4 medium and 6 large.

Step-by-step explanation:

A possible answer to this is

10 pizzas, 66 slices.

the sum of slices needs to be 66 and canot exceed 10 pizzas in total.

6x4=24 slices

8x6=42 slices

4+6= 10 so it does not exceed 10 pizzas.

24 +42= 66 so there are 66 slices.

Answer:

Vectors are usually described in terms of their components in a coordinate system. Even in everyday life we naturally invoke the concept of orthogonal projections in a rectangular coordinate system. For example, if you ask someone for directions to a particular location, you will more likely be told to go 40 km east and 30 km north than 50 km in the direction 37° north of east.

In a rectangular (Cartesian) xy-coordinate system in a plane, a point in a plane is described by a pair of coordinates (x, y). In a similar fashion, a vector

A

in a plane is described by a pair of its vector coordinates. The x-coordinate of vector

A

is called its x-component and the y-coordinate of vector

→

A

is called its y-component. The vector x-component is a vector denoted by

x. The vector y-component is a vector denoted by

y. In the Cartesian system, the x and y vector components of a vector are the orthogonal projections of this vector onto the x– and y-axes, respectively. In this way, following the parallelogram rule for vector addition, each vector on a Cartesian plane can be expressed as the vector sum of its vector components:

approximately 85 m

Step-by-step explanation:

use the law of cosines

x²=120²+90²-2(120)(90)cos(45)

*120 & 90 are given values

*45 is from 25+20; bcuz of alternate interior angles, the other angle from mirror 1 is 25 degrees, making the total 45 degrees

x=√120²+90²-2(120)(90)cos(45)

x=85, the distance btwn origin point and mirror 2

Mathematical operators are essential tools for expressing mathematical ideas and solving problems in a concise and precise manner. The following parts can be solved the concept of Mathematical operators.

a) Let P(x) be the predicate "x is a negative real number" and Q(x) be the predicate "x is positive". Then the statement "the product of two negative real numbers is positive" can be expressed as:

∀x . ∀y[(P(x) ∧ P(y)) → Q(x . y)]

which reads "For all x and y, if x and y are negative real numbers, then the product of x and y is positive."

b) Let R(x) be the predicate "x is a real number". Then the statement "the difference of a real number and itself is zero" can be expressed as:

∀x[R(x) → (x - x = 0)]

which reads "For all x, if x is a real number, then the difference between x and x is zero."

c) Let S(x) be the predicate "x is a positive real number", and T(x, y) be the predicate "y is a square root of x". Then the statement "every positive real number has exactly two square roots" can be expressed as:

∀x[S(x) → ((∃y(T(x, y) ∧ ∀z(T(x, z) → z=y))) ∧ (∃y. ∃z(T(x, y) ∧ T(x, z) ∧ y ≠ z)))]

which reads "For all x, if x is a positive real number, then there exist exactly two distinct real numbers y and z such that y and z are square roots of x."

d) Let U(x) be the predicate "x is a negative real number", and V(x) be the predicate "x does not have a real square root". Then the statement "a negative real number does not have a square root that is a real number" can be expressed as:

∀x[U(x) → V(x)]

which reads "For all x, if x is a negative real number, then x does not have a real square root.

Answer:

11+11= 22 answer is $ 22.03

Answer:

Your answer would be:

D = 53 d.

First off notice how the top left and bottom right angels are obtuse angels (larger than 90 degrees). The top right and bottom left angels are acute (less than 90 degrees).

We will focus on the acute angels to finger out the problem. The value D that we are trying out must add to 26 degrees to equal the value of the other cute angle, 79 degrees (top right corner).

We can solve with the following equations:

26 degrees + D degrees = 79 degrees

79 d. - 26 d. = D d(egrees)

Summary:

79 d. - 26 d. = 53 d.

In conclusion, the value of angel D would equal 53 degrees.

D = 53 degrees

Answer:

D. 70.53

Step-by-step explanation:

To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:

\(sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\)

In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.

\(cos(\theta)=\frac{adjacent}{hypotenuse}\)

Substitute,

\(cos(CBA) = \frac{3}{9}\)

Simplify

\(cos(CBA) = \frac{1}{3}\)

Inverse operations,

\(CBA=cos^-1(\frac{1}{3})\)

Compute,

m<CBA = 70.53

The correct value for the upper control limit (ucl) for the corresponding control chart for the informations contained in table is equals to the 706.232.

