we are given the following triangles:

We are asked to determine the value of "y". To do that we will use the tangent of 25:

\tan 25=\frac{y}{x}

We solve for "y" by multiplying both sides by "x":

x\tan 25=y

Now, we take the tangent of 15:

\tan 15=\frac{y}{30+x}

Now, we solve for "y" by multiplying both sides by the denominator:

(30+x)\tan 15=y

Now, we set both values of "y" equal, we get:

x\tan 25=(30+x)\tan 15

now, we solve for "x". First, we apply the distributive property on the right side:

x\tan 25=30\tan 15+x\tan 15

Now, we substract

Solve the equation 1.5y < -6.75
finlep [7]
1.5y < -6.75

First, divide both sides by '1.5'.
\frac{-6.5}{1.5}
Second, since 4.5 × 1.5 = 6.5, simplify the fraction to '-4.5'
y \ \textless \  -4.5

Answer: y < -4.5

Given the recursive function f(n) = f(n - 1) - 3 ; f(1) = 9 , what would be the first three terms of the sequence ?
Ann [662]

The first three terms of sequence are 9 , 6 , 3

<em><u>Solution:</u></em>

Given the recursive function f(n) = f(n - 1) - 3

Where f(1) = 9

To find: First three terms of sequence

Substitute n = 2 , n = 3 and n = 4 in given recursive function

When n = 2

f(n) = f(n - 1) - 3

f(2) = f(2 - 1) - 3

f(2) = f(1) - 3

f(2) = 9 - 3 = 6

f(2) = 6

Thus second term is 6

When n = 3

f(3) = f( 3 - 1) - 3

f(3) = f(2) - 3

f(3) = 6 - 3 = 3

f(3) = 3

Thus the third term is 3

When n = 4

f(4) = f( 4 - 1) - 3

f(4) = f(3) - 3

f(4) = 3 - 3

f(4) = 0

Thus the fourth term is 0

Thus first three terms of sequence are 9 , 6 , 3

Rosa is converting a unit of measure in one system to a unit of measure in another system (1, 760yd)/(1mj) * (0.914m)/(1yd) * (1
Murljashka [212]

Answer:

The statement about Rosa's calculations that is true is (0.914m)/(1yd).

Step-by-step explanation:

The ratio of meter (m) to yard (yd) is 0.914 : 1.

Therefore, the conversion factor is 0.914 m/1 yd
