In the triangle with legs 7 and 9 cm, you can find the length of the hypotenuse by using the Pythagorean theorem. If the hypotenuse is x, then

7^2+9^2=x^2\implies x=\sqrt{130}

The other right triangle with leg 6 cm and containing the angle \theta satisfies

\sin\theta=\dfrac{6\,\rm cm}{\sqrt{130}\,\rm cm}\implies\theta=\sin^{-1}\dfrac6{\sqrt{130}}\approx31.75^\circ

How to solve for probability
kirill [66]
Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2. Let's repeat the experiment of Example 1, with a die instead of a coin.

2.5d + 7.25 = 1 + 3.75d solve for d
dimulka [17.4K]

Answer:

5

Step-by-step explanation:

Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d

Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d

Divide 1.25 from both sides. You get 5 = d

zubka84 [21]

Answer:

y = 7/3 x + 2

Step-by-step explanation:

y = mx+b is the slope intercept form of a line

where m is the slope and b is the y intercept

Substituting in what we know

y = 7/3 x + 2

galina1969 [7]

Answer:

The error is in step 3. You cannot use a property of logarithms to prove that same property.

Step-by-step explanation:

Here we  the proof of the quotient rule as

If Logₐx = M and Logₐy = N

Then x = a^M and y = a^N

x ÷ y = a^M ÷  a^N = a^{(M-N)}

Take log of both sides we get

Logₐ(x÷y) = Logₐa^{(M-N)}

Logₐ(x÷y) =M-N logₐa

Logₐ(x÷y) =M-N

∴Logₐ(x÷y) = Logₐx - Logₐy
