qaws [65]

Step-by-step explanation:

S+24/7 = -2

7×{S +24/7} = -2×7

S+24 = -14

S+24-24 = -14-24

S = -38

The vertices of a triangle are A (0,0), B (3, 4) and C (-4,5). Find the length of each side. ​
Sphinxa [80]

Answer:

AB = 5 units

BC = 5\sqrt{2} units

AC = \sqrt{41} or about 6.4 units

Step-by-step explanation:

distance formula:  square root of the sum of the difference of the y-values and the difference of the x-values

ex, dAB = √(4-0)² + (3-0)²

              = √16 + 9

              = √25

              = 5

Draw a bar model that shows how the number of hours in March compares with the number of hours in February of this year.
gogolik [260]
Okay so first we need to find how many days are in March and February. March has 31 days and because this year was a leap year February has 29 days.

The next step is to convert days to hours.
March: 31x24=744
February: 29x24=696

Now its time to graph

Rewrite the expression with a rational exponent as a radical expression.
agasfer [191]

Answer:

The correct answer is B. \sqrt[9]{3}

Step-by-step explanation:

The root of a number can be expressed as the number raised to the power whose exponent is a fractional number. The exponent number will be the inverse of the root index.

In this case, three to the two thirds power all raised to the one sixth power is expressed as:

(3^{\frac{2}{3} }) ^{\frac{1}{6}}

Power of a Power Property: This property states that the power of a power can be found by multiplying the exponents.

So, we multiply the exponents:

\frac{2}{3} \times \frac{1}{6}= \frac{1}{9}

The expression would be:

3^{\frac{1}{9} }

which as a radical expression is:

\sqrt[9]{3}

The four options are expressed as:

a) \sqrt[6]{3}

b) \sqrt[9]{3}

c) \sqrt[18]{3}

d) \sqrt[6]{3^3}

The correct answer is B.

Work out the lengths of sides a and b.
alukav5142 [94]

The length of the missing sides of triangles A and B are 9.43 cm and 12.04 cm respectively.

<h3>Pythagoras theorem</h3>

Triangle A:

  • Height = 8cm
  • Base = 5cm
  • Hypotenuse = x cm

Hypotenuse² = height ² + base²

x² = 8² + 5²

= 64 + 25

x² = 89

x = √89

x = 9.43 cm

Triangle B:

  • Height = 12cm
  • Base = x cm
  • Hypotenuse = 17 cm

Hypotenuse² = height ² + base²

17² = 12² + x²

17² - 12² = x²

289 - 144 = x²

145 = x²

x = √145

x = 12.04 cm
