Answer:

x=− 9 /4

​or  

=−2.250

Step-by-step explanation:

Answer:

The Answer is 2

EXPLANATION:

y(x)=2x+3

y(x+Δx)=2(x+Δx)+3

=2x+2Δx+3

Δy=y(x+Δx)−y(x)

=(2x+2Δx+3)−(2x+3)

=2Δx

⇒Δy=2Δx,  Δy/Δx =2

The rate of change in the equation of a line in slope-intercept form

y = 2x + 3 is 2.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An equation of a line y = 2x + 3.

This is in slope-intercept y = mx + b, where 'm' is the slope.

Therefore, The rate of change in y = 2x + 3 is 2.

Step-by-step explanation:

Answer:

7mph and he stayed the same

Step-by-step explanation:

Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same, 7 mi/hr, he maintained a constant speed throughout this period.

Given that Larry recorded his time as he ran

Time elapsed(hr)         Distance run(mi)

     2                                       13.5

     4                                       27.5

     7                                       48.5

We need to calculate his average speed,

To calculate Larry's average speed, we need to divide the total distance he ran by the time elapsed.

Let's calculate his average speed from hour 2 to hour 4 and from hour 4 to hour 7:

Average speed from hour 2 to hour 4:

Distance covered = 27.5 mi - 13.5 mi = 14 mi

Time elapsed = 4 hr - 2 hr = 2 hr

Average speed = Distance covered / Time elapsed = 14 mi / 2 hr = 7 mi/hr

Therefore, Larry's average speed from hour 2 to hour 4 was 7 miles per hour.

Average speed from hour 4 to hour 7:

Distance covered = 48.5 mi - 27.5 mi = 21 mi

Time elapsed = 7 hr - 4 hr = 3 hr

Average speed = Distance covered / Time elapsed = 21 mi / 3 hr = 7 mi/hr

Therefore, Larry's average speed from hour 4 to hour 7 was also 7 miles per hour.

Since Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same (7 mi/hr), he maintained a constant speed throughout this period. He neither sped up nor slowed down.

Answer:

40 ft

Step-by-step explanation:

The maximum height of the ball is the y- coordinate of the vertex

Given a parabola in standard form then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

h(t) = - 16t² + 48t + 4 ← is in standard form

with a = - 16, b = 48 , thus

[tex]x_{vertex}[/tex] = - [tex]\frac{48}{-32}[/tex] = 1.5

Substitute t = 1.5 into h(t) for max. height

h(1.5) = - 16(1.5)² + 48(1.5) + 4

         = - 36 + 72 + 4

          = 40

Answer:

14

Step-by-step explanation:

[tex] - 98 = - 7h \\ \\ - 98 \div - 7 = h \\ \\ 14 = h[/tex]

Answer:

A = $1,650.24

Step-by-step explanation:

A = P(1 + r/n)^nt

Where

A = future value

P = present value = $1,600

r = interest rate = 3.1% = 0.031

n = number of periods = 4

t = time = 1 year

A = P(1 + r/n)^nt

= 1,600( 1 + 0.031 / 4)^4*1

= 1600( 1 + 0.00775)^4

= 1600(1.00775)^4

= 1600(1.0314)

= 1,650.24

A = $1,650.24

The answer would be 8+4n

   y = x

b). Since, a circle has infinite lines of symmetry (diameters) so the other lines of symmetry of the given circle will be all infinite numbers of the diameters.

c). Other symmetry this circle has a point symmetry.
