Answer:

Step-by-step explanation:

We know a triangle adds up to 180 so:

75+36+ ? = 180

111+ ? =180

? = 69

To find out x, we know that a straight line adds up to 180 so again:

x +69 = 180

x = 111

Answer:

let the untitled angle be y.

y+75°+36°=180°[by angle sum property]

y+111°=180°

y=180°-111°

y=69°

x+69°=180°[by linear pair]

x=180°-69

x=111°

Answer:

37/6

Step-by-step explanation:

Simplify the following:

(12 + 1/3)/2

Put 12 + 1/3 over the common denominator 3. 12 + 1/3 = (3×12)/3 + 1/3:

((3×12)/3 + 1/3)/2

3×12 = 36:

(36/3 + 1/3)/2

36/3 + 1/3 = (36 + 1)/3:

((36 + 1)/3)/2

36 + 1 = 37:

(37/3)/2

37/3×1/2 = 37/(3×2):

37/(3×2)

3×2 = 6:

Answer: 37/6

Suppose a set of data about the spread (in hundreds of acres) of a food-borne bacteria (after t weeks) in lettuce has the follow
Alexxandr [17]

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

Can yall help me out
Ainat [17]

Answer:

Option D, Yes, Devon should have evaluated f(3)

Step-by-step explanation:

f(x) = x^3 + x^2 − 10x + 8

<u>Step 1:  Evaluate using F(3) NOT f(-3)</u>

f(3) = 3^3 + 3^2 - 10(3) + 8

f(3) = 27 + 9 - 30 + 8

f(3) = 14

Since the factor is (x - 3) the x value is x - 3 + 3 = 0 + 3 -> x = 3 not x = -3

Answer:  Option D, Yes, Devon should have evaluated f(3)

Let g(x)=9x−10 and evaluate g(x+h)−g(x)/h
castortr0y [4]

Answer:

\frac{g(x+h)-g(x)}{h}=9

Step-by-step explanation:

we have

g(x)=9x-10

To find out g(x+h) substitute the variable x by the variable (x+h) in the function g(x)

so

g(x+h)=9(x+h)-10

g(x+h)=9x+9h-10

Evaluate

\frac{g(x+h)-g(x)}{h}

we have

g(x+h)=9x+9h-10

g(x)=9x-10

substitute in the expression

\frac{9x+9h-10-(9x-10)}{h}

\frac{9x+9h-10-9x+10)}{h}

\frac{9h}{h}

9

therefore

\frac{g(x+h)-g(x)}{h}=9
