<span>if exponent 2
4 • (2 + 5)^2 - 52
= </span>4 • (7)^2 - 52 
= 4 • 49 - 52
= 196 - 52
=  144

if multiply by 2
4 • (2 + 5)2 - 52 
= 4 • (7)2 - 52 
= 4 • 14 - 52
= 56 - 52
=  4

Consider the absolute value, because we only worry about the quadrant later.

\text{Consider: } sin(A) = |-\frac{\sqrt{3}}{4}|
sin(A) = \frac{\sqrt{3}}{4}

Thus, we know that the hypotenuse has a length of 4 units, and the side opposite the angle, A is √3, because this is the nature of the sine function in relation to its triangular component.

The missing side can be found using Pythagoras' Theorem:
4² - (√3)² = x²
16 - 3 = x²
13 = x²
x = √13

\therefore tan(A) = \pm \sqrt{\frac{3}{13}}

Since angle A is in the third quadrant, the tangent function will produce a positive angle.

tan(A) = \sqrt{\frac{3}{13}}
\text{Rationalise the denominator: } \frac{\sqrt{3}}{\sqrt{13}} \cdot \frac{\sqrt{13}}{\sqrt{13}}

tan(A) = \frac{\sqrt{39}}{13}

A set of mathematics exam scores are normally distributed with a mean of 80.280.280, point, 2 points and a standard deviation of
hichkok12 [17]

Answer:

0.3745

Step-by-step explanation:

Data

mean (\mu): 80

standard deviation (\sigma): 4

Normal distribution table is in figure attached .

Z = \frac{x - \mu}{\sigma&#10;}

Z = (85 - 80)/4 = 1.25

Area below curve = 0.3944

Z = (82 - 80)/4 = 0.5

Area below curve = 0.0199

Proportion of exam scores between 82 and 85?

0.3944 - 0.0199 = 0.3745

Please help ! I don’t get it!
Amiraneli [1.4K]

Answer:

PR = 16

SR = 12

Step-by-step explanation:

6/8 = (x-3)/(x+1)

8x-24 = 6x+6

simplify

2x = 30

x = 15

PR = 15 + 1 = 16

SR = 15 - 3 = 12
