Answer:

7.071inches

Step-by-step explanation:

The set up is a right angled triangle

Given 'angle of elevation = 45 degrees

The length of the frame = 10in (hypotenuse)

Required

Height of the truck h (opposite)

Using the SOH trig identity

sin theta = opposite/hyp

sin 45 = h/10

h = 10sin45

h = 10(0.7071)

h = 7.071 in

Hence the height of the truck is 7.071inches

Step-by-step explanation:

let's say number of patches is x, and amount of time is y. the time per patch is k.

k * x = y

2 * k = 4

k = 2

2 * x = y

2 * 6 = 12

Answer:

i think its 2

Step-by-step explanation:

The equation of  x² + 6x + y² - 8y = 19 in standard form is (x + 3)² + ( y - 4)² = 44. Hence, Option A is the correct answer.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have been given the equation as;

x² + 6x + y² - 8y = 19

We need to find the standard form of the equation.

Thus, we have,

(x²  + 6x )+(y²- 8y) = 19

We shall complete the square for the term;

(x²  + 6x + 9 - 9 ) + (y² +  4y + 16 - 16) = 19

Simplifying, we get,

(x²  + 6x + 9) - 9 + (y²- 8y + 16) - 16 = 19

(x²  + 6x + 9) - 9 + (y²- 8y + 16) - 16 = 19 + 9 + 16

Formula used :

x²+2xy+y² = (x+y)²

x²-2xy+y² = (x-y)²

Simplifying, we get,

(x + 3)² + ( y - 4)² = 44

Thus, the equation of  x² + 6x + y² - 8y = 19 in standard form is (x + 3)² + ( y - 4)² = 44.

Hence, Option A is the correct answer.

Answer:

0.1039

Step-by-step explanation:

Obtain the place value of 9 in each value and choose the smallest :

1.95

9 is the first digit after the decimal point ; which is equal to 0.9 = tenth place

0.1039

9 is the 4th digit after the decimal point ; which is equal to 0.0009 = ten thousandth place

3.092

9 is the second digit after the decimal point ; which is equal to 0.09 = hundredth place

2.009​

9 is the third digit after the decimal point ; which is equal to 0.009 = thousandth place

Hence the smallest value of 9 among the options given resides in 0.1039 (ten thousandth place).

Answer:

25 presents.

Step-by-step explanation:

First subtract 2.7(4) from 30.

30 - 2.7(4) = 19.2 meters

Now, convert 19.2 into centimeters.

There's 100cm in 1m, so 19.2 meters can be found by doing:

19.2 x 100 = 1920 cm.

Now, do 1920 divided by 75:

1920/75 = 25.6

Since you can't tie 0.6 of a present, you disregard that. So, she can tie 25 presents.

[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]

Step-by-step explanation:

When given at least two points, you can find write an equation using the point-slope formula: [tex]y - y_1 = m (x - x_1)[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values from one point that need to be substituted in to make an equation, as well as the [tex]m[/tex] which represents the slope.

Find the slope by using the slope formula [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] and the two points given:

[tex]\frac{-1-0}{6-3}[/tex]

[tex]\frac{-1}{3}[/tex]

So, the slope is [tex]-\frac{1}{3}[/tex].

Next, choose a point (in this case, I chose (3,0)) and substitute its x and y values into [tex]x_1[/tex] and [tex]y_1[/tex] respectively, and also substitute  [tex]-\frac{1}{3}[/tex] for m. This forms an equation of a line in point-slope formula:

[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]

Point Form:

( − 7 , − 10 )

Equation Form:

x = − 7, y = − 10

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

y = -10

Step-by-step explanation:

4x - 4y = 12

Substitute the x with -7, since it has been given.

4(-7) - 4y = 12

-28 - 4y = 12

Add 28 onto both sides

-28 + 28 - 4y = 12 + 28

-4y = 40

Divide by -4 to isolate the variable

-4y/-4 = 40/-4

y = - 10

Check:

Substitute the y and x

4x - 4y = 12

4(-7) - 4 ( -10 ) = 12

-28 + 40 = 12

12 = 12

or.....

try to see if x stays as -7

4x - 4y = 12

4x - 4 (-10) = 12

4x + 40 = 12

Subtract 40 onto both sides

4x + 40 - 40 = 12 - 40

4x = -28

Divide by 4 onto both sides to isolate the variable

4x/4 = -28/4

x = -7

And it's correct

Hope this helped!
