Answer:
-2.79, -4.21
Step-by-step explanation:
The function seen in the graph is 0.5 (x + 3.5)² - 1.
Hence,
[tex]0.5(x+3.5)^{2} -1=0\\0.5(x+3.5)^{2} =1\\(x+3.5)^{2} = 0.5\\x+3.5 = \sqrt{0.5}\\or\\ x+3.5=-\sqrt{0.5} \\[/tex]
Finding the first answer,
[tex]x+3.5=\sqrt{0.5} \\x=\sqrt{0.5}-3.5\\x=-2.79 (3sf)[/tex]
Finding the second answer,
[tex]x+3.5=-\sqrt{0.5}\\x=-\sqrt{0.5} -3.5\\x=-4.21(3sf)[/tex]

Solve for x in the following parallelogram. Show your work for full credit.
Work Shown:
S+R = 180
(4+9x) + (104) = 180
9x+108 = 180
9x = 180-108
9x = 72
x = 72/9
x = 8
Note: Adjacent angles of any parallelogram are supplementary, meaning they add to 180 degrees.
Without using a calculator evaluate:
- 81 + 203²
Step-by-step explanation:
multiply 203 by 200, you get 20300 and then multiply the 3 and you get 20909. Then subtract 81 from it and you have 20828 as the final answer.
Answer:
41128Step-by-step explanation:
This problem requires the formula "a² + 2ab + b²".
-81 + 203²=> -81 + (200 + 3)²=> -81 + (200² + 2(200)(3) + 3²)=> -81 + (40000 + 1200 + 9)=> -81 + (41209)=> 41209 - 81=> 41128Hence, 41128 is the answer without using calculator.

Answer:
The equation has no solution
Step-by-step explanation:
[tex]{ \tt{a + 5(2a - 1) + 3 = 11a - 2}} \\ { \tt{a + 10a - 5 + 3 = 11a - 2}} \\ { \tt{11a - 2 = 11a - 2}} \\ { \tt{11a - 11a = - 2 + 2}} \\ { \red{ \tt{0 = 0}}}[/tex]
Answer:
D, or Infinite Solutions
Step-by-step explanation:
We have the equation a + 5(2a - 1) + 3 = 11a - 2
Solve the equation and see if there's a solution or not.
a + 5(2a) - 5(1) + 3 = 11a - 2
a + 10a - 5 + 3 = 11a - 2
11a - 2 = 11a - 2
Since both equations are the same, then any value of a will satisfy the equation, making it have infinite solutions. Hope this helps.
The difference in Cameron and Avery’s ages is 5. The product of their ages is 104. If Cameron is older, how old is Avery?
Answer:
Cameron is 13 and Avery is 8 years oldStep-by-step explanation:
Let Cameron's age be x and Avery's age be y.
The difference is 5 and the product is 104:
x - y = 5xy = 104Solve by substitution:
x = y + 5xy = 104y(y + 5) = 104y² + 5y - 104 = 0y = (- 5 ± √(5² + 4*104))/2 = (- 5 ± √441)/2 = ( - 5 ± 21)/2Taking the positive root as age can't be negative:
y = 8Find x:

What are trigonometric functions?In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.
Given here: Height = 111 feet
Tan 5° = 111/base ⇒ base = 1268
Tan 15°=111/base-AB ⇒base-AB=414.25
AB=853.75
Hence, The distance between A and B is 853.75

Answer:
3^2=x+5
Step-by-step explanation:
The correct option is C - 3^2 =x+5
The equation is \log _{3}(x+5)=2
Option A: \log _{3}(x+5)=3^{2}
This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work out.
Option B: \log _{3}(x+5)=2^{3}
This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work either.
Option C: x+5=3^{2}
This is possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This works and It's equal
Option D: x+5=2^{3}
This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work also.
