Answer:

Option D

Step-by-step explanation:

Area of trapezium = sum of 2 parallel sides × height / 2

Here the two parallel sides are = 8 in. and 12 in.

And height = 7 in.

∴ Area of the trapezium = ( 8 + 12 ) × 7 / 2

= 20 × 7 / 2

=70 in^2

Answer:

C. Orthocentre

Step-by-step explanation:

The point of intersection of the altitude of a triangle is called orthocentre.

Explanation:

2g - (1/2)g = (4/2)g - (1/2)g = (3/2)g

The original equation becomes (1/2)g-4 = (3/2)g+4

The slopes are 1/2 and 3/2 respectively. Since the slopes are different, the two lines cannot be parallel.

Since we don't have parallel lines, they intersect at exactly one point leading to exactly one solution.

Answer:

the first one- one solution

the second one- infinitely many solutions

Step-by-step explanation:

One solution as one intersection point

=========

considering this equation as lines, these are two overlapping lines, so there are infinitely many solutions

Answer:

Answer:

To divide it into the above ratio we must first find the total parts which is

3 + 4 = 7

First part is

3/7 × 35

= 3 × 5

Second part is

4/7 × 35

= 4 × 5

Hope this helps you.

Explanation:

Refer to the diagram below. The angle theta is the angle of elevation formed between the horizontal line and the diagonal force being applied (the pulling force). Let x be the horizontal component pulling force, which is the horizontal portion of the right triangle. We know the hypotenuse of this triangle is 55 pounds as it is the force applied.

Use the cosine ratio to help solve for x. Make sure your calculator is in degree mode.

cos(angle) = adjacent/hypotenuse

cos(19) = x/55

x/55 = cos(19)

x = 55*cos(19)

x = 52.0035216579624 which is approximate

Roughly 52.0035216579624 pounds of force is being applied in a pure horizontal direction. The cart moves 30 feet, so,

work = (force)*(displacement)

work = (52.0035216579624)*(30)

work = 1560.10564973888

work = 1560.1 foot-pounds

A foot-pound is a unit of work, similar to how a joule is as well (though a joule measures in kilograms and meters)

Answer:

(6π + 16)cm² or 34.8 cm²

Step-by-step explanation:

square = 4 x 4 = 16 cm²

3 semi circles = 3 * 1/2 pi (2)² = 6pi cm² or 18.8 cm²

The area of the composite figure is (61 + 16) cm, the correct option is B.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The figure with three semi circles and square with side 2cm

Now,

Area of square

=4x4

=16

Area of 3 se semi circles

=3.14*2*3/2

=61

Total= 61+16

Therefore the area of composite figure will be (61 + 16) cm.

#SPJ7

Answer:

260

Step-by-step explanation:

a= 17

common difference (d ) = 19-17 = 2

a+(n-1)d = 35

17+(n-1)2 = 35

(n-1)2 = 35-17

n-1 = 18/2

n-1= 9

n = 9+1 = 10

Sum of the arithmetic sequence

= n/2[2a+(n-1)d]

= 10/2 [ 2(17)+ (10-1)2]

= 5(34+18)

= 5× 52

=260

Answer:

260

Step-by-step explanation:

Given the first and last terms in the sequence , calculate the sum using

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] (a + l)

where a is the first term and l the last term

Here a = 17 and l = 35

To calculate the number of terms use the n th term formula

[tex]a_{n}[/tex] = a + (n - 1)d

where d is the common difference

a = 17 and d = 19 - 17 = 2 and [tex]a_{n}[/tex] = 35, thus

17 + 2(n - 1) = 35 ( subtract 17 from both sides )

2(n - 1) = 18 ( divide both sides by 2 )

n - 1 = 9 ( add 1 to both sides )

n = 10

Hence

[tex]S_{10}[/tex] = 5(17 + 35) = 5 × 52 = 260

Answer:

88 cm²

Step-by-step explanation:

The perimeter of each square is 22 cm

we should divide by 4 to get the length of the square

22/4=5.5 cm

so we should multiply by 2 to get the length of the rectangle

5.5*2= 11

the perimeter is :

P= 5.5+5.5+5.5+11+11+5.5+5.5+11+11+5.5+5.5+5.5 =  88 cm²

Answer:

x = 6, y = 1

Step-by-step explanation:

-5x+10y = -20

5x-4y = 26

Adding both equations

=> -5x+10y+5x-4y = -20+26

=> 10y - 4y = 6

=> 6y = 6

Dividing both sides by 6

=> y = 1

Putting y = 1 in the first equation

=> -5x+10(1) = -20

=> -5x = -20-10

=> -5x = -30

Dividing both sides by -5

=> x = 6

Answer:

Step-by-step explanation:

Using the elemination method,

-5x + 10y = - 20

5x - 4y = 26

_____________

6y = 6

divide both sides of the equation by 6

6y/6 = 6/6

y = 1 --------> equation (i)

again,

Finding the value of X,

plugging the value of y from equation (i)

-5x + 10y = -20

or, -5x + 10*1 = -20

or, -5x + 10 = -20

or, -5x = -20-10

or, -5x = -30

or, x = -30/-5

X = 6

Hope this helps....

Good luck on your assignment..

Answer:

x=20°

Step-by-step explanation:

X and Z are inscribed with the same arc (40°)

so the value of x and z are the same

X=Z

Z=1/2(inscribed arc)

Z=1/2(40°)

z=20°..... since z=x

X=20°

Answer:

0

Step-by-step explanation:

Note that we start at (0, -4) and end at (7, -4).  Thus, the net change in y over the interval [0, 7] is 0, and the average rate of change of f(x) over that interval is thus

An arithmetic sequence there will be a constant difference between terms.

Option A: this sequence is not an arithmetic sequence as the difference between the 1st term and the 2nd term is ×[tex]\frac{1}{2}[/tex], but the difference between the 3rd term to the 4th term is ×[tex]\frac{1}{4}[/tex].

Option B: this sequence is an arithmetic sequence as the differences between every two consecutive terms are +5.

Option C: this sequence is not an arithmetic sequence as the difference between the 1st term and the 2nd term is -8, but in the difference between the 2nd term and the 3rd is +8.

Option D: this sequence is a typical fibonacci sequence, and clearly we can see that the differences are different in every two consecutive terms.

Answer:

Therefore, domain of y = [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)

Domain of y = [tex]\sqrt{x}+k[/tex] ; Domain = [0, ∞)

Step-by-step explanation:

Two functions are,

y = [tex]\sqrt{x-k}[/tex]

and y = [tex]\sqrt{x}-k[/tex]

Let the value of k = 1

Then we find the graph of the functions attached.

By analyzing these graphs,

y = [tex]\sqrt{x-1}[/tex] when shifted 1 unit right and 1 unit down we get a new function,

y = [tex]\sqrt{x}+1[/tex]

Therefore, domain of y = [tex]\sqrt{x-1}[/tex] ; Domain = [1, ∞)

Domain of y = [tex]\sqrt{x}+1[/tex] ; Domain = [0, ∞)

Similarly, domain of y =  [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)

And domain of y = √x + k ; Domain = [0, ∞)
