Answer:

The length of the hypotenuse ≈ 39.7 cm

Explanation:

Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.

The equation for Pythagorean calculation is:

(hypotenuse)² = (first leg)² + (second leg)²

In the given, we have:

first leg = 30 cm

second leg = 26 cm

Substitute with the givens in the above equation to get the hypotenuse as follows:

(hypotenuse)² = (30)² + (26)²

(hypotenuse)² = 1576

This means that:

either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted

or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative

Hope this helps :)

Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

$f(x) = 2x^3 - 3x^2 - 18x - 8$

Substituting x = 2 in the above function,

We get,

$f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8$

$=2(8) - 3(4) - 36 - 8$

$=16 - 12 - 44$

$\implies f(2)= -40$

Hence, the value of f(2) would be -40.

7 3/10 as a percentage

Harlamova29_29 [7]

7 3/10 in percent would be $7.3 \times 100 = 730$ %

730%

percent means over 100

So... 730% = 730/100 = 7.3

Complete Question

The complete question is shown on the first uploaded image

Answer:

The score of the student is x = 779.42

Step-by-step explanation:

Generally we can mathematically represent the z-score as

$z = \frac{x - Mean}{ stDev}$

Here x is the score of the student

substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have

$-1.2 = \frac{x - 1045.7 }{ 221.9}$

=> $-266.28 = x -1045.7$

=> x = -266.28 + 1045.7

=> x = 779.42
