Answer: The answer is 0 (An undefined slope)

Step-by-step explanation: The answer would be 0 but you can not just use 0 you have to use math terms. So in math terms undefined slope is o. ALSO if the line is Horizontal its o and if the line is Vertical it is undefined.

NOTE: 0 AND UNDEFINED iS NOT THE SAME THING

Answer:

[tex]1.9[/tex]

the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Step-by-step explanation:

The function is

[tex]f(t)=1.9+1.4t[/tex]

Let cost of toppings be [tex]y[/tex]

[tex]y=1.9+1.4t[/tex]

The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].

So, the intercept of the function is [tex]1.9[/tex]

This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Answer:

The expression is a fourth grade trinomial.

Step-by-step explanation:

Mathematically speaking, a polynomial is an equation of the form:

[tex]y = \Sigma_{i = 0}^{n} c_{i}\cdot x^{i}[/tex] (1)

Where:

[tex]y[/tex] - Dependent variable.

[tex]x[/tex] - Independent variable.

[tex]c_{i}[/tex] - i-th Coefficient of the polynomial.

[tex]n[/tex] - Grade of the polynomial

Let [tex]y[/tex] be a fourth-grade polynomial, then the expression must be in the form:

[tex]y = c_{o} + c_{1}\cdot c +c_{2}\cdot c^{2} + c_{3}\cdot c^{3} + c_{4}\cdot c^{4}[/tex] (2)

If we know that [tex]c_{o} = c_{1} = 0[/tex], [tex]c_{2} = 3[/tex], [tex]c_{3} = -10[/tex] and [tex]c_{4} = -1[/tex], then we have the following polynomial:

[tex]y = 3\cdot c^{2}-10\cdot c^{3}-c^{4}[/tex]

By Commutative Property:

[tex]y = -10\cdot c^{3}-c^{4}+3\cdot c^{2}[/tex]

We have a polynomial with three elements.

Therefore, the expression is a fourth grade trinomial.

Following are the calculation on the polynomial equation:

Given:

[tex]-10c^3 - c^4 + 3c^2[/tex]

To find:

degree of the polynomial=?

Solution:

[tex]\to -10c^3 - c^4 + 3c^2[/tex]

In the above given polynomial expression, we use the property of the polynomial expression therefore the degrees of the polynomial is "4".

Answer:

Answer:

22

Step-by-step explanation:

The result of 154 divided by 7 will be 22.

The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.

Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.

Since the given problem is not a large division. We can solve it by breaking 154 into two parts

    ______

7 / 154     \    2 2

   14

 ---------

   1 4

   14

---------

    0

Therefore, 22 will come from dividing 154 by 7.

Answer:

11) x = 4

12) x = 12

13) A = 45

14) A = 40

Step-by-step explanation:

All triangle angles must add up to 180 degrees. If they do not, the triangle is not considered a triangle.

So for triangle 11, solve using the equation: (16x + 4) + 47 + 65 = 180. First add 47 + 65 together to get 112. Subtract 112 from both sides to get (16x + 4) = 68. Subtract 4 from both sides to get 16x = 64. Divide 16 from both sides to get x = 4. Use the same technique for the other triangle.

For triangle 12, solve using the equation: (3x + 9) + 60 + 75 = 180. Add 60 + 75 to get 135. Subtract 135 from both sides to get (3x + 9) = 45. Subtract 9 from both sides to get 3x = 36. Divide 3 from both sides to get x = 12.

For triangle 13, solve using the equation: (62 + x) + (x + 51) + 79 = 180. For this equation, add the common variable first to get 113 + 2x + 79 = 180. You can still further simplify by adding 113 + 79 to get 192. The new equation is 192 + 2x = 180. Subtract 192 from both sides to get 2x = -12. Divide 2 from both sides to get x = -6. Now, to solve for angle A, insert the x value, -6, into Angle A's expression: x + 51. The x value would change the expression into -6 + 51. Solve to get 45. Use this technique for the other triangle as well.

For triangle 14, solve using the equation: 6x + 4x + 80 = 180. First add common variables to get 10x + 80 = 180. Subtract 80 from both sides to get 10x = 100. Divide both sides by 10 to get x = 10. To solve for Angle A, insert the x value, 10, in place of x. This turns the expression 4x into 4(10). Solve to get 40.

C. The results are inconclusive; therefore a generalization cannot be made regarding which option is selected more often.

explanation:

just took the test on plato

Since the study yields the same results for only five of the weeks. So here the generalization could be made like option c.

Since at the closing of the first week the company determined the majority of the employees should prefer the lunch break and also the company repeats the observational study for 10 more weeks.

So here the output is to be inconclusive. Due to this, the generalization cannot be made with respect to the selection of the given options.

hence, the option c is correct.
