Tasya [4]

Answer:

Hey boss man, just add up all the sides! For example, just add 3.9+3.9+3.9! and if there is a line in the middle of a certain side, it means that it is congruent or the same as another side with a dash. For example, with number 2, the side without a measurement is congruent with the the side with measurement of 7mm! Hope this helps! You got this! :)

If 4^x+1 = 64, then what is the value of x^4
Olin [163]
4^{x} + 1 = 64 \\4^{x} = 63 \\ln(4^{x}) = ln(63) \\xln(4) = ln(63) \\x = \frac{ln(63)}{ln(4)}

(\frac{ln(63)}{ln(4)})^{4} = 79.78006702

The value of x⁴ is equal to 79.8006702

F(x) = 3x^2 +12x+7 in standard form
ivann1987 [24]

Answer:

y = ax^2 + bx + c  =>  F(x) = 3x^2 +12x+7;   F(x) = 3x^2 +12x+7 is already in standard form for the equation of a parabola.

Step-by-step explanation:

Actually, F(x) = 3x^2 +12x+7 is already in standard form, y = ax^2 + bx + c.  Double check the instructions for this problem.  Did you perhaps want "vertex form?"

The equation of a circle is (x-2) squared + (y-6) squared =64. What is the center and radius of the circle.
evablogger [386]

Answer:

The center (2,6) and the radius is 8

Step-by-step explanation:

The equation of a circle is (x-h)^2 + (y-k)^2 =r^2

where (h,k) is the center of the circle and r is the radius

We have

(x-2)^2 + (y-6)^2 =64

(x-2)^2 + (y-6)^2 =8^2

The center (2,6) and the radius is 8
