Answer:

a=15, b=7, c=4

Step-by-step explanation:

we have

\sqrt[4]{15^{7}}

Remember that

\sqrt[c]{a^{b}}=a^{\frac{b}{c}}

so

\sqrt[4]{15^{7}}=15^{\frac{7}{4}}

therefore

a=15, b=7, c=4

Answer:

The solution, a=15, b=7 and c=4

Step-by-step explanation:

Given: \sqrt[4]{15^7}

using exponent and surds rule to change exponent to radical form or radical to exponent form.

Rule: \sqrt[n]{a^m}=a^{\frac{m}{n}}

Now we compare the given expression

\sqrt[n]{a^m}=\sqrt[4]{15^7}

\Rightarrow 15^{\frac{7}{4}}

It is equal to a^{\frac{b}{c}}

Compare both solution

a^{\frac{b}{c}}=15^{\frac{7}{4}}

a\rightarrow 15

b\rightarrow 7

c\rightarrow 4

Hence, The solution a=15, b=7 and c=4

A 10 foot ladder is leaning up against a building. If the ladder makes a 46° angle
Gnesinka [82]

Answer:

7.193 ft

Step-by-step explanation:

    |\

    |   \

    |      \

    |         \

h  |            \      10 ft

    |               \

    |                  \

    |            46°   \

    ---------------------

For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.

sin A = opp/hyp

sin 46° = h/10

h = 10 sin 46°

h = 7.193

Answer: 7.193 ft

Endpoint: (1,7), midpoint: (-10,10)
algol [13]

The answer is (-21, 13) for The second endpoint.  

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 1)/2 = -10

Kx + 1 = -20

Kx = -21

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + 7)/2 = 10

Ky + 7 = 20

Ky = 13

This gives us the final point of (-21, 13)
