Step-by-step explanation:

A = money market account

B = stocks

C = mutual fund

A + B + C = 269,100

0.031A + 0.04B - 0.02C = 3,180

B = 10,000 + C (we will first replace B)

A + 10,000 + C + C = 269,100

A + 2C = 259,100

0.031A + 0.04(10,000 + C) - 0.02C = 3,180

0.031A + 400 + 0.04C - 0.02C = 3,180

0.031A + 0.02C = 2,780

A + 2C = 259,100

-100(0.031A + 0.02C) = -100 · 2,780

A + 2C = 259,100

-3.1A - 2C = -278,000

-2.1A = -18,900

A = -18,900 / -2.1 = $9,000

C = (259,100 - 9,000) / 2 = $125,050

B = $125,050 + $10,000 = $135,050

Answer:

Step-by-step explanation:

Step one:

given

time= 2.5 hours

speed= 6.3mph

Step two:

Required

Distance

we are given the speed in miles per hour, hence the distance will be in miles

we also know that the expression relating speed, distance and time is given as

speed= distance/time

thus

distance= speed*time

distance= 6.3*2.5

distance= 15.75 miles

By using expression for the speed, distance traveled by me in 2.5 hours will be  

Given in the question,

Expression for the speed of an object is given by,

Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

Therefore, Distance = Speed × Time

By substituting the values of speed and the time in the expression,

Distance traveled = 6.3 × 2.5

                              =  15.75 miles

   Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

Answer:

The horizontal distance the ball travels before it hits the ground is 22.[tex]\overline{857142}[/tex] feet

Step-by-step explanation:

The given parameter are;

The function modelling the path of the ball tossed by Nate y = -14·x² + 335·x

x = The horizontal distance the ball travels from Nate in feet

y = The height of the ball in feet

The line equation modelling the hill is y = 15·x

The point where the ball hits the ground is given by the point the graph of the equation for the path of the ball and the path of the model of the line of the hill meet as follows;

Ball path is y = -14·x² + 335·x

Hill path is y = 15·x

The point both paths meet and the ball hits the ground is -14·x² + 335·x = 15·x

Which gives;

-14·x² + 335·x - 15·x = 0

-14·x² + 320·x = 0

320·x - 14·x² = 0

x × (320 - 14·x) = 0

x = 0, or x = 320/14 = 22 6/7 = 22.[tex]\overline{857142}[/tex] feet

Therefore;

The horizontal distance the ball travels before it hits the ground = x = 22.[tex]\overline{857142}[/tex] feet.

The path of ball will be parabolic in nature .Parabolic path is defined as the angle of trajectory of a projectile.

Ball travel 22.86 feet horizontally before it hits the ground.

Since, The path of the ball is modeled by the function [tex]y = -14x^{2} + 335x[/tex]

where x is the ball’s horizontal distance from Nate in feet and y is the ball’s height in feet.

And hill is modeled by equation, [tex]y=15x[/tex]

To find out how much ball will travel horizontally before it hits ground , we have to find intersection of given two model equation.

[tex]y = -14x^{2} + 335x[/tex]

[tex]y=15x[/tex]

So,  [tex]-14x^{2} + 335x=15x\\\\-14x^{2} + 335x - 15x = 0\\\\320x - 14x^{2} = 0\\\\x(320-14x)=0\\\\x=0, x=320/14=22.86[/tex]

Thus, Ball travel 22.86 feet horizontally before it hits the ground.

The expression that is equal to 2sin(π/10)cos(π/10) is sin(π/5).

The correct option is C.

The sine function in trigonometry is the ratio of the hypotenuse's length to the opposite side's length in a right-angled triangle. To determine a right triangle's unknown angle or sides, utilize the sine function.

Given that the expression is 2sin(pi/10)cos(pi/10).

The expression can be rewritten as 2sin(π/10)cos(π/10).

Here, we can use the formula,

2sinAcosA = sin2A.

So, applying this formula to a given expression,

we get,

2sin(π/10)cos(π/10) = sin(2π/10)

Simplifying further, we get,

2sin(π/10)cos(π/10) = sin(π/5).

Therefore, the required expression is sin(π/5).

Answer:

[tex]\frac{-9}{12}[/tex]

Step-by-step explanation:

First, we need to isolate y.

1. Subtract 12x from both sides.

-9y=-12x+135

2. Divide by -9 in order to isolate y.

[tex]y=\frac{12}{9} x-15[/tex]

3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].

Answer:answer y  =  337.5

Step-by-step explanation:

y varies directly with x,  so  y = kx   , where  k  is some constant.

y  =  kx        When  y = 75 ,  x = 1/2 .   So

75  =  k(1/2)       Multiply both sides by  2 .

150  =  k

y  =  150x

To find  y  when  x = 2  , plug in  2  for  x .

y  =  150( 2 )        1/4 = 0.25 ,  so  2 + 1/4 = 2.25

y  =  150( 2.25 )

y  =  337.5

Answer:

the answer is [tex]27[/tex]

Step-by-step explanation:

First, you need to substitute a, b, and c for their sums

So your new problem should look like this... [tex]2+\left(3-\left(-2\right)\right)^2[/tex]

Then you can begin solving this problem using PEMDAS

So first you're going to start w/ the parenthesis... [tex]3-\left(-2\right)[/tex] which equals 5

Next, you're going to calculate the exponents, so it should look like this... [tex]5^{2}[/tex] which equals [tex]25[/tex]

So now your problem should look like this... [tex]5+25[/tex] which equals [tex]27[/tex]

So your answer is [tex]27[/tex]

The roots are located at (2,0) and (4,0)

In short, the roots are x = 2 and x = 4

The term "x intercept" is another way of saying "root". Both describe the location where the graph crosses the x axis.

Answer:

(2,0) and (4,0)

Step-by-step explanation:

Hello!

The roots of the parabola are the coordinates where the graph intersects the x-axis (y = 0).

As you can see, the vertex of the graph is above the x-axis, and opens down, meaning that there are two roots for the graph.

Points of intersection:

Therefore, the coordinates of the roots are (2,0) and (4,0).
