Yes, exponential or log I think! It is a function — use vertical line test

30) Find the 29th term of the following sequence. <br><br> 27, 24, 21, 18, . . .
zheka24 [161]
Using the arithmetic formula a1 + (n-1) d, a1 being the first term, n being the number you’re looking for and d being the common difference, you will get the answer of -57.

Here’s the work:

27 + (29 - 1) -3
27 + (28) -3
-57

Can someone help me asap <br>I attempted to do it so just ignore that part ​
Sladkaya [172]

Answer:

a = 180° -73°

b = 73°

c = 180° -73°

Step-by-step explanation:

73° and b are vertical angles, so are congruent (equal).

a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...

a + 73° = 180°

but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.

HELP PLEASE! Write a quadratic function that passes through the point (-1,9), has an axis of symmetry of x=-3 and a minimum valu
xxTIMURxx [149]

Answer:

y = \frac{1}{2}x^{2} - 3x + 11.5

Step-by-step explanation:

Vertex form of a quadratic equation;

y = a( x - h )^{2} + k

Vertex of the parabolas (h, k)

The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;

y = a ( x + 3 ) ^{2} + 7

Now substitute in the given point; ( -1, 9) and solve for a;

9 = a( (-1 ) + 3)^2 + 7\\9 = a (2)^{2} + 7\\9 = 4a + 7\\-7           -7\\2 = 4a\\\frac{1}{2} = a\\

Hence the equation in vertex form is;

y = \frac{1}{2}(x - 3)^{2} + 7

In standard form it is;

y = \frac{1}{2}x^{2} - 3x + 11.5
