How many terms are in the expression shown below?


a2 - ab + 8b + b2 - 1

Answer:

1.3

Step-by-step explanation:

BC is the distance between B and C.

BC = x − (-0.4)

BC = x + 0.4

AB is the distance between A and B.

AB = -0.4 − (-1.25)

AB = -0.4 + 1.25

AB = 0.85

Substitute into the equation.

BC = 2AB

x + 0.4 = 2(0.85)

x + 0.4 = 1.7

x = 1.3

Answer:

x=1.3

Step-by-step explanation:

AB=(-0.4-(-1.25))=1.25-0.40=0.85

BC=2AB=2×0.85=1.70

x=-0.4+1.7=1.3

The right answer is 10 units.

Answer:

35.92 m

Step-by-step explanation:

To have a better comprehension of the problem, we can draw it as in the image attached.

If we use the tangent relation in both triangles, we have:

tangent(35) = h/x

tangent(20) = h/(150-x)

From the first equation, we have:

x = h/tangent(35) = h/0.7

From the second equation, we have:

0.364 = h / (150 - h/0.7)

54.6 - 0.52h = h

1.52h = 54.6

h = 35.92 m

Answer:

Step 1: Substitute the value of x into the equation

x= 3-3/2y

-3x+5y=10

Step 2: Solve the equation

-3(3-3/2y)+5y=10

Step 3: Substitute the value of y into the equation

Y=2

Step 4: Solve the equation

X=3-3/2×2 = X=0

Answer: (0,2)

Answer: 67.2°

Step-by-step explanation:

To find angle C, we have to use cosine rule. Therefore,

12² = 8² + 10² - 2 × 8 × 10 × cosC

C = 82.8°

The bearing of A from C will be

= 150° - 82.8°

= 67.2°.

So the value of z is 10.

Answer:

THE 2 ONE

Step-by-step explanation:

Answer:

1 / (99 - 40x).

Step-by-step explanation:

The whole of g(x) is input to f(x), so:

we replace the x in f(x) by g(x).

f(g(x)) =  1 /  [8(12 - 5x) + 3]

=  1 /( 96 - 40x + 3)

= 1 / (99 - 40x).

Answer:

A=266CM

Step-by-step explanation:

p=2l + 2w                                   l=2x+1             w=x+5

66=2[2x+1] + 2{x+5]                  l=2x9 + 1           w=9+5

66=4x+2 + 2x+10                      l=18+1                 w=14

66=6x+12                                   l=19

66-12=6x

54=6x                                      A=L x W

x=9                                         A=19 x 14

                                             A=266CM

Answer:

enlargment and 6.4 feet per inch

Step-by-step explanation:

i got it right on mine

The blank words are:

Enlargement and 6.4.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A company plans to scale its logo and place it on a billboard so that drivers and pedestrians can see it easily from the ground.

The original logo is a square with sides of 1.25 inches.

After scaling,

the local must have a perimeter of 32 feet.

This action is called enlargement,

and the scale factor is,

= (32/4) / 1.25

= 8 / 1.25

= 6.4.

Therefore, the scale factor is 6.4.

Answer:

87 feet

Step-by-step explanation:

Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:

30+9+12+9+9+9+9=87 feet

Hope this helps!

Answer:

The perimeter of this shape is 87 ft.

Step-by-step explanation:

Given that all side lengths are added together in order to find perimeter. So the perimeter is :

[tex]perimeter = 9 + 9 + 9 + 12 + 9 + 30 + 9[/tex]

[tex]perimeter = 45 + 30 + 12[/tex]

[tex]perimeter = 87 \: feet[/tex]

We have been given image of a circle. We are asked to find the measure of angle WTV.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle WTV is inscribed angle to arc WV. So measure of angle WTV will be half the measure of arc WV.

[tex]\angle WTV=\frac{1}{2}\widehat{WV}[/tex]

[tex]\angle WTV=\frac{1}{2}\cdot 90^{\circ}[/tex]

[tex]\angle WTV=45^{\circ}[/tex]

Therefore, the measure of angle WTV is 45 degrees and 2nd option is the correct choice.

Answer:

Step-by-step explanation:

In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted [tex]Fn[/tex], form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Given data

First term= n

second term = 3n

third term = 4n

According to Fibonacci sequence the fourth term is

[tex]F4= F2 + F3\\F4=3n+ 4n= 7n[/tex]

the Fifth term is

[tex]F5= f3 + f4\\f5= 4n+7n= 11n[/tex]

hence  the sixth term is

[tex]F6= F4+F5\\ F6= 7n+11n= 18n[/tex]
