If a line is perpendicular to each of two intersecting lines at their point of intersection, then the line:

A. not enough information
B. is parallel to the plane determined by the two lines
C. coincides with the plane determined by the two lines
D. is perpendicular to the plane determined by the two lines

Answers

Answer 1

D. The line is perpendicular to the plane determined by the two lines.

Remember how you get to 3D space?

You take one axis called x and perpendicularly intersect it with y axis and you get a 2D plane. Now take a 2D plane and perpendicularly intersect it with an axis z and you get 3D euclidean space.

find the coordinates of the point satisfying lying on x axis at a distance of 5 units to the right of x axis lying on y axis at a distance of 3 units below the orgin

Answers

Answer:

(5, -3)

Step-by-step explanation:

Coordinates are located on Cartesian planes (more like locating a point on a graph). Cartesian coordinates can be two dimensional or three dimensional in nature depending on the number of axis we are considering. For the question, the dimension of the required coordinate is 2-dimensional i.e (x,y).

On the Cartesian plane, we have the x axis along the horizontal plane and y axis along the vertical.

Note that positive values lies towards the right of the x-axis and also up the y-axis. The negative values lies towards the left of the x-axis and also down the y-axis.

According to the question, if a point is lying on x axis at a distance of 5 units to the right of x axis, then the value of x will be +5 i.e x = +5

Also, if a point lies on the y axis at a distance of 3 units below the origin, then the value of y will be -3 i.e y = -3.

Hence, the coordinates satisfying this points (x,y) is (5, -3)

A number is doubled, then decreased by 13.7. The result is greater than 125.28. What is the smallest integer that satisfies this condition?

Answers

Answer:

x > 69.49

Step-by-step explanation:

Step 1: Write out equation

2x - 13.7 > 125.28

Step 2: Add 13.7 to both sides

2x > 138.98

Step 3: Isolate x by dividing both sides by 2

x > 69.49

So x has to be greater than 70 in order to fit into the question context.

Answer:

70

Step-by-step explanation:

Let x be the desired integer. Then 2x-13.7>125.28. Adding 13.7 to both sides gives 2x>138.98, and dividing both sides by 2 gives x>69.49. The smallest integer that is greater than 69.49 is [tex]$\boxed{70}$[/tex].

Determine the sum of the first 7 terms of the arithmetic sequence with
general formula t_n = -3n +7

Answers

Answer:

your answer is -35.

Step-by-step explanation:

let the first 7 terms be 1,2,3,4,5,6, and 7.

we have ,

general term t_n = -3n +7 ,then

t_1 = -3*1 +7

= -3+7

= 4

t_2 = -3*2 +7

= -6 +7

= 1

t_3 = -3*3 +7

= -9+7

= -2

t_4 = -3*4 +7

= -12+7

= -5

t_5 = -3*5 +7

= -15+7

= -8

t_6 = -3*6 +7

= -18+7

= -11

t_7 = -3*7 +7

= -21+7

= -14

Now, the sum of first seven terms is

4 + 1 + (-2) + (-5) + (-8) + (-11) + (-14)

= 5 -2 - 5 - 8 - 11 - 14

= -35

Answer:

-35

Step-by-step explanation:

Sum of the first 7 terms of AP is:

S_7= 1/2*7(t_1 + t_7)

As per general formula t_n= -3n +7 we find the first and seventh terms and the sum of the first 7 terms:

t_1= - 3*1 + 7= 4t_7= - 3*7 + 7= - 14S_7 = 7/2*(4-14)= 7/2*(-10)= - 35

In how many ways can you arrange 4 different colored balls? 4,8,4!,3!,5!

Answers

Answer:

We can arrange 4 different colored balls in 24 ways.

Step-by-step explanation:

We have to find the number of ways in which we can arrange 4 different colored balls.

Firstly, we have to decide that either we use Permutation or we use Combination.

A Permutation is used when the order of arranging the numbers matters while on the other hand, a combination is used when the order of arranging the numbers doesn't matter.

So, in our question; the ordering matters to us as a ball which is placed in the first place can't be put again put in other places.

