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.
A boat is heading towards a lighthouse, whose beacon-light is 111 feet above the water. From point A, the boat's crew measures the angle of elevation to the beacon, 5º, before they draw closer. They measure the angle of elevation a second time from point B at some later time to be 15°. Find the distance from point A to point B. Round your answer to the nearest tenth of a foot if necessary.
Answer: 854.5
Step-by-step explanation:
I got it wrong so it gave me the explanation
The distance between A and B is 853.75
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:
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.
what are angles x and y
Answer:
y 79 x 79
Step-by-step explanation:
79 and y are equal because they are interior angles.
therefore y would be 79.
x and 79 are same side exterior angles. so x is 79 also

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.

Answer:

Step-by-step explanation:
First of all, let's name the top triangle n and the bottom one m, you can name them as you'd like.
okay, so, based on the Pythagorean theorem, a^2 + b^2 = c^2
now, we know that the area that is 12 units long, is equivalent to the hypotenuse of m, (it's very important that the bottom right angle is 90 degrees) and therefore, (5^2 = 25) 5^2 + ___ = 12^2 now let's solve that:
25 + _____ = 144 now just fill in the blank. With a simple subtraction, we get 119 (144 - 25 = 119), now remember, this is c^2 of m
and, 12+5=17 so, a of the n triangle is 17.
so let's put everything together: 17^2 + 119 = x^2
now, we're gonna calculate it: 17^2 = 289 and we're gonna add that to 119, so we get 408: 289 + 119 = x^2
But, this is x^2, and we want to find the value of x, so we have to find the square root of 408. Since we get a number with a lot of decimals in front of it, we're just gonna leave it as is, therefore the answer is √408

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:
