Answer: f(x)=3x2+30x+65

Step-by-step explanation:

F(x)=3(x+5)2-10

Using bodmas

B= bracket

O=of

D= division

M= multiplication

A= Addition

S= subtraction

So we go with the bracket

(X+5)2

=(x+5)(x+5)

Open the bracket

=x2+5x+5x+25

=x2+10x+15

Substitute for (x+5)2

F(x)=3(x2+10x+25)-10

Open the bracket

F(x)= 3x2+30x+75-10

F(x)= 3x2+30x+65

The following graph describes function 1, and the equation below it describes function 2. Determine which function has a greater
LenaWriter [7]

Answer:

Function 1 has the larger maximum at (4, 1)

Explanation:

After observation, graph of function 1 has vertex at Maximum (4, 1)

In order to find vertex of function 2, complete square the equation.

f(x) = -x² + 2x - 3

f(x) = -(x² - 2x) - 3

f(x) = -(x - 1)² - 3 + (-1)²

f(x) = -(x - 1)² - 2

Vertex form: y = a(x - h)² + k where (h, k) is the vertex

So, here for function 2 vertex: Maximum (1, -2)

<h3>Conclusion:</h3>

Function 1 = Maximum (4, 1), Function 2 = Maximum (1, -2)

Function 1 has greater maximum value of (4, 1) as "1 is greater than -2"

A triangle has two sides measuring 10 inches and 16 inches. The angle opposite the 16-inch side measures 68.9°. Solve the triang
Nezavi [6.7K]

Answer:

measure of two unknown angles are 35.7° and 75.4°

measure of one unknown side is 16.6 inches

Step-by-step explanation:

i used law of sines to find the angle opposite 10 inch side

sin 68.9/16 = sinФ/10

Ф = 35.7°

then is added 35.7 and 68.9 and subtracted the sum from 180° to get the measure of the third angle, 75.4°

i used law of sines again to find the measure of the third side

sin 68.9/16 = sin 75.4/x

x = 16.59

5z-12z-10=18+7z<br><br> Im not sure how to do this
OLga [1]

Answer:

The answer is z = -2

Step-by-step explanation:

You combine like terms.

Then subtract 7z from both sides.

Add 10 to both sides.

Then divide both sides by -14. (28/-14)

Which then equals to -2
