What is the value of x in the equation 25x^2=16? A.+ 5/4 B.+4 C.+ 4/5 D.+16/25

4vir4ik [10]

Answer:

x = ± 4/5

Step-by-step explanation:

25 x^2 = 16

Divide each side by 25

25 x^2 /25 = 16 /25

x^2 = 16 /25

Take the square root of each side

sqrt(x^2) = ±sqrt(16/25)

We know that sqrt(a/b) = sqrt(a)/ sqrt(b)

x = ±sqrt(16) / sqrt(25)

x = ± 4/5

Help find missing segment??

AleksandrR [38]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Let x as the missing segment.

_________________________________

According to the Thales theorem :

$\frac{26}{x} = \frac{12}{36} \\$

$\frac{26}{x} = \frac{12}{12 \times 3} \\$

$\frac{26}{x} = \frac{1}{3} \\$

Inverse both sides

$\frac{x}{26} = \frac{3}{1} \\$

$\frac{x}{26} = 3 \\$

Multiply sides by 26

$26 \times \frac{x}{26} = 26 \times 3 \\$

$x = 26 \times 3$

$x = 78$

Thus the missing segment has a measure of 78 .

Dovator [93]

$\large \underline{ \mathbb{QUESTION:}}$

The lifeguard of the beach resort is on his post which is 4 m high. A boy in the pool is 9 meters away from him. Find the angle of depression from the lifeguard to the boy.

$\large\underline{ \mathbb{ANSWER \: \& \: SOLUTION:}}$

$\large \tt{ tan \: x \: = \: \frac{opposite}{adjacent} }$

$\large \tt{tan \: x \: = \: \frac{4}{9}}$

$\large \tt{ \: \: \: \: \: \: \: \: x \: = \: tan ^{ - 1} \: (0.444)}$

$\large \tt {\: \: \: \: \: \: \: \: x \: = \: 23.96 ^{o} }$

$\:\:\:\:\:\:\:\: \large \boxed{\tt{\red{ x \: = \: 24 ^{o} }}}$

Therefore the angle of depression from the lifeguard to the boy is 24°.
