Answer:

The scores are as follows:

Caroline Castways = 72

Raleigh Rockets = 24

Step-by-step explanation:

Let c be the Castways score and r be the Raleigh Rocket’s score

Then

According to given statements, the equations will be:

[tex]c+r = 96\\r = \frac{1}{3}c[/tex]

From equation 2

[tex]3r=c[/tex]

Putting c = 3r in equation 1

[tex]3r+r = 96\\4r = 96\\\frac{4r}{4} = \frac{96}{4}\\r = 24[/tex]

Putting the value of r in equation 2

[tex]r = \frac{1}{3}c\\24 = \frac{1}{3}c \\c = 24*3\\c = 72[/tex]

Hence,

The scores are as follows:

Caroline Castways = 72

Raleigh Rockets = 24

Answer:

cos a = -1.28 and 0.78

Step-by-step explanation:

The question is not properly written. This is the correct question:

If sina×tan(a) = 1/2, find cosa

According to trigonometry identity;

tan a = sina/cosa

sina×tan(a) = sin a * sina/cosa

sin²a/cos a = 1/2

(1-cos²a)/cosa = 1/2

Cross multiply

2(1-cos²a) = cos a

2 - 2 cos²a = cos a

2cos²a + cos a - 2 = 0

Let P = cos a

2P² + P -2 = 0

P = -1 ±√1-4(2(2)/2(2)

P =  -1 ±√1+16/4

P = -1 ±√17/4

P = -1±4.12/4

P = -1-4.12/4 and -1+4.12/4

P = -5.12/4 and 3.12/4

P = -1.28 and 0.78

Since P = cos a

Hence cos a = -1.28 and 0.78

Answer:

D) (0,1) (2,3) (4,5)

Step-by-step explanation:

Explanation

Given Points are  A(0,1) , B(2,3) , C(4,5)

slope of the AB

                  [tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{3-1}{2-0} =\frac{2}{2} =1[/tex]

Slope of BC

                [tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-3}{4-2} =\frac{2}{2} =1[/tex]

Therefore slope of AB and BC are equal

The three points lie on same straight line

The three points are collinear points

Answer:

a = 1

Step-by-step explanation:

The important point here is that both lines are horizontal reflections of each other. If we treat the line x = a as a kind of "mirror" for these lines, every point at the same y value on each line is going to be an equal horizontal distance from that "mirror". If that's confusing, think about how, as you pull your hand away from a mirror, your hand's reflection seems to go deeper into it. As you bring it closer, your reflection gets closer too. And when you're touching the mirror, it seems like your hand and its reflection are touching!

We want to find that "touching" point for the two lines, the intersection, because it'll tell us exactly where our "mirror" - more commonly called the axis of symmetry - is. The point of intersection of any two lines is the point where their equations are exactly equal to each other.

Our equations are y = 3x - 5 and y = 1 - 3x, so setting those two equal to each other and solving for x:

[tex]3x-5=1-3x\\6x=6\\x=1[/tex]

This tells us that the two lines intersect at x = 1, which is exactly our axis of symmetry, so a = 1!

Answer:

x=3

y=1

Step-by-step explanation:

We know that y is basically two less than x, so we can plug that into the second equation:

x+ (x-2) = 4

We can now simplify:

2x-2=4

2x=6

x=3

After finding x we can now find y with any equation (both work):

y= 3-2

y=1

Answer:error

Step-by-step explanation:

An expression is combination of variables, numbers and operators. The factor of expression 0.15c-0.072  is 0.15(c-0.48)

An expression is combination of variables, numbers and operators.

The given expression is

zero point one five times of c minus zero point zero seven two.

Expression 0.15c-0.072

A factor is a number that divides another number, leaving no remainder.

0.15c-0.072

Let us take 0.15 common

0.15(c-0.48)

Hence the factor of expression 0.15c-0.072  is 0.15(c-0.48)
