Jaime knows that 30² is 900. He wonders if knowing that 30² can help him finds 29x31. Raquel knows what 25² equals. How can she

Answer:

Jaime: yes: 29·31 = 900 -1 = 899

Raquel: 24·26 = 25^2 -1 = 624

Step-by-step explanation:

The difference of squares factors as the product of the sum and difference of the roots:

a^2 -b^2 = (a -b)(a +b)

<u>Jaime</u>

29·31 = (30 -1)(30 +1) = 30^2 -1^2 = 900 -1 = 899

Jaime can subtract 1 from 30^2 to find 29·31

<u>Raquel</u>

24·26 = (25 -1)(25 +1) = 25^2 -1^2 = 625 -1 = 624

Raquel can subtract 1^2 from 25^2 to find 24·26.

The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express

ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

$x+x\times \frac{13.6}{100}=57$

$x+0.136x=57$

$1.136x=57$

Divide both the sides by 1.136.

$\frac{1.136x}{1.136}=\frac{57}{1.136}$

$x=50.176$

$x\approx 50$

Therefore the number of cases prior to the increase is 50.

Find tan0, cos0, and csc0, where 0 is the angle shown in the figure. Give exact values, not decimal approximations. BRANLIEST!!

Setler [38]

Answer:

see explanation

Step-by-step explanation:

We require to find the third side of the triangle.

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x represent the third side, then

x² + 15² = 17², that is

x² + 225 = 289 ( subtract 225 from both sides )

x² = 64 ( take the square root of both sides )

x = $\sqrt{64}$ = 8

Thus

tanΘ = $\frac{opposite}{adjacent}$ = $\frac{15}{8}$

cosΘ = $\frac{adjacent}{hypotenuse}$ = $\frac{8}{17}$

sinΘ = $\frac{opposite}{hypotenuse}$ = $\frac{15}{17}$

cscΘ = $\frac{1}{sin0}$ = $\frac{1}{\frac{15}{17} }$ = $\frac{17}{15}$
