Exponential growth
Step-by-step explanation:
Since this is a logarithmic equation, it will have a limit of -5. from negative 5, it will increase in both y and x values. In the equation, it says 2^x, so the greater the x value, the greater the y value. Therefore, it is increasing.

Find the solutions of the quadratic equation -9c² +2 +3 = 0.
Answers
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Here, a = -9, b = 2 and c =3
Put the values,
[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]
So, the solution are -0.47 and 0.69.
Which graph represents an exponential function?
Answers
Answer:
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

38 °
Step-by-step explanation:

so, we subtract 180 - 106 = 74
then we subtract 74-36 = 38°
?= 38°
find the value of x in the figure
Answers
Answer:
Option (4)
Step-by-step explanation:
By applying triangle sum theorem in ΔABC,
m∠A + m∠B + m∠C = 180°
80° + 40° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]
m∠DCE = m∠ACB = 60°
Now by applying triangle sum theorem in ΔCDE,
m∠DCE + m∠CED + m∠CED = 180°
60° + 70° + x° = 180°
x = 180 - 130
x = 50°
Therefore, Option (4) will be the answer.

a math student is standing 40 feet from the base of a water tower. the angle of elevation from her horizontal line of sight is 72 degrees. If her "eye height" is 5 feet, how tall is the water tower? Round to the nearest foot.
Answers
9514 1404 393
Answer:
128 ft
Step-by-step explanation:
The height of the tower above eye-height is related to the angle by ...
Tan = Opposite/Adjacent
tan(72°) = (tower height above eye height)/(40 ft)
tower height above eye height = (40 ft)×tan(72°) = 123 ft
Since eye height is 5 ft, the total height of the tower from the ground is ...
tower height = eye height + height above eye height
tower height = 5 ft + 123 ft
tower height = 128 ft
Figure ABCD is transformed to figure A′B′C′D′:

b. Angle A prime B prime C prime.
c. Angle B prime C prime D prime.
d. Angle C prime D prime A prime.
Answers
Answer:
D. <C'D'A'
Step-by-step explanation:
Given that figure ABCD is transformed to figure A′B′C′D′, therefore the angles of ABCD would be congruent to the corresponding angles of A′B′C′D′.
<CDA corresponds to <C'D'A'. Therefore:
<CDA = <C'D'A'

What is 3/11 of 22/39?
Answers
Answer:
0.1538
Step-by-step explanation:
first convert 3/11 into a percentage
3÷11=0.272727272727273
0.272727272727273 × 100
27.272727272727/100
27.272727272727%
≈27.27%
27.27% of 22/39
change 22/39 into a decimal
22÷39=0.5641025641》0.564
27.27% of 0.564
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 27.27% * 0.564
Converting percent to decimal:
p = 27.27%/100 = 0.2727
Y = 0.2727 * 0.564
Y = 0.1538

D. The other solution to function h is 4 + 7i.
The answer isn't A. Function h has no other solutions.
I hope this helps.
Answers
Answer:
B. The other solution to function [tex]h[/tex] is [tex]-4-i\,7[/tex].
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form [tex]a\cdot x^{2}+b\cdot x + c[/tex] has solutions of the form:
[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], where both are complex if and only if [tex]\sqrt{b^{2}-4\cdot a \cdot c}< 0[/tex].
Hence, if one solution of the quadratic function is [tex]-4+i\,7[/tex], then the other solution is [tex]-4-i\,7[/tex]. The correct answer is B.
