What are the solutions to log (x² + 8) = 1 +logo(x)?
Answers
Answer:
x = 9.125 and 0.875
Step-by-step explanation:
Given the expression
log (x² + 8) = 1 +log(x)?
This can also be written as;
log (x² + 8) = log 10 +logo(x)
log (x² + 8) = log(10x)
(x² + 8) = (10x)
x² -10x + 8 = 0
Factorize;
x = 10±√(-10)²-4(8)/2
x = 10±√100-32/2
x = 10±√68/2
x = 10±8.25/2
x = 10+8.25/2 and 10-8.25/2
x = 18.25/2 and 1.75/2
x = 9.125 and 0.875

Unit 1: Geometry Basics Homework 3: Angle Relationships
Answers
Answer:
juicy no no square
Step-by-step explanation:
The value of x = z = 73 degrees and y = 107degrees
3) Geometry is a branch of mathematics that deals with the measurement of lines and angles.
From the diagram shown, we can see that the two lines intersect at a point. The following is therefore true:
y = 107° (vertically opposite angle)The sum of z and 107 is supplementary. Hence;
z + 107 = 180z = 180 - 107z = 73degreesAlso, the sum of x and y is also supplementary. This shows that:
x + y = 180x + 107 = 180x = 180 - 107x = 73dgreesFrom the calculations, hence x = z = 73 degrees and y = 107degrees

Answers
Answer:
20 adults and 10 children
Step-by-step explanation:
We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.
Answer:
10 children 20 adults
Step-by-step explanation:
children = c
adult = 2c (double than children)
2(c) + 4(2c) = 100
10c = 100
c = 10 10 children
30-10 = 20 20 adults
$2(10) = $20
$4(20) = $80
$20+$80 = $100

Step-by-step explanation:
In order to solve this question, we need to subtract the smaller area of the hole from the bigger area of the actual donut. We use the formula [tex]a=\pi r^2[/tex]. We plug the numbers in for the smaller circle and the area of the smaller circle is 3.14. Then, we plug in the numbers for the bigger number and we get 28.27. We subtract 3.14 from 28.27 and we get approximately 25, which is equal to J.

Answer:

Step-by-step explanation:
HF is a perpendicular bisector of Δ EGH
Then Δ EGH is an isosceles triangle with 2 congruent sides GH and EH , so
GH = EH
3x - 8 = 2x ( subtract 2x from both sides )
x - 8 = 0 ( add 8 to both sides )
x = 8
Then
GH = 3x - 8 = 3(8) - 8 = 24 - 8 = 16
Answer:
From diagram, FG = EF
Solving fo HF and FG by Pythagorean Theorem
HF² = (3x -8)² -FG²
HF² = (2x)² -FG²
We can eliminate HF² and FG² from BOTH equations because they cancel out.
The 2 equations become (3x -8)² = (2x)²
9x² -48x +64 = 4x²
5x² -48x +64 = 0
Using Quadratic Formula
X1 = 8
X2 = 1.6

Julie has basketball practice every 6 days and track practice every 4 days. In how many days will she have both basketball and track practice
Answers
Answer: 12 days
Step-by-step explanation:
For us to know the number of days whereby Julie will have both basketball and track practice, we've to find the lowest common multiple of both 6 and 4. This will be:
Multiples of 4 = 4, 8, 12, 16, 24.
Multiples of 6 = 6, 12, 18, 24, 30.
The lowest common multiple is 12. Therefore, she'll have basketball and track practice in 12 days

According to question, X+7=2Y
20+Y=4X
X=2Y-7 (from 1st condition)
putting in it second
20+Y=4(2Y-7)
20+Y=8Y-28
20+28=8Y-Y
48=7Y
Y=48/7
so X=2(48/7)-7

A dog runs 100 yards from one corner of a rectangular park to the opposite corner. If the length of the park is 28 yards, what is the width?
Answers
9514 1404 393
Answer:
96 yards
Step-by-step explanation:
The diagonal through the park cuts the rectangle into two right triangles. The Pythagorean theorem tells you the relationship between the sides of a right triangle and its hypotenuse: the sum of the squares of the sides is equal to the square of the hypotenuse.
The diagonal is the hypotenuse, so we have ...
100² = 28² + w²
w = √(10000 -784) = 96
The width of the park is 96 yards.
_____
Additional comment
The integer side lengths of a right triangle form what is called a "Pythagorean triple." One of the most often seen of these is (3, 4, 5). Other commonly seen Pythagorean triples are (5, 12, 13), (7, 24, 25), (8, 15, 17).
You may notice that the numbers here are those of the (7, 24, 25) Pythagorean triple, multiplied by 4. If you recognize the given lengths as having the ratio 28:100 = 7:25, you have the clue you need to determine the answer simply from your knowledge of Pythagorean triples.
1/2b-7=5.5 slove for b
Answers
Answer:
b = 25
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] b - 7 = 5.5 ( multiply through by 2 to clear the fraction )
b - 14 = 11 ( add 14 to both sides )
b = 25
Answer:
B=25
Explanation1
1/2b−7=5.5
Add 7 to both sides.
1/2b=5.5+7
b=5.5+7
Add 5.5 and 7 to get 12.5.
1/2 b=12.5
Multiply both sides by 2, the reciprocal of 1/2.
b=12.5×2
Multiply 12.5 and 2 to get 25.
b=25
