(a) Complete the table of values for y = 6 - 4x.
Please help ❤️
Answer:
[tex]\boxed{\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}}[/tex]
Step-by-step explanation:
Given equation to us is :-
[tex]\implies y = 6 - 4x [/tex]
So , here we can put different values of x in order to get different values of y .
Initial table given to us is ,
[tex]\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & & & 2&&-6 \\\cline{1-6}\end{tabular}[/tex]
Put x = (-1) :-
[tex]\implies y = 6 - 4x \\\\\implies y = 6 -4(-1) \\\\\implies y = 6 + 4 \\\\\red{\bf\implies y = 10} [/tex]
Put x = 0 :-
[tex]\implies y = 6 - 4x \\\\\implies y = 6-4(0) \\\\\implies y = 6 - 0 \\\\\pink{\bf\implies y = 6 }[/tex]
Put x = 2 :-
[tex]\implies y = 6-4x \\\\\implies y = 6 - 4(2) \\\\\implies y = 6 - 8 \\\\\blue{\bf\implies y = (-2)} [/tex]
Hence the final table would be :-
[tex]\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}[/tex]

If Sin theta=3/4,find the value of cos theta
Answer:
[tex]Cos \ \theta = \frac{\sqrt{7} }{4}[/tex]
Step-by-step explanation:
Given;
Sin θ = 3/4
To calculated Cos θ;
make a sketch of right-angled triangle with following sides;
opposite side = 3
hypotenuse side = 4
then, the adjacent side will be calculated from Pythagoras theorem;
let the adjacent side = b
b² = 4² - 3²
b² = 16 - 9
b² = 7
b = √7
Therefore, Cos θ is now calculated as;
Cos θ = adjacent / hypotenuse
Cos θ = √7/4
[tex]Cos \ \theta = \frac{\sqrt{7} }{4}[/tex]
Therefore, [tex]Cos \ \theta = \frac{\sqrt{7} }{4}[/tex]
Choose the polynomial that is described. A trinomial in one variable of degree 3.a. 4r2-9t+7b. 3r2+4t-9 c. 4r3 d. 4r3 -9t +7
Answer:
C. 4r³
Step-by-step explanation
A trinomial is an expression having three terms. A polynomial with degree 3 that which its leading variable has a power of 3. For example an example of such polynomial in one variable is expressed as 2x³+4x²-7. This equation has 3 terms and the leading variable has a power of 3 with only x as the variable
From the given options based on the explanation, the correct answer will be 4r³. This can also be written as a trinomial as 4r³+0r²+0r
The rest contains more than one variable.
There is no trinomial.
A trinomial is a polynomial with three nonzero terms
Here we have to find trinomial in one variable of degree 3 .
Since in given four options a , b , d have equations in two variables and c have only one term so there is no trinomial.

If the point (8,-5) is 6 units above the point P(x, y) and 3 units to the right of it, then what are the coordinates of
the point P(x, y)?
Answer:
(5, -11)
Step-by-step explanation:
We know that (8, -5) is 6 units above and 3 units to the right of point P. Knowing this, let's work backwards by starting from (8,-5) and counting 6 units down and 3 units to the left on the graph.
If you counted correctly, this should place you at the (5, -11). (You can also check your work by counting 6 units up and 3 units to the right from (5, -11) and seeing if you end up at (8, -5).)

f)300 worker-hours and $10,000 in capital expenditure
Answer:
d)900 worker-hours and $5000 in capital expenditure
Step-by-step explanation:
From the question we are told that
Daily output at a plant manufacturing chairs is approximated by the function [tex]f(L,K) = 45\sqrt[3]{K}L^3^/^5[/tex]
Daily budget of $13,000
Average wage of an employee is $9.00 per hour
a) Generally the function [tex]f(L,K) = 45\sqrt[3]{K}L^3^/^5[/tex] can be use to for (a)
Mathematically solving with L=200 K=9000
[tex]f(L=200,K=9000) = (45\sqrt[3]{9000})200^3^/^5[/tex]
[tex]f(L=200,K=9000) = 45*20.8*24[/tex]
[tex]f(L=200,K=9000) = 22464[/tex]
b)Generally the function [tex]f(L,K) = 45\sqrt[3]{K}L^3^/^5[/tex] can be use to for (b)
Mathematically solving with L=1100 K=3000
[tex]f(L=1100,K=3000) = (45\sqrt[3]{3000})1100^3^/^5[/tex]
[tex]f(L=1100,K=3000) = 45*14.4*66.8[/tex]
[tex]f(L=1100,K=3000) = 43286.4[/tex]
c)Generally the function [tex]f(L,K) = 45\sqrt[3]{K}L^3^/^5[/tex] can be use to find (c)
Mathematically solving with L=500 K=8000
[tex]f(L=500,K=8000) = (45*\sqrt[3]{8000})*500^3^/^5[/tex]
[tex]f(L=500,K=8000) = 45*20*41.63[/tex]
[tex]f(L=500,K=8000) =37467[/tex]
d)Generally the function [tex]f(L,K) = 45\sqrt[3]{K}L^3^/^5[/tex] can be use to find (d)
Mathematically solving with L=900 K=5000

