Answer:

√15

Step-by-step explanation:

Assuming that it is:

$15^\frac{1}{2}$

Exponent rule for fractional exponents are:

$x^\frac{a}{b}=\sqrt[b]{x^a}$

Apply rule:

$15^\frac{1}{2}=\sqrt{15}$

Hope this helps!

briana house is at (1,6) and jordan house is(5,3) what is one possible path from brianna house to jordan house

Maurinko [17]

Answer:

see the explanation

Step-by-step explanation:

Let

A (1,6)------> location Brianna's house on a map

B (5,3)------> location Jordan's house on a map

we know that

One possible path from Brianna's house to Jordan's house it's a straight line ( the shortest distance)

using a graph tool

see the attached figure

<em>Find the distance points AB</em>

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$d_A_B=\sqrt{(3-6)^{2}+(5-1)^{2}}$

$d_A_B=\sqrt{(-3)^{2}+(4)^{2}}$

$d_A_B=\sqrt{25}$

$d_A_B=5\ units$

The distance from Brianna's house to Jordan's house is 5 units

tossing a number cube numbered from 1 to 6 and getting an Evan number that is greater than of equal to 2

photoshop1234 [79]

Even numbers on die: 2,4,6
odd numbers on die: 1,3,5
3+3=6 -> 6 numbers in total
3/6 chance because there are 3 even numbers. This would round to 1/2, so 1/2 a chance the die will roll an even number.

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 9 inches, a width of 3 inches, and a h

Over [174]

Answer:

$Area = 138in^2$

Step-by-step explanation:

Given

$L = 9; W =3; H =3\frac{1}{2}$

Required

The surface area

This is calculated as:

$Area = 2(LW + LH + WH)$

So:

$Area = 2(9*3 + 9*3\frac{1}{2} + 3*3\frac{1}{2})$

$Area = 2(27 + 31\frac{1}{2} + 10\frac{1}{2})$

$Area = 2*69$

$Area = 138in^2$

A. The slope of the curve y=x^3- 1 at the point P(1,0) is<br> .

Ierofanga [76]

Answer:

Step-by-step explanation:

The measure of the slope is $\frac{dy}{dx}$ at x = a

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x³ - 1, then

$\frac{dy}{dx}$ = 3x²

The slope at (1, 0) is

$\frac{dy}{dx}$ = 3(1)² = 3

A circle has a radius of 3. An arc in this circle has a central angle of 60. What is the length of the arc ?

Mashutka [201]

This is the formula:

Arc length = 2(3.14)(3)(60/360)

18.84(60/360)

18.84 x 0.16 = 3

The length of the arc = 3
