Find the value of c such that the equation x^2 - c = 0 has 12 and –12 as solutions.
Sonbull [250]

Answer:

c=144

Step-by-step explanation:

The given equation is x^2-c=0

If this equation has 12 and -12 as roots, then the roots must satisfy the equation.

We substitute x=12 to obtain

12^2-c=0

144-c=0

Solve for c to get:

144=c

This implies that:

c=144

We could have also substitute x=-12 to get the same result.

Suppose that
Diano4ka-milaya [45]

Answer:

sin(B) = 12/13

cos(B) = 5/13

tan(B) = 12/5

csc(B) = 13/12

sec(B) = 13/5

cot(B) = 5/12

Step-by-step explanation:

If ABC is a right triangle, assuming that ∠C = 90°, then the segment AB =13 is the hypotenuse and the other two sides are:

BC = 5\\AC = \sqrt{13^2 - 5^2}\\AC = 12

The six  trigonometric functions of angle B are:

sin(B) =\frac{AC}{AB}= \frac{12}{13}\\cos(B) = \frac{BC}{AB} =\frac{5}{13}\\tan(B) = \frac{AC}{BC} =\frac{12}{5}\\\csc(B) =\frac{1}{sin(B)}= \frac{13}{12}\\sec(B) = \frac{1}{cos(B)} =\frac{13}{5}\\cot(B) = \frac{1}{tan(B)} =\frac{5}{12}\\

In the figure, AB = 15.8, 11.9 10.2, 8.4 inches and AC = 18.7, 15.5, 14.3, 13.1 inches.
TEA [102]
Tan=oposite/adjacent=AB/BC
tan(40)=AB/10
10tan(40)=AB≈8.391
so AB=8.4

use pythagorean theorem to find the hypotnhuse

reemember
a²+b²=c²
so
10²+8.4²=c²
100+70.56=c²
170.56=c²
sqrt both sides
13.0599=c so 13.1


AB=8.4 inches
AC=13.1 inches
