Answer:

It is the opposite of the shortest angle.!!!

Step-by-step explanation:

The solution to the system of equations is x = -3 and y = -4.

To solve the system of equations:

Equation 1: 2x - y = -10

Equation 2: 3x + 2y = -1

We can use the method of substitution or elimination to find the values of x and y.

Let's use the method of elimination:

Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(2x - y) = 2(-10)

4x - 2y = -20

Now, we can eliminate y by adding Equation 2 and the modified Equation 1:

(3x + 2y) + (4x - 2y) = -1 + (-20)

7x = -21

x = -3

Substitute the value of x into Equation 1 to solve for y:

2(-3) - y = -10

-6 - y = -10

y = -10 + 6

y = -4

Therefore, the solution to the system of equations is x = -3 and y = -4.

Answer:

The calf raiser uses 960 oz of milk replacer for 15 calves, so each calf gets 960 oz / 15 = 64 oz of milk replacer.

To convert this to quarts, we need to divide by 32 (since there are 32 oz in a quart)

64 oz / 32 oz/quart = 2 quarts

Each calf gets 2 quarts of milk replacer and the calf raiser needs to add 34 as much water as milk replacer

So the total amount of water she needs is 2*34 = 68 quarts

To convert the quarts of water to ounces we need to multiply by 32 (since there are 32 oz in a quart)

68 quarts * 32 oz/quart = 2176 oz of water.

So the calf raiser needs 2176 ounces of water to mix with the milk replacer for 15 calves.

Step-by-step explanation:

9+9+9+9 is 32 so thats your answer because all sides on a square are equal

Answer:

\(\boxed {\tt 36 \ centimeters}\)

Step-by-step explanation:

The perimeter is the sum of all the side lengths and a square has 4 equal sides.

The perimeter of a square can be found by adding the side length 4 times or multiplying the side length by 4.

\(p=4s\)

The side length is 9 centimeters.

\(s= 9 \ cm\)

Substitute the value into the formula.

\(p=4(9 \ cm)\)

Multiply

\(p= 36 \ cm\)

The perimeter of a square with a side length of 9 centimeter is 36 centimeters.

The shaded area under the curve is equal to 0.6826.

From the information provided, we have the following parameters:

Mean, μ = 501

Standard deviation, σ = 55.00

In this exercise, you are required the shaded area under the curve and this can be represented or modeled by this mathematical expression:

446 ≤ x ≤ 556

The lower limit (boundary) is equal to 446 i.e x₁ = 446.

The upper limit (boundary) is equal to 556 i.e x₂ = 556.

Next, we would determine the z-score for both limits as follows:

Z-score = (x₁ - μ)/σ

Z-score = (446 - 501)/55.00

Z-score = -55/55.00

Z-score = -1.00

For the upper limit, we have:

Z-score = (x₂ - μ)/σ

Z-score = (556 - 501)/55.00

Z-score = 55/55.00

Z-score = 1.00

By using a z-score calculator, the area is given by:

P(446 ≤ x ≤ 556) = P(-1.00 ≤ x ≤ 1.00)

P(-1.00 ≤ x ≤ 1.00) = P(x ≤ 1.00) - P(x ≤ -1.00)

P(-1.00 ≤ x ≤ 1.00) = 0.6826.

Step-by-step explanation:

The answer is 0.044

I hope you have a nice night/day

Using division of fraction, 0.011 ÷ 0.25  gives 0.044

For dividing two fractions we keep the first one as it is and replace the sign of division by multiplication and take the reciprocal of the second number .

For example if we want to divide (a/b) by (c/d)

Then we write its as (a/b) ÷(c/d) = (a/b) × (d/c)

Given that 0.011 is divided by 0.25

That is 0.011 ÷ 0.25

=  (11 / 1000)÷ (25/100)

=  (11 / 1000)÷ (1/4)

=   (11 / 1000) ×4

= (44/1000)

= 0.044

Therefore, 0.011 divided by 0.25 results into 0.044

The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.

This can be calculated using a rule of three as follows. Let's start with the yellow fish:

53 = 65

x    = 100

53 x 100 / 65 = 82 yellow fish

Green fish:

12 = 65

Domain:

The function to be used for answering questions is
\(f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1\)

a. Graph

Graph is plotted using online graphing tool. 2 points identified are (-4, 9) and (-3, 3)

b. Domain and Range

First let's understand what domain and range are

Definition of domain

The domain of a function, y = f(x),  is the set of input(x)  values for which the function is real and defined

The function has no undefined points nor domain constraints.  You can see that the graph goes to infinity for negative and positive x values Therefore,  the domain is :

\(-\infty \: < x < \infty \:\)

which can be expressed in interval notation as:

\(\left(-\infty \:,\:\infty \:\right)\)

Definition of range

The range of a function y = f(x) is the set of values for y over the domain for which the function is defined

As \(x \rightarrow \infty\), \(y \rightarrow 1\)

y never quite reaches 0 but its value approaches 1 and therefore the range is
\(f(x) > 1\\\\\)

In interval notation:
\(\left(1,\:\infty \:\right)\)

c. End Behavior

The end behavior of a function  f(x)  refers to how the function behaves when the variable x  increases or decreases without bound. In other words, the end behavior describes the ultimate trend in the graph of f(x) as \(x \rightarrow \pm \infty\)

In this particular function we see that as \(x\to \:+\infty \:,\:f\left(x\right)\to \:1\\\)

and as \(x\to \:-\infty \:,\:f\left(x\right)\to \:\infty\\\)

d. Point (-3, 3)
By pure chance I chose this point as one of the points asked for in part a because I was looking for integer values I don't think it matters that there is repetition

(-3, 3) is plotted on the graph as point A

3. Evaluate f(-3)
We have
\(f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1\)

To find f(-3) substitute -3 for x in the above function:

\(f(-3) = 8\left(\dfrac{1}{4}\right)^{-3+4}+1\\\\= 8\left(\dfrac{1}{4}\right)^1} + 1\\\\\\= 8\left(\dfrac{1}{4}\right) + 1\\\\= 2 + 1 \\\\= 3\)

So f(-3) = 3

Answer:

a)  See attachment 1.

b)  Domain: (-∞, ∞)

     Range: (1, ∞)

c)  As x → -∞, f(x) → ∞

    As x → ∞, f(x) → 1⁺

d)  See attachment 2.

e)  See below.

Step-by-step explanation:

Given exponential function:

\(f(x)=8\left(\dfrac{1}{4}\right)^{x+4}+1\)

To find the y-intercept, input x = 0 and solve for y:

\(\implies f(0)=8\left(\dfrac{1}{4}\right)^{0+4}+1\)

\(\implies f(0)=8\left(\dfrac{1}{4}\right)^{4}+1\)

\(\implies f(0)=8\left(\dfrac{1}{256}\right)+1\)

\(\implies f(0)=\dfrac{1}{32}+1\)

\(\implies f(0)=\dfrac{33}{32}\)

\(\implies f(0)=1.03125\)

Therefore, the y-intercept is (0, 1.03125).

Substitute x = -2 into the function to find a second point on the curve:

\(\implies f(-2)=8\left(\dfrac{1}{4}\right)^{-2+4}+1\)

\(\implies f(-2)=8\left(\dfrac{1}{4}\right)^{2}+1\)

\(\implies f(-2)=8\left(\dfrac{1}{16}\right)+1\)

\(\implies f(-2)=\dfrac{1}{2}+1\)

\(\implies f(-2)=\dfrac{3}{2}\)

\(\implies f(-2)=1.5\)

Therefore, a second point on the curve is (-2, 1.5).

The domain of a function is the set of all possible input values (x-values).  

The domain of the given function is unrestricted:

The range of a function is the set of all possible output values (y-values).

As the exponential part of the function is always positive, the range of the given function is restricted:

As x approaches negative infinity, the function approaches positive infinity:

As x approaches positive infinity, the function approaches f(x) = 1.

See attachment 2.

Substitute x = -3 into the function:

\(\implies f(-3)=8\left(\dfrac{1}{4}\right)^{-3+4}+1\)

\(\implies f(-3)=8\left(\dfrac{1}{4}\right)^{1}+1\)

\(\implies f(-3)=8\left(\dfrac{1}{4}\right)+1\)

\(\implies f(-3)=2+1\)

\(\implies f(-3)=3\)
