Answer:

Step-by-step explanation:

the ordinary form of 2.8 * 10^5 is

= 280000

Answer:

a) The complete square form =  ( x-11)² = 116

b)   x = 11 + 2√29

Step-by-step explanation:

Step(i):-

Given equation   x² = 22x -5

              ⇒ x² - 22x + 5 =0

             ⇒  x² - 2× 11 x + (11)² -(11)² + 5=0

            ⇒ ( x- 11)² -121 +5 =0

           ⇒  ( x-11)² = 116

The complete square form =  ( x-11)² = 116

Step(ii):-

           ⇒  (x-11) = √116 = √29 ×√4

           ⇒  x-11 = 2√29

          ⇒   x = 11 + 2√29

Answer:

3 hours

Step-by-step explanation:

Assuming that when the problem says "day" it refers to the hours of wakeness.  The problem is essentially asking to find 20% of 15.

First, convert 20% to decimal form. To do this, divide (20) by 100, this is because a percent is out of 100.

20 / 100 = 0.2

Now multiply the hours of wakeness by the percent as a decimal;

15 * 0.2 = 3

2x-3y=2 4x+7y= -9

2x=2+3y

2x=2+3y

2 2

x=2+3y 4(2+3y) + 7y= -9

2 2

8+12y + 7y= -9

8+12y+14y = -9

8+12y+14y= -18

26y= -26

26y = -26

26 26

y= -1

4x+7(-1)= -9

4x+(-7)= -9

4x-7= -9

4x = -2 now lets check,4(-1) + 7(-1)= -9 or 2(-1)-3(-1)=2

4 4 2 2

x=-1 -4 +(-7) = -9 -1-(-3)=2

2 2 -1+3=2

-2-7= -9 2=2

-9= -9

so the answer is x= -1 and y= -1

Answer:

D. (2, -1)

Step-by-step explanation:

I took the test and got it right.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).

Let the point be having coordinates (x,y).

If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

If the point is in the second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Triangle QRS is rotated 180° about the origin.

On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).

So, the coordinates of point S will be (2, -1).

Given:

The graph of a line.

To find:

The equation of the line.

Solution:

From the given graph it is clear that the line passes through the points (0,2) and (3,-2). So, the equation of the line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-2=\dfrac{-2-2}{3-0}(x-0)[/tex]

[tex]y-2=\dfrac{-4}{3}x[/tex]

Adding 2 on both sides, we get

[tex]y=-\dfrac{4}{3}x+2[/tex]

Therefore, the equation for the given line is [tex]y=-\dfrac{4}{3}x+2[/tex].

Answer:

The distance between point R and point Z is 7 blocks below.

Step-by-step explanation:

The question says the distance between Point r and Point Z. R to Z is going down. You start at R and find Z. When you have done that, You count the number of blocks or spaces that they have in between the space. And when you have counted you get your answer. The answer is never a negative number always positve even if the point is has a negative number with posivte or a negivate  with negative or a postive wwith a postive.

Answer:

13

Step-by-step explanation:

we know both triangles are congruent, so we can make an equation

3x+7=10x-7

take 3x from both sides

7=7x-7

14=7x

x=2

20-7=CAD

m<CAD is 13

The value of the angle CAD in the figure given is 13°.

So, the correct option is 1.

Given is a figure, we need to find the measure of the angle CAD,

To find the required measurement we will show the triangles ABD and ACD are congruent,

So, considering the Δ ABD and Δ ACD,

BD ≅ DC [marked in the figure]

∠B ≅ ∠C [all the right angles are ≅]

DA = DA [common in the both Δs]

Hence, Δ ABD ≅ Δ ACD by SSA rule.

We get, ∠CAD ≅ BAD by CPCTC.

Therefore,

3x + 7 = 10x - 7

Combining the like terms,

10x - 3x = 7 + 7

7x = 14

x = 2

Put x = 2 in ∠CAD = 3x + 7,

∠CAD = 3(2) + 7

∠CAD = 6 + 7

∠CAD = 13°

Hence, ∠CAD = 13°.

Answer:

True statements are:

(i) The lane 2 turtle is faster than the lane 1 turtle.

(iv) The lane 1 turtle has a head start.

Step-by-step explanation:

Now we proceed to check the value of truth for each choice:

(i) The lane 2 turtle is faster than the lane 1 turtle.

Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)

(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.

Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)

(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.

Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)

(iv) The lane 1 turtle has a head start.

According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)
