1 answer:
r-ruslan [8.4K]3 years ago

Answer:

See explanations below

Step-by-step explanation:

Given the polynomial function

P(x) = X^2+3x-10

To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0

For x-2

x - 2 = 0

x =2

P(2) = 2²+3(2)-10

P(2) = 4+6 -10

P(2) = 10-10

P(2) = 0

Since the remainder is zero, hence x-2 is a factor of the polynomial

Similarly for x+5;

x+5 = 0

x = -5

P(-5) = (-5)²+3(-5)-10

P(-5) = 25-15-10

P(-5) = 10-10

P(-5) = 0

This also shows that x+5 is a factor

zhannawk [14.2K]

Answer:

Step-by-step explanation:

hello :

(0.04)^3/2=√(0.04)^3 =√(2²/10^2)^3 = √((2/10)^2)^3

(0.04)^3/2=√((2/10)^3)^2=8/1000 = 0.008

Circle A is shown. Secant W Y intersects tangent Z Y at point Y outside of the circle. Secant W Y intersects circle A at point X
Gekata [30.6K]

By applying the theorem of intersecting secants, the measure of angle XYZ is equal to: A. 35°.

<h3>How to determine angle <XYZ?</h3>

By critically observing the geometric shapes shown in the image attached below, we can deduce that they obey the theorem of intersecting secants.

<h3>What is the theorem of intersecting secants?</h3>

The theorem of intersecting secants states that when two (2) lines intersect outside a circle, the measure of the angle formed by these lines is equal to one-half (½) of the difference of the two (2) arcs it intercepts.

By applying the theorem of intersecting secants, angle XYZ will be given by this formula:

<XYZ = ½ × (m<WZ - m<XZ)

Substituting the given parameters into the formula, we have;

<XYZ = ½ × (175 - 105)

<XYZ = ½ × 70

<XYZ = 35°.

By applying the theorem of intersecting secants, we can infer and logically deduce that the measure of angle XYZ is equal to 35°.

Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.​
Lera25 [3.4K]

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C = 2\pi r

Plug 35 in for r (radius) and solve.

C = (35) 2\pi\\\\C = 70\pi\\\\C = 219.9

So, approximately 219.9 in^2 is the answer.
