Step-by-step explanation:
At which root does the graph of f(x) = (x – 5)2(x + 2)2 touch the x-axis?
-5
0-2
2
05
Answer:
Option B & D
Step-by-step explanation:
Function is;
f(x) = (x - 5)³(x + 2)²
We want to find the point in thich the graph of this function touches the x-axis.
Usually, the point at which the graph touches the x-axis means that y is 0 at that point.
Thus;
(x - 5)³(x + 2)² = 0
This means that;
x - 5 = 0 and x + 2 = 0
Thus,x = -5 and x = -2

Answer:
Here are the answers. Hope this helps you!
Step-by-step explanation:
11/12*9/22 = rational (as the solution is 33/88 which is in p/q form with q not equal to 0 and p and q as integers.)
√5 *8 = 8√5 = irrational
3 + √17 = irrational (sum of a rational and irrational number is always irrational)
√3*√12 = √36 = 6= rational number
π - 2π = -π = irrational (since π is irrational)
-3/8 + 3/5 = -15+24/40 = 9/40 = rational
√6/2 - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational (in this case difference is irrational and the product is clearly irrational as well).
y=x/3+2.

what are the values of AB and DE in parallelogram ABCD?
Answer:
AB equals 13 and DE equals 7.
Step-by-step explanation:
In a parallelogram, the opposite sides are equivalent, so AB will equal CD which equals 13. Based on this rule, you can infer that BC = AE + ED. Since BC equals 23 and AE equals 16, ED would be 7.
The solution is
The value of AB of the parallelogram is 13
The value of DE of the parallelogram is 7
What is a Parallelogram?
A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the parallelogram be ABCD
The value of side CD = 13
The value of side BC = 23
The value of side AE = 16
AD = AE + ED
And , Opposite sides are parallel in a parallelogram
Now , the value of side AB = CD
So , the value of side AB = 13
And , The value of side BC = AD
So , the value of AD = 23
AD = AE + ED
Substituting the values in the equation , we get
23 = 16 + DE
Subtracting 16 on both sides of the equation , we get
DE = 23 - 16
The value of side DE = 7
Hence , the value of side AB = 13 and value of side DE = 7

Dora buys some T-shirts for $8.75 each and pairs of shoes for $27.50 each. If she buys 4 T-shirts, how much money would she have to spend in all
8.75*4=35 so $35 for shirts
and depending on how many shoes she buys but lets just say one pair
35+27.50= 62.50 so it would be a total of $62.50
Step-by-step explanation:
4 shirts with each price $8.75 = 4 × $ 8.75= $ 351 pair of shoes with price = $ 27.50so total price = $ 35 + $ 27.50 = $ 62.50MARK ME AS BRAINLISTPLZ FOLLOW MESelect the three inequalities that have n = 3 in the solution set

D. 3n > 9.5
E. n-2<5
Answer:
Its just E
I'm sorry if I'm wrong
Answer: A, C, E
Solve for all the inequalitites.
n + 5 < 9
n < 9 - 5
n < 4
∴ n = 3 is a part of the solution set.
13n < 1
n < 1/13
∴ This definitely doesn't include n = 3.
3n + 1 > 7
3n > 6
n > 2
∴ n = 3 is part of the solution because n is larger than 2.
3n > 9.5
n > 9.5 ÷ 3
n > 3.16666666
∴ n = 3 is not part of the solution set.
n - 2 < 5
n < 5 + 2
n < 7
∴ n = 3 is a part of the solution set.

We have been given an isosceles triangle being two sides equal AB and AC
By the property of isosceles triangle
The sides which are equal will have same base angle
Hence, ∠ABC=∠ACB=
We know that sum of angles of triangle is
∠ABC+ ∠ACB+∠BAC= (1)
Since, ∠BAC is the bisector so, ∠BAD and ∠DAC are equal which is
Now, substituting the values in (1) we get:
Now, we will consider ΔABD to find x
,∠ADB=∠ABD=
Now, Apply the sum of angles of triangle is we get:
Answer:
x = 8[tex]\sqrt{7}[/tex]
y = 4[tex]\sqrt{21}[/tex]
Step-by-step explanation:
use the altitude rule to find the height of the triangle first
12/h = h/16
h² = 12x16
h = [tex]\sqrt{192}[/tex]
h = [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex]
now you can use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 12 to find 'y'; which comes out to be [tex]\sqrt{336}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{21}[/tex]
then use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 16 to find 'x'; which comes out to be [tex]\sqrt{448}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{7}[/tex]

What percent is 50% of 50% of x? Please help.
25% is 50% of 50.
Explaination is on the picture.
50% of 100 is 50.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Let x be a number such that
50% of x is 50
This forms an equation in one variable which can be solved by transposition.
[tex]50/100\times x = 50[/tex]
x/2=50
On multiplying 2 both sides,
[tex]X/2\times 2 =50\times 2[/tex]
X=100
Thus, 50% of 100 is 50.

