1 answer:
Aleonysh [2.5K]3 years ago

Answer:

x=5

Step-by-step explanation:

First, let's understand logarithms.

When there is no base given, like in this problem's right side of the equation, the base is automatically 10.

So, let's re-write that.

\frac{7}{x+2}=log_{10}x+5

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.

\frac{7}{5+2}  =log_{10}(5+5)\\\frac{7}{7} =  log_{10}(10)\\1 = 1

What is tan C ?
MatroZZZ [7]

Answer:

\frac{1}{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC of the figure, the tangent of angle C is equal to divide the opposite side to angle C (side AB) by the adjacent side to angle C (side BC)

so

tan(C)=\frac{AB}{BC}

substitute the given values

tan(C)=\frac{11}{22}

simplify

tan(C)=\frac{1}{2}

How do I find dis?<br> 180 rotation about the point (1,4)
prohojiy [21]

Answer:

When we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).

Step-by-step explanation:

We know that 180 Degree Rotation.

We know that when we rotate a point, let say P(x, y), 180 degrees counterclockwise about the origin, the coordinates of point P(x, y) transformed to P'(-x, -y).

In other words, the sign of both x and y coordinates are reversed.

Thus, the rule is:

P(x, y) → P'(-x, -y)

Given the point (1, 4)

P(x, y) → P'(-x, -y)

A(1, 4) → A'(-1, -4)

Thus, when we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).