F
Answer:
140
Step-by-step explanation:
115+165+140+90=510
180*4=720 (sum of interior angles of hexagon)
115+165+140+90+x+2x=720
why 2x because i kept ANGLE DEF as x and ANGLE CDE is twice so 2x
510+2x+x=720
3x=210
x=210/3
x=70
ANGLE DEF IS 70
so because ANGLE CDE IS TWICE ANGLE DEF thus 70*2=140
ANGLE CDE =140
The angle CDE is 140°.
What is a hexagon?
A hexagon can be defined as a closed two-dimensional polygon with six sides. Hexagon has 6 vertices and 6 angles.
According to the given problem,
We know,
Sum of the interior angles of a polygon is,
Sum = 180° (n - 2) where n is the number of sides,
Here n = 6 , then
Sum = 180° × 4 = 720°
Let ∠ DEF be x
Therefore ∠ CDE = 2x,
Sum the interior angles,
⇒ 160 + 90 + 145 + 115 + 2x + x = 720
⇒ 510 + 3x = 720 ( subtracting 510 from both sides )
⇒ 3x = 210 ( dividing both sides by 3 )
⇒ x = 70
∠ CDE = 2x
= 2 × 70
= 140°
Hence, we can conclude, in the hexagon, the angle CDE is 140°.

A bucket holds 4 liters of water. If a ladle can scoop out 14 of a liter, how many scoops will it take to empty the bucket?
Step-by-step explanation:
the ladle should scoop out 56 scoops to empty the bucket because if one scoop equals 1/14, there are 14 scoops per liter, and 4 liters, so 4 times 14 equals 56
The ladle should scoop out 56 scoops to empty the bucket
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity
Given,
A bucket holds 4 liters of water.
If a ladle can scoop out 14 of a liter We need to find how many scoops will it take to empty the bucket
We know that one scoop equals 1/14 liters
1 scoop=1/14 litres
1 litre=14 scoops
As there are 4 litres
We have to multiply 14 with four to find the number of scoops to take to make the bucket empty.
14×4
56
Hence, the ladle should scoop out 56 scoops to empty the bucket

Suppose the system below is consistent for all possible values of f and g. What can you say about the coefficients c and d? Justify your answer. x1 + 3x2 = f cx1 + dx2 = g
Answer:
The answer is "[tex]d \neq 3c,[/tex]f and g are arbitrary".
Step-by-step explanation:
The matrix of the device is increased
[tex]\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right][/tex]
Reduce the echelon row matrix
[tex]\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right] \\\\R_1 \leftrightarrow R_2 \\\\\frac{R_2 -1}{C R_1 \to R_2} \sim \left[\begin{array}{ccc} c&d&g\\ 0 & \frac{3c-d}{c}& \frac{cf-g}{c}\\ \end{array}\right][/tex]
Therefore, if 3c[tex]\neq[/tex] 0 is d [tex]\neq[/tex] 3c, the device is valid. Therefore d [tex]\neq[/tex] are arbitrary 3c, g and f.
The values of the coefficients c and d are 1 and 3, respectively
The system of equations are given as:
[tex]x_1 + 3x_2 = f[/tex]
[tex]cx_1 + dx_2 = g[/tex]
From the question, we understand that the system of equations is consistent.
Assume that the system of equations is also dependent, then it means that:

Lucas opened a savings account 20 years ago with a deposit of $3,815.24. The account has an interest rate of 3.3% compounded
quarterly. How much interest has Lucas earned?
a. $3,488.21
b. $3,546.50
c. $3,815.24
d. $3,941.14
Answer:
Interest earned = $3546.50
Option B is correct option.
Step-by-step explanation:
Time t = 20 years
Principal Amount P =$3815.24
Interest r = 3.3% or 0.033
Compounded quarterly n = 4
We need to find How much interest has Lucas earned?
First we need to find the future value in the account after 20 years
The formula used to find future value A is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values of t, r , n and P to find A i.e future value
[tex]A=P(1+\frac{r}{n})^{nt}\\A=3815.24(1+\frac{0.033}{4})^{20*4} \\Simplifying:\\A=3815.24(1+0.00825)^{20*4} \\A=3815.24(1.00825)^{80}\\A=3815.24(1.929)\\A= 7361.74[/tex]
Now finding interest amount by subtracting the initial deposit from the future value
Interest earned = Future Value (A)- Initial Deposit (P)
Interest earned = 7,361.74 - 3815.24
Interest earned = 3546.50
So, Lucas have earned interest = $3546.50
Option B is correct option.
