2. Triangle ABC and triangle EFD ARE ?PLEASE HELP

Answer:

12.68

Step-by-step explanation:

With reference angle 45°

perpendicular (p) = 9

hypotenuse (h) = c

Now

sin 45 ° = p/ h

0.71 = 9 / c

c = 9 / 0.71

c = 12.68

Hope it will help :)

Answer:

Please check the explanation.

Step-by-step explanation:

Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.

In other words,

P(x, y) → P'(-y, x)

From the given triangle ΔRST,

The coordinates of the point S is:

According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:

S(10, 1) → S'(-1, 10)

Here,

S'(-1, 10)  is the image of the original point or pre-image point S(10, 1).

Therefore, the y-coordinate of the point S' is: 10

Answer:

[tex]40\ \text{inches}[/tex]

Step-by-step explanation:

[tex]\theta[/tex] = Angle = [tex]5.7^{\circ}[/tex]

Let the vertical distance be is [tex]y=4\ \text{inches}[/tex]

horizontal distance be [tex]x[/tex]

So, slope is the tangent of the angle between the vertical and horizontal

[tex]\dfrac{y}{x}=\tan\theta\\\Rightarrow \tan5.7^{\circ}=\dfrac{4}{x}\\\Rightarrow x=\dfrac{4}{\tan5.7^{\circ}}\\\Rightarrow x=40.07\approx 40\ \text{inches}[/tex]

The horizontal distance for flared sides is [tex]40\ \text{inches}[/tex].

The horizontal distance for flared sides with a 4 inch vertical distance is 40.1 inches

Represent the horizontal distance with h, and the vertical distance with v.

The ratio of the vertical to the horizontal distance is given as: 5.7 degrees.

This means that:

[tex]\tan(5.7) = \frac{v}{h}[/tex]

Make h the subject

[tex]h = \frac{v}{\tan(5.7)}[/tex]

The vertical distance is given as 4 inches.

So, we have:

[tex]h = \frac{4}{\tan(5.7)}[/tex]

Evaluate tan(5.7)

[tex]h = \frac{4}{0.0998}[/tex]

Divide

[tex]h = 40.1[/tex]

Hence, the horizontal distance is 40.1 inches

Step-by-step explanation:

To add fractions, find the LCD and then combine.

Answer:

7/10

Step-by-step explanation:

First, find the smallest possible denominator between the two fractions. The smallest one is 20.

Now, both denominators need to become 20. To get the 5 in 1/5 to become 20, it needs to be multiplied by 4. Whatever you do to the denominator, you must do to the numerator.

1 x 4 = 4

The first fraction is now 4/20.

To get the 4 in 2/4 to become 20, you must multiply it by 5. Whatever you do to the denominator, you must do to the numerator.

2 x 5 = 10

The second fraction is now 10/20.

Add the fractions. Keep the denominators the same and add the numerators.

4/20 + 10/20 = 14/20

Simplify by dividing both numbers by 2

id-k but here we go

have you seen things of circles and triangles and squares? This problem is just like this. You would probably identify the squares circles and triagnles as...well....traingles circles and squares. Well, we do that but with the variables.

The numbers with 'x' is one group. And the one without it is another group. So....take 'x3' and take the x9. Because they have the same variable.

x3 +  x9. (why we are adding is because it has nothing to drag with it and both of these numbers are positive)

x12!

Now do teh same with 15 and 3. Bring the plus and the subtraction sign with 3 and 15. We cant just leave them there. 15-3=12.

we have 12. this must equal 12!!!!!

Answer:

50

Step-by-step explanation:

180-130=50

Answer:

105

Step-by-step explanation:

first part: put them equal to each other

6x - 25 + 4x = 45 + 3x - 7

10x - 25 = 38 + 3x

7x - 25 = 38

7x = 63

x = 9

second part: plugin

6x - 25 + 4x

6(9) - 25 + 4(9)

54 - 25 + 36

29 + 36

= 65

-- plugging this in one of the equation is enough, since both are the same.

final answer for the second part: 65

Answer:

8) y = x/2 + 6

9) x = -(7/4)

Step-by-step explanation:

for (8), start with point-slope form and enter -2, 5, and 1/2 into the appropriate places:

y-5 = (1/2)(x- -2)

simplify by distributing (1/2)

y-5 = x/2 + 1

add 5 to both sides to get yourself in slope-intercept form

y = x/2 + 6

for 9, start by distributing the 3 and the 2

6x-12 = 10x-8+3

combine like terms

6x-12 = 10x-5

subtract 6x from both sides

-12 = 4x-5

add 5 to both sides

-7=4x

divide both sides by 4

-(7/4) = x

Answer:

The length of the box is (x + 1)

The height of the box is (x + 1)

Step-by-step explanation:

The given function representing the volume of the box is presented as follows;

V = x³ + 6·x² + 9·x + 4

The function representing the width of the box, W = x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1

x³ + 4·x²

    [tex]{}[/tex]  2·x² + 9·x + 4

    [tex]{}[/tex]  2·x² + 8·x

    [tex]{}[/tex]               x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)

The width of the box = (x + 4)

The length of the box = (x + 1)

The height of the box = (x + 1).

Answer:

  1) see below

  2) 2.5 inches per day

  3) the seed was planted below ground level

  4) h = 2.5d -3

Step-by-step explanation:

1) We note that the seedling grew 12-7 = 5 inches in the 2 days between day 4 and day 6. This lets us fill in the numbers for even days by adding or subtracting 5 inches:

  day 8 will be 5 inches more than day 6, 17 inches.

  day 2 will be 5 inches less than day 4, 2 inches.

  day 0 will be 5 inches less than that, -3 inches.

The value for day 3 will be halfway between day 2 and day 4, so will be (2+7)/2 = 4.5 inches.

See the attachment for the complete table.

__

2) In one day, the plant grows in/day = 5/2 = 2.5 inches.

__

3) If the plant grows at the steady rate of 5 inches in 2 days, it must have been planted 3 inches below ground on day 0.

__

4) In question 2, we found the rate per day (slope) to be 2.5. In question 3, we found the "y-intercept" to be -3. Then the slope-intercept equation with independent variable d and dependent variable h is ...

  h = 2.5d -3

Step-by-step explanation:

as we know

law of cosine

[tex]c = \sqrt{ {a}^{2} + {b}^{2} - 2ab. \cos(c) } [/tex]

[tex]c = \sqrt{ {14}^{2} + {18}^{2} - 2.14.18 - \cos( {35}^{o} ) } [/tex]

[tex]c = 10.35[/tex]

using the law of cosine

[tex]cos(a) = \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} [/tex]

[tex] \cos(a) = \frac{ {18}^{2} + {10.35 }^{2} - {14}^{2} }{2.18.(10.35)} [/tex]

[tex]a = {50.87}^{o} [/tex]

b=87.13°

m = 4/5 for the perpendicular line

m = -5/4 for the parallel line

y = -5/4x + 3

for the line above, m = -5/4

The line parallel to this line would have exactly the same slope m =  -5/4

The line perpendicular to this line would have a  slope equal the inverse with the opposite sign  

m = -5/4

So m = (1/(5/4)) is the slope of the m for the perpendicular line

m = 4/5
