Answer:
88
Step-by-step explanation:
The area of a triangle is calculated using the following formula:
1/2*b*h (b: base, h: height)
The height here is 11 and the base is 16
1/2*16*11 = 88 units square

5 and 8
2 and 3
Answer:
1 and 6
5 and 7
Step-by-step explanation:
Supplementary angles equal 180degrees. 1 = 60 and 6=120. 60+120=180.
5 = 60 and 7=120. 60+120=180

Put x=5f'(5):-
4(5)+920+929Option C
instantaneous rate can be found by differentiating the function.
Here,
f(x) = 2(x)² + 9(x)so differentiating:
f'(x) = d/dx (2(x)² + 9(x))f'(x) = 4(x) + 9So when x = 5,
f'(5) = 4(5) + 9f'(5) = 20 + 9f'(5) = 29This question has two parts. First, answer Part A. Then, answer Part B.

What is the value of x in the figure?
Enter your answer in the box.
x =
Answer:
29 is the correct answer because subtract 90 from 61 we get 29
Step-by-step explanation:
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASEAnswer:
29°
Step-by-step explanation:
We know that both angle x and angle "61°" add up to a sum of 90° because it is a right angle.
So, we would have to subtract 61 from 90 to find the missing value.
90 - 61 = 29
Therefore, x equals 29°

If tanx = 0.75, find the value of
i. cos2x + sin2x
2tanx
ii.
for 0° < x < 90°
C0Sx-sinx
-
Answer:
i. 31/25
ii. 1/5
Step-by-step explanation:
you know that tanx = 3/4, so you can also find that sinx = 3/5 and cosx = 4/5. Then you can use the double angle identities to find cos2x and sin2x: cos^2(x) - sin^2(x) + 2sinxcosx and substitute the givens to get 31/25. Then, cosx - sinx is obviously 1/5.

Find the area of the irregular figure.
Answer: 432 sq ft.
Step-by-step explanation: I decomposed the figure above into halves where the dotted line is drawn. I multiplied 25 x 10 to find the area of the rectangle on the right, pretending for now that it is a complete rectangle, which equals 250. Then, I subtracted 15 from 25, which equals 10, to find the length of the right triangle that’s missing to make the right half of the decomposed figure a rectangle. Then I multiplied 10 x 10, or 10 to the second power divided by 2 because 10 x 10 would be the formula to find a rectangle, and a right triangle is half of a rectangle so you would divide by 2. 10 x 10 divided by 2 because equals 50. 250 - 50 = 200. Next, you do the same thing for the other half of the irregular figure. I subtracted 4 from 25 to get 21. Then, I multiplied 21 x 16 divided by 2 which equals 168. Now, you multiply 25 x 16 which equals 400. 400 - 168 = 232. 200, the answer for the area of the other half of the decomposed figure, must be added to 232 to find your answer for the total area.

The table represents a linear function that shows the number of stamps y that a student collects after x months. Complete the table.
Answer:
24
Step-by-step explanation:
a linear function has the form: y = ax + b
According to the table: b = 5 and a = (43 − 5)/(2 − 0) = 38/2 = 19
Then our function is of the form: y = 19x + 5
Now ,we replace x by 1 in the function to get the missing value :
Missing value = 19(1) + 5 = 19 + 5 = 24.

[tex]\cfrac{\stackrel{small}{trapezoid}}{\stackrel{large}{trapezoid}}\qquad \stackrel{sides^2}{\cfrac{6^2}{9^2}}~~ = ~~\stackrel{areas}{\cfrac{A}{45}}\implies \cfrac{36}{81}=\cfrac{A}{45}\implies \cfrac{4}{9}=\cfrac{A}{45} \\\\\\ 180=9A\implies \cfrac{180}{9}=A\implies 20=A[/tex]
Whats the rate of change for (0,3) and (2,-5)
Answer:
[tex]\boxed{\sf{-4}}[/tex]Step-by-step explanation:
Solve a slope using a rate of change.
Slope:
[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
⇒ y2=(-5)
⇒ y1=3
⇒ x2=2
⇒ x1=0
Rewrite the problem down.
⇒ (-5)-3/2-0
Solve.
⇒ -8/2
Divide.
⇒ -8/2=-4
Therefore the slope is -4, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.

well, we know that π is 180°, so then what is 3π/5?

-5x+2<12 please someone help
Answer:
[tex]\boxed{\sf{x > -2}}[/tex]Step-by-step explanation:
Put the term x on one side of the equation.
-5x+2<12Subtract by 2 from both sides.
[tex]\Longrightarrow: \sf{-5x+2-2 < 12-2}[/tex]
Solve.
Subtract the numbers from left to right.
⇒ 12-2=10
⇒ -5x<10
Multiply by -1 from both sides.
⇒ (-5x)(-1)>10(-1)
Solve.
Multiply the numbers from left to right.
-5x*-1=5x
10*-1=-10
→ 5x>-10
Divide by 5 from both sides.
→ 5x/5>-10/5
Solve.
Divide the numbers from left to right.
-10/5=-2
[tex]\Longrightarrow: \boxed{\sf{x > -2}}[/tex]
Therefore, the correct answer is x>-2.I hope this helps you! Let me know if my answer is wrong or not.
Answer:
[tex]x > -2[/tex]
Step-by-step explanation:
Given the following question:
[tex]-5x+2 < 12[/tex]
To find this answer we subtract two on both sides then isolate the variable by dividing 5 on both sides.
[tex]-5x+2 < 12[/tex]
[tex]2-2=0[/tex]
[tex]12-2=0[/tex]
[tex]-5x < 10[/tex]
[tex]-5x\div-5=x[/tex]
[tex]10\div-5=-2[/tex]
[tex]x > -2[/tex]
Which means your answer is "x > -2."
Hope this helps.

Answer:
y=112
Step-by-step explanation:
If x=3.5 and y=14, you would divide 28 by 3.5 to get 8. Since x and y are directly proportional, you would times 14 by 8 to get y=112.
