Answer:

Given :  A toy car is placed on the floor. Its movement details are given

To find : Distance covered by Car & graph to be plotted

Solution:

Start from rest

u = 0  at  t = 0

Constant acceleration for 3 sec reaching velocity 4 m/s

V = U +at

=> 4 = 0 +  a(3)

=>a = 4/3  m/s²

Distance here  S = ut + (1/2)at²

S = 0 + (1/2)(4/3)3²

=> S = 6 m

deceleration of 0.5 m/s² for 4 sec

=> v = 4  - (0.5)4

=> v = 2 m/s

Distance here   =  4(4)  - (1/2) (0.5)4²

= 16 - 4

= 12 m

Total Distance = 6 + 12 = 18 m

Total Distance traveled by toy Car = 18 m

Answer:

$ 4,500.00

Step-by-step explanation:

I = $ 4,500.00

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

I = 10000 × 0.09 × 5 = 4500

I = $ 4,500.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 9% per year

for 5 years is $ 4,500.00.

I believe 72 years

Step-by-step explanation:

it has to be twenty characters so this to make it long enough

Answer:

12 years

Step-by-step explanation:

144,000.00 / 2,000.00 is 72 times that he deposited 2,000.00 in order to get 144,000.00.  If he deposits once every 2 months then he would have deposited 72 months x 2.  That is 144 months he took to deposit that much.  144 / 12 months in a year is 12 years.  He takes 12 years to save 144,000.00.

Answer:

$143

Step-by-step explanation:

Step-by-step explanation:

Answer:

9a + 5b + 4 is written as a sum of three terms, 4 is a constant, 9a is a coefficient.

Step-by-step explanation:

A coefficient is the number before a letter. In some cases it would be the number you either multiply or divide by another number. A constant is a single number that either isn't changed or is added or subtracted by another coefficient (alone) . A term is just a mathematical expression used in math. It is either just a normal equation or a big expression like this one. You also cant add or subtract 9a by 5b or 4 because in order to to do that 5b or 4 has to have an "a" at the end~example- instead of 5b it would have to be 5a to subtract or add or do whatever . (has to be the same)

Answer:

Step-by-step explanation:

x - y² = -1     ⇒   - y² = - x - 1    ⇒    y² = x + 1   {x≥-1}

4x² + 9y² = 72

4x² + 9(x + 1)² = 72

4x² + 9(x² + 2x + 1) = 72

4x² + 9x² + 18x + 9 - 72 = 0

13x² + 18x - 63 = 0     ⇒   a = 13,  b = 18,  c = -63

[tex]x=\dfrac{-18\pm\sqrt{18^2-4\cdot13\cdot(-63)}}{2\cdot13}=\dfrac{-18\pm\sqrt{324+252}}{26}=\dfrac{-18\pm\sqrt{576}}{26}\\\\x=\dfrac{-18+24}{26}=\dfrac3{13}\qquad\vee\qquad x=\dfrac{-18-24}{26}=-\dfrac{21}{13}\\\\ y^2= x + 1\quad\iff\quad x\ge-1\\\\y^2=\dfrac3{13}+1\\\\ y^2=\dfrac{16}{13}\\\\y=\dfrac{4}{\sqrt{13}}=\dfrac{4\sqrt{13}}{13}\qquad\vee\qquad y=-\dfrac{4\sqrt{13}}{13}[/tex]

▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.

We know that :

[tex] =\tt {hypotenuse}^{2} = {leg}^{2} + {leg}^{2} [/tex]

Which means :

[tex] =\tt {15}^{2} + {x}^{2} = {18}^{2} [/tex]

[tex] =\tt 225 + {x}^{2} = 324[/tex]

[tex] =\tt {x}^{2} = 324 - 225[/tex]

[tex] = \tt {x}^{2} = 99[/tex]

[tex]\color{plum} =\tt x = 9.9 \: cm[/tex]

Thus, x (radius) = 9.9 cm

We know that :

[tex]\color{hotpink}\tt \: Surface \: area \: of \: cone \color{plum}=\pi r(r + \sqrt{ {h}^{2} + {r}^{2} } [/tex]

Then, the surface area of this cone :

[tex] = \tt3.14 \times 9.9 \times( 9.9 + \sqrt{ {15}^{2} + {9.9}^{2} } )[/tex]

[tex] =\tt 3.14 \times 9.9 \times( 9.9 + \sqrt{323.01} )[/tex]

[tex] =\tt 3.14 \times 9.9 \times (9.9 + 18)[/tex]

[tex] =\tt 3.14 \times 9.9 \times 27.9[/tex]

[tex] = \tt31.09 \times 27.9[/tex]

[tex]\color{plum} =\tt\bold{ 867.4 \: cm}[/tex]

Therefore, the surface area of this cone = 867.4 cm

The 6 faces of a cube have equal are.

Each face has are of 5*5=25 because they are all squares.

Now we just multiply by 6

25*6=150 centimeters cubed.

Done!

Step-by-step explanation:

step 1. a cube had 6 sides

step 2. each side is a square

step 3. the area of each side is 5x5 = 25cm^2

step 4. the surface area of the cube is 25x6 = 150cm^2.

Answer:
