what is the sum of (-2.1×+3.7) and (5 + 4.9×)

Answer:

C.

Step-by-step explanation:

= [tex]\sqrt[3]{8}^{x}\\[/tex]

= Since [tex]\sqrt[3]{} = ^{1/3}[/tex]

= So, It becomes :

= [tex]8^{\frac{x}{3}[/tex]

Answer:

Common difference=5.

Answer:Its A

Step-by-step explanation:

Its A because its right believe me

equivalent to One-fourth x is One-half x + one-half x; equation 7 is correct

Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same. The given equation is equivalent to the expression one half and one half x.

Given information;

The expression given in the problem is,

(1/4) x [tex]x[/tex]

Equivalent expression;

Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.

For given expression,

1/4 x [tex]x[/tex]

As the above function is the function of x. Thus it can be written as,

f(x)= 1/4 x [tex]x[/tex]

The number four is the product of number 2 and number 2. Thus,

f(x)=(1/2x2) x [tex]x[/tex]

f(x)=(1/2 x 1/2) x [tex]x[/tex]

Hence the given equation is equivalent to the expression one half and one half x.

u do it like long multiplication just with decimals

6.8 times 1.6 = 10.88

Answer: 10.88

Step-by-step explanation:

6.8 x 1.6 = 10.88

you can multiply them without the decimals first then when you got the answer, you can count how many decimal places are there and place a decimal place where shoud be

=========================================================

Explanation:

f(x) = -x+9

f(0) = -0+9 .... replace x with 0

f(0) = 9

We will replace f(0) with 9 in the g(x) function. In other words, we plug in x = 9 into the g(x) function

This is because g( f(0) ) = g( 9 )

g(x) = x^2 - 6x + 9

g(9) = 9^2 - 6*9 + 9 ... replace x with 9

g(9) = 81 - 54 + 9

g(9) = 36

Therefore, g(f(0)) = g(9) = 36 or simply g(f(0)) = 36

-----------------------

Another method is to compute g(f(x)) algebraically first

g(x) = x^2 - 6x + 9

g(f(x)) = ( f(x) )^2 - 6*( f(x) ) + 9 .... replace every x with f(x)

g(f(x)) = ( -x+9 )^2 - 6*( -x+9 ) + 9 .... replace f(x) with -x+9

g(f(x)) = x^2 - 18x + 81 + 6x - 54 + 9

g(f(x)) = x^2 - 12x + 36

then we plug in x = 0

g(f(x)) = x^2 - 12x + 36

g(f(0)) = 0^2 - 12*0 + 36 ... replace x with 0

g(f(0)) = 36

Answer:

-The value of [tex]x[/tex]:

[tex]x = 3[/tex]

Step-by-step explanation:

-Solve for the value of [tex]x[/tex]:

[tex]-3x + 14 = 4x - 7[/tex]

-Subtract both sides by [tex]4x[/tex] and combine [tex]-3x[/tex] and [tex]-4x[/tex] together:

[tex]-3x + 14 - 4x = 4x - 4x - 7[/tex]

[tex]-7x + 14 = -7[/tex]

-Subtract both sides by [tex]14[/tex]:

[tex]-7x + 14 - 14 = -7 -14[/tex]

[tex]-7x = -21[/tex]

-Divide both sides by [tex]7[/tex]:

[tex]\frac{-7x}{-7} = \frac{-21}{-7}[/tex]

[tex]x = 3[/tex]

So, the final answer is [tex]x = 3[/tex].

Answer:

-72 + 4 = -68

Answer:

Step-by-step explanation:

Given the function f(x) = 1/4x -12. To get the inverse of the function, first we will let y = f(x) to have y = 1/4x - 12.

Then we will make x the subject of the formula as shown:

y = 1/4x - 12

adding 12 to  both sides we have;

y + 12= 1/4x - 12 + 12

y + 12 = 1/4x

Multiplying both sides by 4 we have;

4(y+12) = x

x = 4y + 48

Substituting y for x

y = 4x+48

f^-1(x) = 4x+48

h(x) = 4x+48

Thee final expression will give the inverse of the function

Answer:

h(x) = 4x+48

Step-by-step explanation:

Given the function f(x) = 1/4x -12. To get the inverse of the function, first we will let y = f(x) to have y = 1/4x - 12.

Then we will make x the subject of the formula as shown:

y = 1/4x - 12

adding 12 to  both sides we have;

y + 12= 1/4x - 12 + 12

y + 12 = 1/4x

Multiplying both sides by 4 we have;

4(y+12) = x

x = 4y + 48

Substituting y for x

y = 4x+48

f^-1(x) = 4x+48

h(x) = 4x+48

Thee final expression will give the inverse of the function

Answer: I am assuming it’s of a circle? So the answer would be rounded to 11.

Step-by-step explanation:

tan X = |YZ| / |XZ| = 20/8 = 5/2

X = arctan(5/2) = 68.2°

Answer: 68.2°

The size of angle ∠YXZ is 68.3° given that sides YZ=20cm and XZ=8cm by using trigonometric ratios.

In a right angled triangle, if A is an angle other than right angle then trigonometric ratios are

sin A =[tex]\frac{opposite side}{hypotenuse}[/tex]

cos A=[tex]\frac{adjacent side}{hypotenuse}[/tex]

tan A =[tex]\frac{opposite side}{adjacent side}[/tex]

Given YZ=20cm and XZ=8cm

Since the triangle is right angled, and opposite side and adjacent side are given we can find tan(∠YXZ )

tan (∠YXZ ) =20/8 =2.5

∠YXZ = arctan (2.5) =68.2°

Hence the size of angle ∠YXZ is 68.2° given that sides YZ=20cm and XZ=8cm.

Answer:

1/3

Step-by-step explanation:

let the common fraction be x

we get,

1/6 + x = 1/2

x = 1/2 - 1/6

x = 6 - 2/12

x = 4/12

x = 1/3

1/6 + x = 1/2

1/6 + 1/3 = 1/2

3 + 6/18 = 1/2

9/18 = 1/2

Answer:

Option (2).

Step-by-step explanation:

In the figure attached,

PB is a tangent and m(arc VU)= 80°, m(arc ST) = 40°

By theorem of angle between intersecting secants,

"If two secants have been drawn to a circle from a point outside the circle, then the angle between the secants will measure the half of the difference of the intercepted arcs."

[tex](m\angle 1)=\frac{1}{2}(m\widehat{VU}-m\widehat{ST})[/tex]

          [tex]=\frac{1}{2}(80-40)[/tex]

          = 20°

Therefore, Option (2) will be the answer.
