Shane marched 3 m East and 6 m north. How far is he from his starting point. Round your answer to the nearest tenth.

Dennis_Churaev [7]

Answer:

The distance from his starting point is 6.7 m.

Step-by-step explanation:

Given:

Shane marched 3 m East and 6 m north.

Now, to get the distance from his starting point.

Let the distance from the starting point be $x.$

Now, to solve using pythagorean theorem:

$AB^2+BC^2=AC^2$

$6^2+3^2=x^2$

$36+9=x^2$

$45=x^2$

Using square root on both sides we get:

$6.71=x\\\\x=6.71\ m.$

So, the distance from the starting point nearest to tenth is 6.7 m.

Therefore, he is 6.7 m from his starting point.

The height of water shooting from a fountain is modeled by the function f(x) = −4x2 + 24x − 29, where x is the distance from the

Komok [63]

Answer:

the maximum height of the water is 7 ft

Step-by-step explanation:

Using " ^ " to indicate exponentiation, we have −4x^2 + 24x − 29.

Rewrite -4x^2 + 24x as -4(x^2 - 6x) and then complete the square of (x^2 - 6x). We get:

(x^2 - 6x + 9 - 9), which is exactly equivalent to (x^2 - 6x).

Going back to the original equation: −4x^2 + 24x − 29, or

−4(x^2 - 6x) − 29.

Now replace (x^2 - 6x) with (x^2 - 6x + 9 - 9):

-4(x^2 - 6x + 9 - 9) - 29, which simplifies to:

-4(x - 3)^2 + 36 - 29, or

-4(x - 3)^2 + 7, whose vertex is (3, 7). Thus, the maximum height of the water is 7 ft.

Douglas bought a new sports car for $34,900 plus tax on the car tax was 9.95% what was the total price of the car include??

nata0808 [166]

To find the car tax, you first have to convert 9.95% to a decimal not a percentage. To do this, you move the decimal 2 places to the left to get 0.0995. Then you multiply 0.0995 by 34,900 (because it is 0.0995 of the car price) to get $3,472.55. This is the car tax in dollars. Finally, you add $3,472.55 to the car price of $34,900 to get a total price of $38,372.55.
