7}[/tex] is the answer.
This is a mixed number with 2 as the whole part and 11/14 as the fractional part.
You may need to drop the ampersand sign and simply say 2 11/14
==============================================
Work Shown:
112 dozen muffins = 312 cups of flour
112/112 dozen muffins = 312/112 cups of flour
1 dozen muffins = 312/112 cups of flour
1 dozen muffins = (39*8)/(14*8) cups of flour
1 dozen muffins = 39/14 cups of flour
1 dozen muffins = (28+11)/14 cups of flour
1 dozen muffins = (28/14+11/14) cups of flour
1 dozen muffins = (2+11/14) cups of flour
1 dozen muffins = 2 & 11/14 cups of flour

Answers
Answer:
∠ABC≅∠DEF ∠BCA≅∠EFD ∠CAB≅∠FDE AB≅DE, BC≅EF, CA≅FDStep-by-step explanation:
To rotate point A 180° about the origin (point O) we draw a line from that point (A) throu the origin, measure the distance from the point A to the origin, and then measure the same distance on the other side of the origin to get rotated point. Mark it. The angle at the rotated point will be congruent to ∠A
The same goes for points B and C
Angles at pair of given and rotated point are congruent.
Sides of triangle are congruent if they lay between two congruent angles.

Answers
The vector notation <4, -5> is the same as writing [tex](x,y) \to (x+4, y-5)[/tex] which in my opinion is more descriptive in saying "4 units to the right, 5 units down"
We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.
The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.

How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
When we multiply numbers in scientific notation, then
1.466 x 5.02 =7.56932
Then we add the exponents on the powers of 10 as;
10^(-8+5) = 10^(-3)
The result is 7.56932 x 10^-3
Using a calculator, we get 0.00735932, this is not in scientific notation.
0.00735932 changed to scientific notation
Now Move the decimal until a nonzero digit is to the left of the decimal
7.35932
Which that means our exponent is -3
7.35932 x 10^-3

Now, what are the five factors of 16?
Type the factors in increasing order.
Answers
Given parameters:
The value given is 16
Problem is to find the factors of 16
A factor is any number that divides another number into equal parts without any remainder.
For 16, the factors are:
1 , 2 , 4 , 8 and 16
These numbers will divide 16 into equal parts. A number is a factor of itself.
1 is a factor of any number.
So, the five factors of 16 are 1, 2, 4, 8 and 16

Fill in the blanks concerning the following quadratic function: f(x)=−x2−4x+5
.
The leading coefficient of f(x)
is
Answers
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - 4x + 5
Leading term of the quadratic function is 'x²'
Coefficient of this leading term is (-1).
Now we will convert this standard equation into vertex form,
f(x) = -x² - 4x + 5
= -(x² + 4x) + 5
= -[x² + 2(2x) + 4 - 4] + 5
= -[x² + 2(2x) + 2²] + 4 + 5
= -(x + 2)²+ 9
f(x) = -(x + 2)² + 9
Since, coefficient of the leading term is negative the parabola will open downwards.
Vertex form of the function is given by,
g(x) = -(x - h)² + k
(h, k) is the vertex.
By comparing the equation of the function 'g' with the function 'f',
(-2, 9) will be the vertex of the function which is the maximum point of the function.

What is the equation in slope – intercept form? 7x + 2y = 14
Answers
Answer:
y = - [tex]\frac{7}{2}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y = 14 ( subtract 7x from both sides )
2y = - 7x + 14 ( divide all 3 terms by 2 )
y = - [tex]\frac{7}{2}[/tex] x + 7 ← in slope- intercept form

Here you are...
Step-by-step explanation:
If you double one of the dimensions, say change one side from 2 to 4 it doubles the volume. if you were to do this to any side, say double it, it would double the volume. ... It will make the volume 4 times as much also. the volume would go from 30 to 120.
