Solve for t: F =2t+k/3g

Solve the following equation or inequality for the unknown variable. Round answer to two decimal places if necessary.

Sonbull [250]

Answer:

x = 2.7

Step-by-step explanation:

The given equation is :

$(3x)^2-10=56$

We need to solve it for x.

It can be rewrite as follows:

$9x^2-10=56$

Adding 10 to both sides,

$9x^2-10+10=56+10\\\\9x^2=66\\\\x=\sqrt{\dfrac{66}{9}}\\\\x=2.70$

So, the value of x is equal to 2.7.

Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation

Mariana [72]

Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.

I am trying to figure this question: <br><br> 1 + tan^2A = Sec^2A

chubhunter [2.5K]

Answer:

see explanation

Step-by-step explanation:

Using the Pythagorean identity

cos²A + sin²A = 1 ( divide terms by cos²A )

$\frac{cos^2A}{cos^2A}$ + $\frac{sin^2A}{cos^2A}$ = $\frac{1}{cos^2A}$ , that is

1 + tan²A = sec²A ← as required
