Answer: $1200 m$

$75\ m/min$

Step-by-step explanation:

Given

Alex Jogged 3 rounds of 400 m track

It took 16 min to Jog 3 rounds

(a) Total distance Alex had Jogged

$\Rightarrow 3\times 400=1200\ m$

(b) Average speed is the total distance by the total time

$\Rightarrow \dfrac{1200}{16}=75\ m/min$

Find the vertex of the graph of the function.<br> f(x) = 2x2 - 8x + 9

Katen [24]

Answer:

(2, 1).

Step-by-step explanation:

f(x)=2x^2-8x+9

Find -b/2a first, it's -(-8)/2(2)=8/4=2.

Then find the y-coordinate of the vertex.

2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1

The ratio of two complementary angles is 7:2. What is the measure, in degrees, of the larger angle?

lisabon 2012 [21]

Answer:

70 degrees

Step-by-step explanation:

Complementary angles sum up to 90.

To find the larger angle, you find the total of the values in the ratio, divide the larger value of the ratio by the total and multiply it by 90.

(7/7+2)×90=7/9×90

=7×10

=70

Write an equation:

7x+2x=90

9x=90

x=10

Then multiply x by the larger value.

7x=7 (10)=70

Answer:

The answer is 200.

Step-by-step explanation:

The steps are :

$\sqrt[3]{8 \times {10}^{6} }$

$= \sqrt[3]{8} \times \sqrt[3]{ {10}^{6} }$

$= {8}^{ \frac{1}{3} } \times {10}^{(6 \times \frac{1}{3} )}$

$= 2 \times {10}^{2}$

$= 200$
