The smallest positive integer that the intermediate value theorem guarantees a zero exists between 0 and a is 3.

What is the intermediate value theorem?

Intermediate value theorem is theorem about all possible y-value in between two known y-value.

x-intercepts

-x^2 + x + 2 = 0

x^2 - x - 2 = 0

(x + 1)(x - 2) = 0

x = -1, x = 2

y intercepts

f(0) = -x^2 + x + 2

f(0) = -0^2 + 0 + 2

f(0) = 2

(Graph attached)

From the graph we know the smallest positive integer value that the intermediate value theorem guarantees a zero exists between 0 and a is 3

For proof, the zero exists when x = 2 and f(3) = -4 < 0 and f(0) = 2 > 0.

Your question is not complete, but most probably your full questions was

Given the polynomial f(x)=− x 2 +x+2 , what is the smallest positive integer a such that the Intermediate Value Theorem guarantees a zero exists between 0 and a ?

The transformation f(x)—>f(1/3x) due to the graph of f(x), will be dilation horizontally and vertically.

What is Transformation of Function?

Transformation of functions refers to the graph's curve moving to the left, right, up, or down, expanding, contracting, or reflecting. Just dilation, out of these three transformations, alters the size of the original shape; the other two only adjust the position.

A translation happens when each point on a graph (which represents a function) travels in the same direction and by the same amount. There are two kinds of function translations.

Stretching or compressing is a dilation. The x-values on a graph are all scaled up by the same amount when a dilation that is parallel to the x-axis occurs. The y-values are all increased by the same scale factor if it is dilated parallel to the y-axis.

f(x) to become f(1/3x), Then it will go dilation "vertically and horizontally".

Referring to the graph mentioned below we can conclude the same.

The value of sin θ of the given right angle triangle using trigonometric ratios is; A: 5/13

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). They are based on the angles formed from the ratio of sides of a right angle triangle. Thus;

sin θ = opposite/hypotenuse

cos θ = adjacent/hypotenuse

tan θ = opposite/adjacent

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

From the given image, we see that;

Hypotenuse = 13

Adjacent = 12

Opposite = 5

Thus;

tan θ = 5/12

θ = tan⁻¹(5/12)

sin θ = 5/13

By applying the exterior angle property, the measure of the exterior angle to ∠G in triangle EFG is 120.7°

In Mathematics, the exterior angle property can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle.

To determine the value of ∠G in triangle EFG (ΔEFG), we would have to apply exterior angle property.

Then, the exterior angle property can be used to model triangle EFG (ΔEFG)  is given by:

∠G = m∠E +m∠F

The set of probabilities for the number of eaglets is the

probabilities for how many eaglets will survive.

The table that shows the probability distribution is the option C;

X      0         1         2

p(x)   0.35   0.60   0.05

  P(O) = 0.5 is the likelihood that the elder eaglet will live.

  Therefore;

   P(O') = 1 - 0.5 = 0.5 is the probability that the older eaglet won't survive.

  The likelihood that the younger eaglet will survive if the older eaglet              does not P(Y|O) = 10%

Therefore;

The likelihood that the elder eaglet will live while the younger eaglet does not survive is P(Y'|O) = 1 - 10% = 90%.

When the older eaglet does not survive, the younger eaglet has a 30% survival chance (P(Y|O')).

Therefore;

The likelihood that the younger eaglet will not survive, compared to the elder eaglet, is P(Y'|O') = 1 - 30% = 70%

The collection of potential probabilities for the number of eaglets that survive is expressed as the probability distribution, or P(X)

The range of potential results includes:

Never survives:

The likelihood that no eaglets survive is equal to P(O') × P(Y'|O') = 0.5 × 0.7 = 0.35.

The only survivor is:

The likelihood that only one eaglet survives is determined by P(O) = P(Y'|O) × P(O') = P(Y|O'), which results in P = 0.5 × 0.9 + 0.5 × 0.3 = 0.6 Both survive:

The odds of both eaglets surviving are P(O) ×P(Y|O) = 0.5 × 0.1 = 0.05.

Some laws of exponents are:

We need to check if 8.1^4 x 8.1^8 be equal to 8.1^12 and if 8.1^12 be equal to 8.1^6.

We will use laws of exponents to solve the given expression:

8.1^4 x 8.1^8 = 8.1^(4 + 8) = 8.1^12

So, 8.1^4 x 8.1^8 = 8.1^12

Also,

8.1^12 = 8.1^(2 * 6) = (8.1^2)^6

So, 8.1^12 ≠ 8.1^6.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another. In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. The "not equal symbol ()" is typically used to indicate that two values are not equal. The expression 5x 4 > 2x + 3 resembles an equation, but the equals sign has been replaced by an arrowhead. It is an illustration of inequality. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3.

Tommasa's grandmothers rule is to subtract 32 from the value in °F and multiply the result by 0.5

i.e. [tex]^{0}C = 0.5(T^{0} F-32)[/tex]   - 2

Given temperature is T = 50°F

Put the value of T in equation 2

If Casey's monthly phone bill was $38.44, how many minutes did she use? 

The total charges of the flat rate per month = $3.99

The total additional charge per minute = $0.05

Total monthly bill = $38.44

Total additional charge = Total monthly bill - Total charge of flat rate
