What is the value of x? Enter your answer, as a decimal, in the box. m Image shows triangle M P N with midsegment A B where A is
igor_vitrenko [27]

Applying BPT theorem in triangle MNP, which states that, If a line is drawn parallel to one side of a triangle intersecting other two sides, then it divides the two sides in the same ratio.

\frac{MB}{BP}=\frac{MA}{AN}

\frac{x}{96.6-x}=\frac{80.5-35}{35}

\frac{x}{96.6-x}=\frac{45.5}{35}

35x= 45.5(96.6-x)

35x= 4395.3 - 45.5x

80.5x = 4395.3

x=54.6 meters

Find the simple interest on the following hint I = prn
likoan [24]

Answer:

960

Step-by-step explanation:

I=PRN

I=4000(6%)(4)

You first want to convert your 6% to a decimal, you do so by dividing. 6/100= 0.06. Now you multiply to find your interest.

I=4000(0.06)(4)

I=4000(0.24)

I=960

Tom, Larry, Roberta, and John enjoy roller Coasters. Whenever a new roller Coaster opens near their town,
vazorg [7]

Answer:

  • <u>a) degree 3</u>
  • <u>b) 3 times</u>
  • <u>c) cubic</u>

<u></u>

Explanation:

The function that represents the first drop of the roller coaster is:

       h(t)=t^3-12t^2+35t,

where t is the  time in seconds and h is the height in feet.

<u></u>

<u>a) What is the degree of the function?</u>

The degree of a polynomial is the highest power of the variable, t. Thus, the degree of the function is 3.

<u>b) According to the degree of the function, how many times should the roller coaster hit the ground?</u>

The number of complex roots of a polynomial is equal to the degree of the polynomial. Thus, in this case this polynomial has 3 roots. Each root represents the value of the polynomial that makes it equal to zero, this is:

     t^3-12t^2+35t=0

Thus, since the polynomial function represents the height of the, the value zero represents when the roller coaster hits the ground.

To learn if the three roots are real numbers you can solve the equation, which may be done by factoring the polynomial.

Take t out as common factor:

  • t(t² - 12t + 35)

Find two numbers that add up -12 and its product is 35. Those are -7 and -5. Hence, use the factors t - 12 and t - 5:

  • t ( t - 12) (t - 5) = 0  This is the factored form of the polynomial

Whose solutions are t =0, t = 12, and t = 5. Three real numbers.

Hence, the roller coaster hits the ground three times: first at start, then  at 5 seconds, and finally at 12 seconds.

<u>c) Will the roller coaster be in the form of a linear, quadratic, cubic or quartic graph?</u>

It will be in the form of a cubic graph, becasue a linear graph corresponds to a polynomial of degree 1, a quadratic graph corresponds to a polynomial of degree 2, a cubic graph corresponds to a polynomial of degree 3, and a quartic graph corresponds to a polynomial of degree 4.

HELPPPP <br><br>which value is equal to 2✓28-5✓63?<br><br>a-37✓7<br>b-✓7<br>c-11✓7<br>d✓7​
IrinaVladis [17]

Answer:

c

Step-by-step explanation:

if I understand this right, then the expression is

2×sqrt(28) - 5×sqrt(63)

let's look for squared factors in the numbers under the square roots.

28 = 4×7 (4 is a squared number)

63 = 9×7 (9 is a squared number)

so,

2×sqrt(4×7) - 5×sqrt(9×7) =

= 2×2×sqrt(7) - 5×3×sqrt(7) = 4×sqrt(7) - 15×sqrt(7) =

= (4 - 15)×sqrt(7) = -11×sqrt(7)
