Hey!

---------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4)

---------------------------------------------------------------------

Question 6:

= 5ac - 2b

= 5(-3)(5) - 2(2)

= 5(-15) - 4

= -75 - 4

<u>= -79</u>

---------------------------------------------------------------------

Question 7:

= ab/d

= (-3)(2)/-4

= -6/-4

<u>= 1 1/2</u>

---------------------------------------------------------------------

Hope this helped, good luck!

A triathlon requires participant to complete the following tasks:
Lesechka [4]

Answer:

Step-by-step explanation:

Time taken for task 1:

Distance= 750m= 0.75 km

Speed= 10 km/hr

Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec

Time taken for task 2:

t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec

Time taken for task 3:

t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec

Total time took:

T1 +T2+T3= 40 mins and 30 second (approximately)

Use the Remainder Theorem to determine which of the roots are roots of F(x). Show your work.
Brums [2.3K]

Answer:    x1=1   x2=-2  and x3=2

Step-by-step explanation:

1st   x1=1 is 1 of the roots , so

F(1)=1-1-4+4=0 - true

So lets divide x^3-x^2-4x+4 by (x-x1), i.e  (x^3-x^2-4x+4) /(x-1)=(x^2-4)

x^2-4 can be factorized as (x-2)*(x+2)

So x^3-x^2-4x+4=(x-1)*(x^2-4)=(x-1)(x-2)*(x+2)

So there are 3 dofferent roots:

x1=1   x2=-2  and x3=2

jolli1 [7]

Question:

The quantities x and y are proportional.

x\ \ \ \ \ \ \ \ \ \ y \\1\frac{2}{9}\ \ \ \ \ \ \ 2\frac{1}{3}

Find the constant of proportionality (r)

Answer:

r = 1\frac{10}{11}

Step-by-step explanation:

Given

x\ \ \ \ \ \ \ \ \ \ y \\1\frac{2}{9}\ \ \ \ \ \ \ 2\frac{1}{3}

Required

Determine the constant of proportionality (r)

Constant of proportionality (r) is calculated as

y = rx

When

y = 2\frac{1}{3}       x = 1\frac{2}{9}

Substitute these values in the given formula

2\frac{1}{3} = r * 1\frac{2}{9}

Convert both fractions to improper fractions

\frac{7}{3} = r * \frac{11}{9}

Multiply both sides by \frac{9}{11}

\frac{7}{3} * \frac{9}{11}= r * \frac{11}{9} * \frac{9}{11}

\frac{7}{3} * \frac{9}{11}= r

Reorder

r = \frac{7}{3} * \frac{9}{11}

r = \frac{7 * 9}{3 * 11}

Divide the numerator and denominator by 3

r = \frac{7 * 3}{11}

r = \frac{21}{11}

Convert to mixed fraction

r = 1\frac{10}{11}

<em>Hence, the constant of proportionality is </em>1\frac{10}{11}<em></em>