Priya's family exchanged 250 dollars for 4,250 pesos. Priya bought a sweater for 510 pesos. How many dollars did the sweater cost? Pesos dollars 4,250 250 25 1 3 510
Answer:
$30
Step-by-step explanation:
since they exchanged them we can assume they are worth the same
250=4250
First find how many pesos is worth 1 dollar
4250/250= 17
Then divide the amount the sweater costs by how much 1 dollar would be
510/17= 30
The sweater would cost 30 dollars.
The population of a town has been growing, following the equation P=400t+3000, where t is years after 2010. The number of restaurants in the town has been growing according to the equation R=6t+35.
Complete an equation for the number of restaurants per capita (per person)
Restaurants per capita: ______
How many restaurants per capita does this model predict for the year 2016?_______
Please also explain it to me, only if you can! Thank you!
Step-by-step explanation:
t is time since 2010. so,
the population prediction for 2016 is :
p= 400 ( 2016-2010)+3000
p= 400 (6) + 3000=5400
the number of restaurant prediction for 2016 is.
R=6(2016-2010)+35
R=6 (6)+35=71
so, per capita (per person) there would be:
71 restaurant for 5400.
people that is :71/5400 or 0.0131 restaurant per person.
per restaurant there would be,5400/71 or 76.056 per restaurant.
population corresponding to time (t).
=( R/ P) = (6t + 35). / 400t + 3000, where t= 2016-2010= 6 years
= 71/5400
= 0.0131
Restaurant per capita
R/P = (6t+35) / (400t + 300)
t= 2016-2010 =16
R/P = (6.16+35) /(400.16+3000)
= 131 (6400+3000)
=85/9400
=0.009042

In the figure below, mROP = 125°.
Find the measure of each arc. For each arc, write two or more complete sentences explaining which theorem or postulate you used to find your answer. Include your equations and calculations in your final answer.
Step-by-step explanation:
first we notice that the line RS makes a diagonal in the circle.Since we are given ROP we can find SOP by:
180⁰-125⁰=55⁰
since they are in each others opposite point they are equal so that means that if we try the equation we did before: SOQ =ROP and QOR=SOP
Step-by-step explanation:
step 1. mPOS = 180 - 125 = 55°. (supplementary angles)
step 2. mQOS = 125° (vertical angles)
step 3. mQOR = 180 - 125 = 55° (supplementary angles).
Use the graph of the polynomial function to find the factored form of the
related polynomial. Assume it has no constant factor.
A. (x + 1)(x-7)
B. (x + 1)(x + 7)
C. (x - 1)(x-7)
D. (x - 1)(x + 7)
The factored form of the related polynomial function is (x - 1)(x - 7).
What is polynomial function ?Polynomial function is a function that involves non-negative integer powers or positive integer exponents of a variable in an equation like the quadratic equation, cubic equation.
We have,
In the graph given in question, we can see that x - intercepts the axis twice.
And graphs behave differently at various x - intercepts. Sometimes the graph will cross over the x-axis at an intercept and other times the graph will touch the x-axis and bounce off.
Now, in graph;
The intercept at x = 1 ,
i.e. the solution of the x - 1 = 0 and passes through the axis.
Now,
The x - intercept at x = 7, is the solution of x - 7 = 0 and again passes through the axis.
So, from the above statements we can say that the factored form of the related polynomial is (x - 1)(x - 7)
Thus, we can say that the factored form of the related polynomial function is (x - 1)(x - 7).

The set of values (63, 64, 65, 66} represents solutions of which inequality?
Answer: 63 < N ≤ 66
Step-by-step explanation:
We have the set:
(66, 64, 65, 66]
First.
When we have an end with the signs "(" or ")" means that the element near the sign does not belong to the set, this would be an "open" end. Usually used for the symbols > and <
While the sign "[" or "]" (in some cases the symbols { and } are used instead)
means that the value next to it are included in the set. Usually used for the symbols ≤ and ≥.
Then in the set: (63, 64, 65, 66} the value 63 does not actually belong, and value 66 does belong.
Then this set is written as:
63 < N ≤ 66
Such that N is an integer number.
