Answer:

<u>The equator has the length:</u>

  • C = 2πr, where π = 22/7, r = 6400 km
  • C = 2*22/7*6400 = 40228.57 km (rounded)

a) Consider X and Y as two points on the circle with C = 40228.57 km.

<u>The distance between X and Y is:</u>

  • d = C*(123 - 67)/360
  • d = 40228.57*56/360 = 6257.78 km (rounded)

b) Since both X and Y are on the equator, they are at the same distance from the north pole, N.

<u>NX makes 90 degrees:</u>

  • NX = C*90/360
  • NX = 40228.57*1/4 = 10057.14 km (rounded)

Answer:

-2x^2-20x-46

Step-by-step explanation:

-2(x^2)-20x-46

-2(x^2) -2(10x)-46

-2(x^2)-2(10x)-2(23)

-2(x^2+10x)-2(23)

Answer:

Solving the expression  \frac{\sqrt[3]{7} }{\sqrt[5]{7} } we get \mathbf{7^{\frac{2}{15}}}

Option D is correct option.

Step-by-step explanation:

We need to solve the expression: \frac{\sqrt[3]{7} }{\sqrt[5]{7} }

We know that

\sqrt[3]{x}=x^{\frac{1}{3} and \sqrt[5]{x}=x^{\frac{1}{5}

<u>Using above rule:</u>

<u />\frac{\sqrt[3]{7} }{\sqrt[5]{7} }\\=\frac{7^{\frac{1}{3}}}{7^{\frac{1}{5}}}<u />

Now, we know the exponent rule if bases are same and divided then exponents are subtracted i.e:  \frac{a^m}{a^n}=a^{m-n}<u />

Using the exponent rule

=7^{\frac{1}{3}-\frac{1}{5}  }\\Simplifying\:exponents\\=7^{\frac{5-3}{15}}\\=7^{\frac{1*5-1*3}{15}}\\=7^{\frac{2}{15}}

So, solving the expression  \frac{\sqrt[3]{7} }{\sqrt[5]{7} } we get \mathbf{7^{\frac{2}{15}}}

Option D is correct option.
