3.3^(2x+1)-103^x+1=0 need solution of this question
Answer:
Concepts of mathematics Answer: x= -1.53Adélie penguins in the Danger Islands represent about 55% of the total Adélie penguin population in the Antarctic Peninsula. They calculated a total of 1,503,054 penguins on the islands.
What is the total estimated Adélie penguin population in Antarctica?
Answer:
Adélie penguins= 826,680
Step-by-step explanation:
Giving the following information:
Total penguin population= 1,503,054
Adélie penguins= 55%
To calculate the number of Adélie penguins, we need to use the following formula:
Adélie penguins= total penguin polulation*proportion of Adélie penguins
Adélie penguins= 1,503,054*0.55
Adélie penguins= 826,680

What is -2 2/3 divide by -1/2
Answer:
16/3
Step-by-step explanation:
Answer:
5 1/3
Step-by-step explanation:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−8/3 ÷ −1/2
Applying the fractions formula for division,
=−8×2/3×−1
=−16/−3
Simplifying -16/-3, the answer is
=5 1/3

Determine if the two triangles are congruent. If they are, state how you know.
A. SAS
B. not enough information
C. SSS
D. AAS
Answer:
A. SAS
Step-by-step explanation:
Since the marked angle is between the marked sides, and the corresponding sides are marked as congruent, the two triangles are congruent by SAS (side angle side).

Solve for x. I’ll give BRAINLIEST!!
Answer:
x = -7
Step-by-step explanation:
Firstly, under the rule of opposite vertical angles, you know that any angles opposite of each other in a cross section have the same degree measure.
Therefore the last remaining angle in the triangle will be 85 degrees, since it is vertically opposite of the 85 degree angle.
Next, you know that all three angles of a triangle MUST equal 180 degrees to be considered a complete triangle.
Therefore, use the equation below to solve for x:
180 = 54 + 85 + (48 + x)
x = 180 - 54 - 85 -48 = -7

Write an equation for the line that passes through the point -3,2 and is parallel to line 4X + 2Y= -10
9514 1404 393
Answer:
2x +y = -4
Step-by-step explanation:
The equation of the given line can be simplified by dividing all of the numbers by 2:
2x +y = -5
The parallel line can have the same coefficients of x and y, but will have a different constant. The constant will be appropriate to the given point, so will be ...
2x +y = constant
2(-3) +(2) = constant = -6 +2 = -4
The parallel line is ...
2x +y = -4

Answer: b=-12
Step-by-step explanation:
120/-10 = -12
-10b/-10 = b
b=-12
Answer:
b= -12
Step-by-step explanation:
you would divide -10 on both sides of the equation and get -12= b or b= -12.

Which equation represents a line which is perpendicular to the line 4x
y = -2?
Answer:
y=4x +7 (top-left)
Step-by-step explanation:
They have the same exact slope meaning they can not cross.
The only time they would cross is if they had the same y-intercept. Which they don't

Select the correct graph of the function y = –1/8(x – 1)2 – 4 below.
Question 8 options:
A)
image
B)
image
C)
image
D)
image
Step-by-step explanation:
The given function is :
[tex]y=\dfrac{-1}{8}(x-1)^2-4[/tex] ...(1)
It is an equation of parabola. The vertex form for equation of parabola is given by :
[tex]y=a(x-h)^2+k[/tex] ...(2)
Here,
Vertex = (h,k), axis = h and rate = a
From equation (1) and (2) :
a = -1/8, h = 1 and k = -4
The atached graph shows the graph for the given equation.
If cos a= 0.93,Sin 0 =0.26, and tan ß = 0.84, find a + B + 0.
Answer:
76.665
Step-by-step explanation:
Given that,
cos α = 0.93, Sin θ =0.26 and tanβ = 0.84
We need to find the value of α, β and θ
[tex]\alpha =\cos^{-1}(0.93)\\\\=21.565\\\\\beta =\tan^{-1}(0.84)\\\\=40.030\\\\\theta=\sin^{-1}(0.26)\\\\=15.07[/tex]
So,
[tex]\alpha +\beta +\theta=21.565+40.03+15.07\\\\=76.665[/tex]
Hence, the final answer is 76.665.

find the coordinates of the centroid of the triangle with the given vertices. D(-4, -2), E(1, 0), F(9, 5)
Answer:
[tex] (x, y) = (2, 1) [/tex]
Step-by-step explanation:
Given vertices of a triangle:
[tex] (x_1, y_1) = (-4, -2) [/tex]
[tex] (x_2, y_2) = (1, 0) [/tex]
[tex] (x_3, y_3) = (9, 5) [/tex]
Using the centroid formula:
[tex] (x, y) = (\frac{x_1 + x_2 + x_3}{3}, \frac{y_1 + y_2 + y_3}{3}) [/tex]
Plug in the values into the formula
[tex] (x, y) = (\frac{-4 + 1 + 9}{3}, \frac{-2 + 0 + 5}{3}) [/tex]
[tex] (x, y) = (\frac{6}{3}, \frac{3}{3}) [/tex]
[tex] (x, y) = (2, 1) [/tex]
