Answer 1

Answer:

Approximate maximum height is 5 ft

[tex]h(\frac{18}{32} )= 5 \ ft[/tex]

Step-by-step explanation:

[tex]h(t)=-16t^{2} + 18t[/tex]      ---------- (1)

Differentiate equation (1)  w.r.t t and equate it to zero (in order to determine maxima)

[tex]h^{'}(t) = -32t+18[/tex]

[tex]0= -32t+18[/tex]

[tex]t=\frac{18}{32}[/tex]

Substitute this value in equation (1)

[tex]h(\frac{18}{32} )=-16(\frac{18}{32} )^{2} + 18(\frac{18}{32} )[/tex]

[tex]h(\frac{18}{32} )=-5+ 10[/tex]

[tex]h(\frac{18}{32} )= 5 \ ft[/tex]

Sue started the day with $260 in her bank account.She purchased 15 books that we're all the same price.After she left the store,she had -$10 in her account.How much did each book cost?

Answers

Answer:

$18

Step-by-step explanation:

Since she ended up with -$10 in her account after leaving the store, that means that she spent $270 at the store total.

Since the books were the same price, just divide.

270/15=18

This means that each book cost $18

The graphs with the equation 3y + x = 1/2 and 9y - 21x = -621/10 have been drawn on the grid.

Answers

Answer:

X= 2.61

Y= -0.7

Step-by-step explanation:

The estimates of the solutions of the simultaneous equations given are x = 2.65 and y = -0.71.

Given a graph of the two equations:

3y + x = 1/2

9y - 21x = -621/10

These simultaneous equations can be solved and find the solution algebraically by substitution or elimination methods.

Here, it is required to find the solution using the graphs.

Already, the graphs of the two equations are given.

The solution of the two equations graphically can be found by the intersecting point of those graphs.

Here the two graphs intersect at :

x value in between 2.6 and 2.7.

y value close to -0.7.

So the solution can be estimated as x = 2.65 and y = -0.71.

OAB is a sector of a circle with centre O and radius 8 cm.
Angle AOB = e°
The area of the sector is 58 cm2
Calculate the perimeter of the sector.
Give your answer correct to 3 significant figures.

Answers

Answer:

The perimeter of the sector is :30.5 cm

Step-by-step explanation:

Mathematically, we have the area of the sector as;

e/360 * pi * r^2

r is 8 cm

so we have

58 = e/360 * pi * 8^2

58/64 * 360/pi = e

e = 103.85

To get the perimeter,

we have length of the arc plus 2r

Length of the arc is;

e/360 * 2 * pi * r

add 2 r;

e/360 * 2 * pi * r + 2r

so we have

103.85/360 * 2 * pi * 8 + 2(8)

= 14.5 + 16

= 30.5 cm

The slope of the line is
_____m/s.

Answers

Given:

The graph of a line which represents position (m) at time (s).

To find:

The slope of the line.

Solution:

Formula for slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given graph it is clear that the line passes through two points (0,0) and (1,4).

Using the above formula, we get

[tex]m=\dfrac{4-0}{1-0}[/tex]

[tex]m=\dfrac{4}{1}[/tex]

[tex]m=4[/tex]

Therefore, the slope of the line is  4 m/s.

I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a
