For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the x-axis at each x -intercept.
f(x) = 3(x + 7)(x + 3)^2?
A? B? C? D?
Answer:
B
Step-by-step explanation:
You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.
[tex]x+7=0\\x+3=0[/tex]
Solve them both and you get:
[tex]x=-7\\x=-3[/tex]
Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.
Therefore the answer is B since that agrees with everything we said.

Opposite Angles are supplementary in cyclic quadratlerials.
in the diagram,the measure of angle ACB is 25 degrees. what is the measure of angle AOB?
Answer:
m<AOB = 50°
Step-by-step explanation:
<ACB = 25° is an inscribed angle of the circle.
<AOB is a central angle of the circle.
Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:
m<ACB = ½(m<AOB)
Substitute
25° = ½(m<AOB)
Multiply both sides by 2
2*25 = m<AOB
m<AOB = 50°

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257

Answer:
a. C(x(h)) = 600h + 500
b. C(8) = 5,300
c. See below.
Step-by-step explanation:
a. C(x(h)) = C(30h) = 20(30h) + 500 = 600h + 500
b. C(8) = 600(8) + 500 = 5,300
c. 5,300 is the cost of making the number of shovels that can be made in 8 hours.
A triangle has angles measuring 35° and 90°. What is the measure of the third angle?
Answer:
55 degrees
Step-by-step explanation:
All the angles of a triangle should add up to 180 degrees.
So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.
35+ 90 + x = 180
125 + x = 180
x = 55

Work out the percentage change when a price of £10 is increased to £14
Answer:
hmmm well.
Step-by-step explanation:
they added £4
Answer:
40%
Step-by-step explanation:
The formula for percentage change is given by:
[tex]\boxed{\text{Percentage change}=\frac{\text{New}-\text{Original}}{\text{Original}}\times100\% }[/tex]
In this case, the original price is £10 while the new price is £14.
Substitute the values into the formula:
Percentage change
[tex]=\frac{14-10}{10} \times 100\%[/tex]
= 40%

X=49°
Step-by-step explanation:
we have an isosceles triangle
thus our equation is
x+x+82=180°
=>2x+82°=180°
cancel 82 from both sides
=>2x=98
divide both sides by 2
therefore
X=49

-5 = 1/7a
Answer:
-35
Step-by-step explanation:
[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a

Can anyone please help me to do this with steps
Answer:
x = 58°
Step-by-step explanation:
ABCD is a cyclic quadrilateral and opposite angles are supplementary , so
∠ DAB = 180° - 121° = 59°
The angle between a tangent and a chord is equal to the angle in the alternate segment, then
∠ ABD = 63° , thus
x = 180° - (59 + 63)° = 180° - 122° = 58°
In if GS ⊥ XJ and XJ⊥EA what is true about GS and EA
Answer:
([tex]GS[/tex]) || ([tex]EA[/tex])
Step-by-step explanation:
When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines ([tex]GS[/tex]) and ([tex]EA[/tex]) are parallel.
The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

6. How far is it from the point (-5, 7) to the point (6,-2)? Round your answer to the nearest tenth.
Answer:
14.2 units
Step-by-step explanation:
Here x increases by 11 from -5 to +6. This is the length of the horizontal leg of a right triangle. Then y decreases by 9 from 7 to -2. This is the length of the vertical leg. The hypotenuse of this triangle may be found using the Pythagorean Theorem:
11^2 + 9^2 = (hypotenuse)^2, or
hypotenuse = √(121 + 81) = √202 ≈ 14.2 units
Answer:
≈ 14.2
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, - 2)
d = [tex]\sqrt{(6+5)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{11^2+(-9)^2}[/tex]
= [tex]\sqrt{121+81}[/tex]
= [tex]\sqrt{202}[/tex]
≈ 14.2 ( to the nearest tenth )
