use a calculator and work out the following and write all the figures from your work display. a) (6.2 - 3.51) x (11.7 x 0.3)
Answer:
Solving the expression: [tex](6.2 - 3.51) \times (11.7 \times 0.3)[/tex] we get 9.4419
Step-by-step explanation:
We need to solve the expression: [tex](6.2 - 3.51) \times (11.7 \times 0.3)[/tex]
According to DMAS rules first we solve brackets and then we will multiply the results found after solving brackets
So,
[tex](6.2 - 3.51) \times (11.7 \times 0.3)\\=2.69 \times 3.51\\=9.4419[/tex]
First we solved the terms (6.2-3.51) and get 2.69 and by solving (11.7 x 0.3) we get 3.51
Now, we will multiply 2.69 with 3.51 to get the final result.
The final result is 9.4419
So, solving the expression: [tex](6.2 - 3.51) \times (11.7 \times 0.3)[/tex] we get 9.4419

Answer/Step-by-step explanation:
Given, y = k√x
Let's find the following:
a. To find k, using the first pair given, (64, 16), plug in the values of the ordered pair into y = k√x
Thus:
16 = k√64
16 = k*8
Divide both sides by 8
16/8 = k
k = 2
b. To find F, substitute k = 2, and x = 100 into y = k√x
Thus:
y = 2√100
y = 2*10
y = 20
F = 20
c. To find x, substitute k = 2, and y = 10√2 into y = k√x.
Thus:
10√2 = 2√x
Divide both sides by 2
(10√2)/2 = √x
5√2 = √x
Square both sides
x = (5√2)²
x = 25*2
x = 50
d = 50
6x + 2 + 3x + 1 =

Given f(x) = 4(3 – X), what is the value of f(-5)?
Hi there.
To find the value of f(-5), we need to substitute x = -5 in the equation.
[tex]f( - 5 ) = 4(3 - ( - 5))[/tex]
Now then, know the basic rules of multiplying in the negative.
When you multiply the negative with the negative, you will get the positive.
Thus, - (-5) = 5
[tex]f( - 5) = 4(3 + 5) \\ f( - 5) = 4(8)[/tex]
Then distribute 4 inside.
[tex]f( - 5) = 32[/tex]
Therefore, the answer is f(-5) = 32

What is the equation of the line that is parallel to the
given line and passes through the point (12, -2)?
Oy=-x +10
Oy=-x + 12
Oy=-x- 10
Oy=x - 12
Answer:10
Step-by-step explanation:and a slope 2/12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance.Aug
The equation of the line that is parallel to the given line and passes through the point (12, -2) is y = 5/6(x)-12
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The slope of line passing through the points (12, 6) and (0, -4)
Slope = -4-6/0-12
=-10/-12
=5/6
Now let us find y intercept passing through (12, -2)
-2=5/6(12)+b
-2=10+b
-12=b
Hence, the equation of the line that is parallel to the given line and passes through the point (12, -2) is y = 5/6(x)-12

Given:
(x+2) is a factor of polynomial f(x).
To find:
The correct statement.
Solution:
If (x-c) is a factor of polynomial f(x), then c is a zero of the polynomial and f(c)=0.
We have, (x+2) is a factor of polynomial f(x).
On comparing (x-c) and (x+2), we get
[tex]c=-2[/tex]
It means, -2 is a zero of the polynomial f(x) and the value the polynomial at x=-2 is 0, i.e.,
[tex]f(-2)=0[/tex]
Therefore, the correct option is d.

What do you think x equals?
Answer:
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

34. Find the equation of the straight line which
.
passes through the point (3,1) and makes
intercepts on the axes the difference of
whose length is 4.
Answer:
The equation of the straight line passing through the point ( 3,1 )
[tex]\frac{x}{2} + \frac{y}{-2} = 1[/tex]
Step-by-step explanation:
Step(i):-
The equation of the straight line passing through the point ( 3,1 )
[tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]
[tex]\frac{3}{a} + \frac{1}{b} = 1[/tex]
3b + a = ab ...(i)
Given the difference of length is 4
a-b = 4
b = a - 4 ...(ii)
Step(ii):-
substitute b=a-4 in equation (i) , we get
3( a-4 ) + a = a (a-4)
3a - 12+ a = - 4 a + a²
a² - 8 a + 12 =0
Find the factors of 'a'
a² - 6a -2a +12 =0
a (a-6) -2(a-6) =0
a =2 and a=6
we know that a-b =4
put a = 2
2 - b =4
b = -2
The equation of the straight line whose intercepts on the axes
[tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]
[tex]\frac{x}{2} + \frac{y}{-2} = 1[/tex]
The equation of the straight line
[tex]\frac{x}{2} + \frac{y}{-2} = 1[/tex]
Verification:-
The equation of the straight line passing through the point (3,1)
[tex]\frac{x}{2} + \frac{y}{-2} = 1[/tex]
Put x =3 and y=1
[tex]\frac{3}{2} + \frac{1}{-2} = 1\\\frac{2}{2} =1\\[/tex]
1 = 1
∴ The point (3,1) is satisfies the equation
