Log10 (x squared - 4x + 7) = 2

1 answer:

6 0

Log_(10)(x² - 4x + 7) = 2

Take the base 10 anti log of both sides.
x² - 4x + 7 = 10² = 100
x²- 4x - 93 = 0

Quadratic Formula
x = [4 ± √(4²-4(1)(-93))]/[2(1)] = [4 ± 2√97)]/2 = 2 ± √97

What is the perimeter of the figure in the diagram (round to three decimal places if necessary)? A) 54.5 B) 42.634 C) 39.5 D) 27

beks73 [17]

Answer:

Step-by-step explanation:

First add all the simple line up so;

$8 + 7 + 3 + 2 = 20$

Then use Pythagoras to work out the lengths of the remaining lines

$\sqrt{ {2}^{2} + {4}^{2} } = 2 \sqrt{5} \\ \sqrt{ {3}^{2} + {1}^{2} } = \sqrt{10} \\ 20 + \sqrt{10} + 2 \sqrt{5} = 27.63441362$

So to three decimal places it would be;

$27.634$

Addition Property of Equality
Subtraction Property of Equality

Terms/Coefficients

Step-by-step explanation:

*Note:

When dividing or multiplying both sides of the inequality by a negative, flip the inequality sign.

Step 1: Define

Identify.

4 - 5g > 39

Step 2: Solve for g

[Subtraction Property of Equality] Subtract 4 on both sides: -5g > 35
[Division Property of Equality] Divide -5 on both sides: g < -7

∴ any number g less than -7 would work as a solution to the inequality.