Number of ways of arranging 4 different colored balls = [tex]^{4}P_4[/tex]

                     =  [tex]\frac{4!}{(4-4)!}[/tex]          {[tex]\because ^{n} P_r = \frac{n!}{(n-r)!}[/tex] }

                     =  4! = [tex]4 \times 3 \times 2\times 1[/tex]

                     =  24 ways

Hence, we can arrange 4 different colored balls in 24 ways.

ΔADC ~ ΔACB,          Given

AC/AD = BA/AC,        The ratio of corresponding sides of similar triangles

b/e = c/b

b² = c·e

ΔBDC ~ ΔBCA,           Given

BC/BA =  BD/BC,        The ratio of corresponding sides of similar triangles

a/c = d/a        

a² = c·d

a²  + b²   = c·e + c·d

a²  + b²   = c · (e + d)

B because the temperature of the water changes constantly

Answer:

A. The time you take your dog for a walk each day

B. The temperature of the water in the local river during the day

C. How long it takes to run a lap around the track  

Step-by-step explanation:

Continuous data is quantitative data that you can measure. It can have an infinite number of possible values within a given range.

For example, you can measure times and temperatures to any number of decimal places if you have the appropriate equipment.

D is wrong. You can't measure the number of croutons in a salad. You must count them.

You want to find the area of the front of a house whose shape is a triangle on top of a rectangle with a width of 11. The triangle's height is 13 and the rectangle's height is 7. What is the total area of the front of the house? Round to the nearest tenth. Do not include square units in your answer.

Answers

Answer: 148.5

Step-by-step explanation:

To find the area of this shape, comprised of a rectangle and a triangle, we can find the area of each shape and add them together.

The area of a triangle is 12⋅b⋅h. We are given the triangle's height, 13. The base of the triangle will be the same as the width of the rectangle, which we also know: 11. Now we can calculate the area of the triangle:

A = 1/2⋅b⋅h

A = 12⋅11⋅13

A = 71.5

Now we can find the area of the rectangle, which is l⋅w. The width of the rectangle is 11, which is the same as the base of the triangle; the length is 7:

A =l⋅w

A = 7⋅11

A = 77

Finally, we can add together the area of the triangle and the rectangle to find the total area:

A = 71.5 + 77 = 148.5

The total area of the front of a house will be 148.5.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

A rectangle has a width = 11

The triangle's height = 13

The rectangle's height = 7

Now,

Since, The base of the triangle will be the same as the width of the rectangle.

Hence, The area of rectangle = 7 x 11

                                              = 77

And, The area of triangle = 1/2 x 11 x 13

                                      = 71.5

Thus, The total area of the front of a house = 77 + 71.5

                                                                  = 148.5

Therefore, The total area of the front of a house will be 148.5.

next subtract 2x from both sides:

18+6x-2x=2x-2x+42, which becomes 18+4x=42

then subtract 18 from both sides:

18-18+4x=42-18, which becomes 4x=24

Step-by-step explanation:

The surface are is given by this formula:

Sa= area of the base*the heigth + the area of the base *2

●●●●●●●●●●●●●●●●●●●●●●●●

2)

The base here has a triangular form.

Let A be the area of this triangle.

A= (6*8)/2 = 24 cm^2

Sa = A* 6 + A*2

Sa= 24*6 + 24*2

Sa = 192 cm^2

●●●●●●●●●●●●●●●●●●●●●●●●

The base here is a circle.

The area of a circle is :

A= r^2 * Pi

r is the radius (here 12 km)

A = 12^2* Pi

A= 144 Pi cm^2

Sa = 2*A + A* h

Sa = 7* 144* Pi + 2* 144* Pi

Sa= 4071.504

So the surface area is aporoximatively 4072 km^2

Answer:

To eliminate solve for y, we need to eliminate x and we will do that by multiplying the first  equation by 8   and multiply the second equation by 9.

y=6

Step-by-step explanation:

In the equations:

9x + 3y = -18  -----------------------------------------------------------------(1)

8x + 7y = 10 --------------------------------------------------------------------(2)

To solve for  y, we will have to eliminate x

To eliminate x, we will follow the steps below;

multiply equation (1) through by 8   and multiply equation (2) through by 9

The resulting equations are
