Answer:

Step-by-step explanation:

Given

Height H = 4 feet

Velocity = 14ft/s

Required

Time the pumpkin will hit the ground

Using the equation of mottion

H = ut + 1/2gt²

4 = 14t + 1/2(9.8)t²

4 = 14t + 4.9t²

4.9t²+14t-4 = 0

t = -14±√196+16(4.9)/2(4.9)

t = -14±√196+78.4/2(4.9)

t = -14±16.57/9.8

t = -14+16.57/9.8

t = 2.57/9.8

t = 0.2seconds

Drag the tiles to the correct boxes to complete the pairs Match each inequality to the number line that represents its solution

Anna [14]

Answer:

x ≤ 7 => $- \frac{13x}{18}$ + $\frac{5}{9} \geq - \frac{9}{2}$

x ≤ 8 => - $\frac{x}{10}$ + $\frac{1}{5}$ ≥ - $\frac{33}{55}$

x ≤ -5 => - $\frac{50x}{3}$ - $\frac{11}{6}$ $\geq$ $\frac{163}{2}$

x ≤ -6 => $\frac{3x}{2}$ + 105 ≤ 96

Step-by-step explanation:

- $\frac{x}{10}$ + $\frac{1}{5}$ ≥ - $\frac{33}{55}$

$\frac{1}{5}$ + $\frac{33}{55}$ ≥ $\frac{x}{10}$ / *10

2 + 6 ≥ x

8 ≥ x

- $\frac{50x}{3}$ - $\frac{11}{6}$ $\geq$ $\frac{163}{2}$ / *6

- 100x - 11 ≥ 489

-500 ≥ 100x

-5 ≥ x

$\frac{3x}{2}$ + 105 ≤ 96

$\frac{3x}{2}$ ≤ 96 - 105 / * $\frac{2}{3}$

x ≤ -6

$- \frac{13x}{18}$ + $\frac{5}{9} \geq - \frac{9}{2}$ /*18

-13x + 10 ≥ - 81

-13x ≥ -91 /:-13

x ≥ 7

What is the solution to the inequality in interval notation? |4x+6|≤14

alexandr1967 [171]

Answer: x>5

Step-by-step explanation: The Absolute Value term is |4x+6|

For the Negative case, we'll use -(4x+6)

For the Positive case, we'll use (4x+6)

-(4x+6) = 14

Multiply

-4x-6 = 14

Rearrange and Add up

-4x = 20

Divide both sides by 4

-x = 5

Multiply both sides by (-1)

x = -5

Which is the solution for the Negative Case

(4x+6) = 14

Rearrange and Add up

4x = 8

Divide both sides by 4

x = 2

x=-5

x=2

The average grain of salt is 0.0003 meters wide. Rhinovirus, which causes the common cold, is 0.00000003 meters wide. How many t

algol [13]

Answer:

$1\times 10^4\ times$

Step-by-step explanation:

Given:

Width of average grain of salt is, $w=0.0003\ m$

Width of Rhinovirus is, $W=0.00000003\ m$

Now, expressing each width in scientific notation form, we get:

$w=0.0003\ m = 3\times 10^{-4}\ m\\\\W=0.00000003\ m = 3\times 10^{-8}\ m$

Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,

$\frac{W}{w}=\frac{3\times 10^{-4}\ m}{3\times 10^{-8}\ m}\\\\\frac{W}{w}=1\times 10^{-4-(-8)}=1\times 10^{-4+8}=1\times 10^4\\\\\therefore W=1\times 10^4\times w$

Therefore, the grain of salt is $1\times 10^4\ times$ wider than Rhinovirus.