We have a chart table present in above figure and shows the sample informations for making a control chart. Now, control Limits are Calculated by:

For a Sample size, n = 10

Average = 705

Range, R = 4

Formula for calculating upper control limit, UCL= Average + mean factor(A) × range (R), here, x and R are known. The value of A is corresponding value of sample size in the table. The sample size here is 10. Therefore value of A is 0.308. So, UCL = 705 + 0.308(4)

= 706.232

Similarly, LCL = Average - mean factor(A) × range (R)

=> LCL = 705 - 0.308(4)

= 703.778

In case 3-sigma control chart, the Upper control limit is calculated as, Average +3σ

Lower control limit= Average - 3σ. Hence, required value is equals to 706.232 .

The value of the line integral ∫Cxe^{yz}ds is approximately  8.645×10⁻⁵.

Given the line integral ∫Cxe^{yz}ds, where C is the curve r(t) = (t, 2t, -4t) for 1 ≤ t ≤ 2.

To convert this line integral to an ordinary integral with respect to the parameter, we need to express the integrand xe^{yz} in terms of the parameter t. We can do this by substituting r(t) into the integrand, giving us

te^{(2t)(-4t)}

= te^{-8t²}

Next, we can use the change of variable formula: ∫Cxe^{yz}ds = ∫[1,2]xe^{yz}||r'(t)||dt

We know that r'(t) = (1, 2, -4), so

||r'(t)|| = √(1² + 2² + (-4)²)

= √(17)

So the new integral becomes ∫[1,2] √(17)te^{-8t²} dt

On calculating ∫[1,2] √(17)te^{-8t²} dt ≈ 8.645×10⁻⁵

We have to find what are the domain and range of the function f of x is equal to the quantity x squared plus 6x plus 8 end quantity ÷ by the quantity x + 4 end quantity.

We know that,

If a rational function is defined as R(x)=p(x)/q(x), then the domain of the rational function is the intersection of domains of p(x) and q(x) except those values for which q(x)=0.

The given rational function is

f(x)=x²+6x+8/x+4

We need find the domain of the given function.

Here, both the numerator and the denominator are polynomial functions, and the range of a polynomial function is the entire real number range.

So, domain of the given function is all real number except those values of x for which x+4=0.

x+4=0

x=-4

Domain of f(x) = All real numbers except -4.

Domain of f(x) = (−∞, -4)∪(-4, ∞)

The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.

A. No solution

y = 1/4x+5

x - 4y = 4

You can simplify the second equation into y = 1/4x - 1

Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.

Answer:

The reason why it isnt true is because you cannot combine exponents that have different bases.

Step-by-step explanation:

So, with the problem shown below, it is \(3^5*2^4\)

This cannot be multiplied.

To get \(6^9\), you would need 6^4*6^5

So basically, its like ths:

If two exponents have to same base, they can be added together. THis adds the exponents, but leaves the bases the same.

If two exponents have different bases, they cannot be added together. You would have to distrubute both the numbers exponents then multiply them together.

For instance, with \(3^5*2^4\), you would have to make it 243+16

This would equal 259.

As we can see, \(6^9\) is over 10 million, much bigger than this.

Answer:

Step-by-step explanation:

Imagine the numbers are plotted on the number line.

Order on the number line which is from least to greatest:

The actuarial present value of a temporary life annuity-immediate can be calculated using the life table and an assumed interest rate. In this case, the annuity is for a person aged 30 and has 20 certain payments. We are also given that the annuity will not make more than 40 payments and that mortality follows the Standard Ultimate Life Table. The interest rate is given as 0.05 (or 5%).

To determine the actuarial present value, we need to calculate the present value of each payment and sum them up. The present value of each payment is calculated by multiplying the payment amount by the present value factor, which is derived from the life table and the interest rate. The present value factor represents the present value of receiving a payment at each age, considering the probability of survival.

The detailed calculation requires specific mortality and interest rate tables, as well as formulas for present value factors. Without this information, it is not possible to provide a specific answer. I recommend consulting actuarial resources or using actuarial software to perform the calculation accurately.
