Answer:

Step-by-step explanation:

This problem is solved using the Pythagorean theorem  (a2+b2=c2).  In this formula a and b are the legs of the right triangle while c is the hypotenuse.

Using the labels of our triangle we have:

o2+a2=h2

\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}

h2=100ft2+289ft2

h=389ft2−−−−−√

So with this information you can see that the correct answer is 19.7ft

The slope of the given graph x^2 = ln (xy) at the point (1, e) is e

We have been given a graph x^2 = ln (xy) and a point (1, e)

Differentiate the given graph on both sides

d/dx x^2 = d/dx (ln (xy))

⇒ 2x = 1/xy × d/dx (xy)

⇒ 2x × xy = x.dy/dx + y.dx/dx

⇒ 2x^2y = x.dy/dx + y

⇒  2x^2y = x.dy/dx + y

⇒ 2x^2y - y = x.dy/dx

⇒ (2x^2y - y)/x = dy/dx  … (1)

The slope at the point (1, e)

m = dy/dx at x = 1, y = e

Substitute the values in Equation (1)

⇒ m = (2(1)^2 (e) - e)/1

⇒ m = (2e - e)/1

⇒ m = e/1

⇒ m = e

Hence, the slope of the given graph is e.

Step-by-step explanation:

The cost of a soft taco is $1.25 and the cost of a burrito is $2.50.

Let the cost of a soft taco would be t and,

The cost of a burrito would be b

As per the given question, the equations would be as

3t+3b=11.25   ...(i)

4t+2b=10       ...(ii)

With the two equations in that form, an elimination solution is probably the simplest.

Multiply each equation by a constant so that the coefficients of b are opposite so that when the two equations are joined, b is eliminated.

-6t-6b = -22.50

12t+6b = 30.00

_____________

6t   =  7.50

t = 7.50/6 = 1.25

Substitute the value of t = 1.25 in equation (ii), and solve for b

4(1.25)+2b=10

5+2b=10

2b=5

b=2.50

Thus, the cost of a soft taco is $1.25 and the cost of a burrito is $2.50.

The probability of not spinning a 3 is 8/9

From the question, the given parameters are:

Number of sections = 9

Sections = Number 1 to 9

The probability of spinning a 3 = 1/9

The above probability can be represented as

P(3) = 1/3

The probability that the number 3 is not spun is the complement of the  probability of spinning a 3

This is calculated as

P(3) + P(Not 3) = 1

Substitute the known values in the above equation So, we have the following equation

1/9 + P(Not 3) = 1

Evaluate the like terms

P(not 3) = 8/9

Hence, the probability is 8/9

Step-by-step explanation:

Given an 8' object casts a 10' shadow, you want to know the length of the shadow of a 12' object.

The shadow length is proportional to the object length:

  shadow/object = 10'/8' = s/12'

Multiplying by 12', we have ...

  s = (12')(10/8) = 15'

The shadow of a tree 12 feet tall will be 15 feet long.

The missing expression in step 2 should be [(6² + 2)/0.5] - 14.8 ÷ 8.

The missing expression in step 6 should be 76 - 1.85.

In order to evaluate this expression, we would apply the PEMDAS rule, where mathematical operations within the parenthesis are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the expression to the right. Lastly, the mathematical operations of addition or subtraction would be performed from left to right.

For step 1, we have the following:

[(6² + 2)/|-0.5|] - 14.8 ÷ 8.

In step 2, we would take the absolute value of -0.5:

[(6² + 2)/0.5] - 14.8 ÷ 8.

Therefore, we would have the quantity of the sum of six squared (6²) plus two (2) divided by 0.25, minus 14.8 ÷ 8

In step 3, we would take the exponent of 6:

[(36 + 2)/0.5] - 14.8 ÷ 8.

In step 4, we would add 36 and 2 together:

[(38)/0.5] - 14.8 ÷ 8.

In step 5, we would divide 38 by 0.5:

76 - 14.8 ÷ 8.

In step 6, we would divide 14.8 by 0.5:

76 - 1.85

In step 7, we would subtract 1.85 from 76 as follows:

Solution = 76 - 1.85 = 74.15.

The strategy which would eliminate a variable in the system of equations is to multiply the top equation by -5 , then add the equation and is denoted as option B.

This is a mathematical term which is made up of two expressions and is connected by an equal sign.

In the example given below:

x - 2y = 11

5x + 3y = -11

We can multiply the top by -5 which will result in:

-5x + 10y = -55 after which it is added to the other to give:

-5x + 5x + 10y + 3y  = -55 + (-11)

13y = -66

y = -66/13.

From this we can notice that the variable x was eliminated which is why option B is the correct choice.

The equation that models the function is y = 8/3(x) - 5/3.

Given:

The graph of a linear function passes through the point (-2, -7).

When the input increases by 3 the value of the function increases by 8.

(x,y) = (x+3,y+8)

(-2,-7) = (-2+3,-7+8)

= (1,1)

slope between (1,1) and (-2,-7) is m = -7-1/-2-1

= -8/-3

m = 8/3.

substitute m in y = mx + c

y = 8/3(x)+c

substitute (-2,-7)

-7 = 8/3(-2) + c

-7*3 = -16 + 3c

-21+16 = 3c

-5 = 3c

c = -5/3

y = 8/3(x) - 5/3.

Therefore the equation that models the function is y = 8/3(x) - 5/3.
