Answer:

k=4

Explanation:f(x)=x3+4x2−kx+1By the remainder theorem, the remainder when dividing a polynomial f(x)by (x−a)

is f(a)In our case, we have a=−1 and we need:0=f(−1)=(−1)3+4(−1)2−k(−1)+10=f(−1)=−1+4+k+10=f(−1)=k+4

Hence k=−4

Taxable income is the income that is reached by taxes established by the government, that is, those sums of money from individuals that the government levies with a tax contribution. The so-called deductions are deducted from these sums, with which the apportionment between taxable income and deductions results in the final amount of taxes to be paid.

Answer:

x = 9.9 or 10

Step-by-step explanation:

to find missing angle -->

90 + 61 + z = 180

151 + z = 180 *subtract 151 from both sides*

z = 29

to find x -->

tan (29) = x/18 *put tan(29) over 1 then cross multiply*

x = 18 (tan(29))

x = 9.97 --> round up to 10

Answer:

320 kilometers

Step-by-step explanation:

1/2 -- (60 * 2) = 120 km

rest pf the trip -- 100 km per hour -- 2 hours left -- (100 * 2) = 200 km

Therefore, 120 + 200 = 320 km

Answer:

6

Step-by-step explanation:

From question:

Dan has put his coins into 2 stacks

2 stacks in total

Each stack has the same number of coins

Number of coins in stack 1 = number of coins in stack 2

x = x

There are 12 coins total

Total number of coins in 2 stacks = 12

2x = 12

x = 6

There are six coins in one stack.

Answer:

Hence, the relation R is a reflexive, symmetric and transitive relation.

Given :

A be the set of all lines in the plane and R is a relation on set A.

[tex]R=\{l_1,l_2\in A|l_1 \;\text{is parallel to}\; l_2\}[/tex]

To find :

Which type of relation R on set A.

Explanation :

A relation R on a set A is called reflexive relation if every [tex]a\in A[/tex] then [tex](a,a)\in R[/tex].

So, the relation R is a reflexive relation because a line always parallels to itself.

A relation R on a set A is called Symmetric relation if [tex](a,b)\in R[/tex] then [tex](b,a)\in R[/tex] for all [tex]a,b\in A[/tex].

So, the relation R is a symmetric relation because if a line [tex]l_1[/tex] is parallel to the line [tex]l_2[/tex] the always the line [tex]l_2[/tex] is parallel to the line [tex]l_1[/tex].

A relation R on a set A is called transitive relation if [tex](a,b)\in R[/tex] and [tex](b,c)\in R[/tex] then [tex](a,c)\in R[/tex] for all [tex]a,b,c\in A[/tex].

So, the relation R is a transitive relation because if a line [tex]l_1[/tex] s parallel to the line [tex]l_2[/tex] and the line [tex]l_2[/tex] is parallel to the line [tex]l_3[/tex] then the always line [tex]l_1[/tex] is parallel to the line [tex]l_3[/tex].

Therefore the relation R is a reflexive, symmetric and transitive relation.

Answer:

They would sill be the same because just because the other shape is lopsided doesn't mean its different than the other. They can me moved left or right but they will still have the same volume.

Step-by-step explanation:

As 3D shearing transformations preserves the volume of figure, the volumes of the two figures would be the same.

"Shearing is the process of slanting a three- dimensional geometrical object in 3-D space either in x, y, or in the z-direction."

For given example,

We can observe that figure 2 is a result of shearing transformation on figure 1.

We know, a three-dimensional shearing transformation preserves the volume of solid figures.

This means, the volume of both the figures is same.

Also, we can observe that the length, width and height of the both figures are equal.

Therefore, the volumes of the two figures would be the same.

Answer:

The total charges for the two checking accounts will be the same after 6 checks written.

Step-by-step explanation:

Since I want to open a checking account at my local bank which offers two options, a standard checking account that charges $ 6 each month plus $ 0.25 for each check written, and a select checking account that charges $ 4.50 each month plus $ 0.50 for each check written, to determine which system of equations can be used to determine the number X of checks that must be written in a month in order for the total charges Y for the two checking accounts to be the same, the following calculation must be performed:

6 + 0.25X = Y

4.5 + 0.5X = Y

6 + 0.25x5 = Y

4.5 + 0.5x5 = Y

6 + 1.25 = Y = 7.25

4.5 + 2.50 = 7

6 + 0.25x6 = Y

4.5 + 0.5x6 = Y

6 + 1.50 = Y = 7.50

4.5 + 3 = 7.50

Therefore, the total charges for the two checking accounts will be the same after 6 checks written.

Answer:

One regular price ticket cost $40

Step-by-step explanation:

First yo would have to add back the $20 that they saved to the total which would be $120 total and then since that was the total for all 3 of them you would do $120 divided by 3 which would be $40 for each ticket regularly.

Circumference of given circle = 154 cm² (Approx.)

Step-by-step explanation:

In given diagram:

Diameter of given radius = 49 cm

Value of π = 3.14

Find:

Circumference of given circle

Computation:

Radius of given circle = Diameter of given radius / 2

Radius of given circle = 49 / 2

Circumference of given circle = 2πr

Circumference of given circle = 2(3.14)(49/2)

Circumference of given circle = (6.28)(49/2)

Circumference of given circle = 153.86

Circumference of given circle = 154 cm² (Approx.)
