Answer:

$6.73 \times {10}^{ - 8}$

Step-by-step explanation:

7.4 × 10 ^-8 - 6.7 × 10^-9

= 7.4 × 10^-8 - 0.67 × 10^-8

= (7.4 - 0.67) × 10^-8

= 6.73 × 10^-8

Find the volume of a right circular cone that has a height of 12 cm and a base with a diameter of 18 cm.

algol [13]

Answer:1017.36 cm^3

Step-by-step explanation:

Diameter=18cm

Radius=r=18/2=9cm

Height=h=12cm

Volume of cone=1/3 x π x r^2 x h

Volume of cone=1/3 x 3.14 x 9^2 x 12

Volume of cone=1/3 3.14 x 9 x 9 x 12

Volume =(1x3.14x9x9x12) ➗ 3

Volume =3052.08 ➗ 3

Volume =1017.36

Volume of cone=1017.36 cm^3

Given m with arrow = 3 î + 2 ĵ − 5 k and n with arrow = 6 î − 2 ĵ − 4 k, calculate the vector product m with arrow ✕ n with arro

erastovalidia [21]

We know that for two vectors u and v we have that the cross product is equal to : (u2v3 - u3v2) i + (u3v1 - u1v3) j + (u1v2 - u2v1) k Then we have that m x n : ( (2 *-4) - (-5 * -2) ) i + ( (-5*6) - (3 *-4) )j + ( ( 3*-2) - (2*6))k which becomes ( -8 - 10) i + ( -30 + 12) j + ( -6 - 12) k Thus the vector product of m and n is -18 i - 18j -18k

The graph of quadratic function f has zeros of -8 and 4 and a maximum at (-2,18). What is the value of a in the function’s equat

Gennadij [26K]

<h2>Quadratic Function Equations</h2>

To find the equation of a parabola given the vertex and the zeroes, we can use the intercept form equation to help us:

$y=a(x-r)(x-s)$

r and s = intercepts/zeros of the graph

<h2>Solving the Question</h2>

We're given:

Zeros: -8, 4
Maximum: (-2, 18)

$y=a(x-r)(x-s)$

⇒ Plug in the given information:

$y=a(x-(-8))(x-4)\\18=a(-2-(-8))(-2-4)\\18=a(-2+8)(-2-4)\\18=a(6)(-6)\\18=a(-36)\\1=-2a\\\\a=-\dfrac{1}{2}$

<h2>Answer</h2>

$a=-\dfrac{1}{2}$

3*(x-1)/4 + 1 < x-2/3

ICE Princess25 [194]

Answer: x>11/3

Step-by-step explanation:

Let's solve your inequality step-by-step.

Step 1: Simplify both sides of the inequality.

Step 2: Subtract x from both sides.

Step 3: Subtract 1/4 from both sides.

Step 4: Multiply both sides by 4/(-1).

The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot , where S is the speed in kilometers

zalisa [80]

Answer:

0.32km

Step-by-step explanation:

The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot , where S is the speed in kilometers per hour and d is the average depth of the water in kilometers.

This is written mathematically as:

S = 356√d

What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour?

S = 200km/hr

Hence:

200km/hr = 356√d

Divide both sides by 356

200/356 = 356√d/356

√d = 200/356

Square both sides

(√d)² = (200/356)²

d =(0.5617977528)²

d = 0.3156167151km

Approximately = 0.32km
