What are the zeros of the function f(x) = x2 + 7x – 18? Enter your answers in the boxes with your greatest answer first. The zeros of f(x) ar AN A/
Answer:
The answer is 2 and (-9)
Step-by-step explanation:
x² + 7x – 18 = 0
x² + 9x – 2x – 18 = 0
x(x + 9) – 2(x + 9) = 0
(x – 2) (x + 9) = 0
x = (2, -9)
Thus, The zeroes of the polynomial is 2 and (-9).

List the angles from smallest to largest.

, angle
✔ A
.
Answer:
m(C)<m(B)<m(A).
Step-by-step explanation:
1) according to the condition the shortest side is AB, the longest side is BC, the middle is AC. Then
2) the smallest angle is BCA (or C), the middle angle is ABC (or B), the largest angle is BAC (or A).
The list of the angles from smallest to largest are C, B and A.
Given that a triangle has side measurements represented in terms of the variable m, where m > 6.
AB = m - 2
BC = m + 4
AC = m
We need to list the angles from smallest to largest.
Since none of the sides are equal, therefore it is a scalene triangle.
Let us consider m = 6.
Then,
AB = m - 2
AB = 6 - 2
AB = 4
BC = m + 4
BC = 6+4
BC = 10
AC = m
AC = 6
It means that the longest side is BC, the medium side is AC and the shortest side is AB.
We know that the longest side of a triangle corresponds to the largest angle and vise versa.
Therefore,
The smallest angle is angle C.
The medium angle is angle B.
The largest angle is angle A

Determine the equation of a circle with its centre at the origin in the Cartesian plane and with a radius of 2√3 units
Answer:
x^2 + y^2 = 12
Step-by-step explanation:
For a circle with the center at the origin [(h,k) is (0,0)]
use the formula:
x^2 + y^2 = r^2
In this case r is 2sqroot3.
(2sqroot3)^2 is 12.
2•2•sqrt3•sqrt3
= 4•3
= 12
So we get,
x^2 + y^2 = 12

Without using a calculator, order the following expressions from least to greatest.
11/3, square root 20, square root 17
Answer:
[tex]\displaystyle \large{\frac{11}{3} < \sqrt{17} < \sqrt{20}}[/tex]
Step-by-step explanation:
( 1 ) 11/3
[tex]\displaystyle \large{\frac{11}{3}}[/tex] can be converted to mixed fractions to [tex]\displaystyle \large{3\frac{2}{3}}[/tex]
Therefore, 11/3 is at least around 3, almost 4. It could be more than 3.5 by approximation but not exactly 4.
( 2 ) √20
[tex]\displaystyle \large{\sqrt{20}=\sqrt{5\cdot 4}}\\\displaystyle \large{\sqrt{20}=\sqrt{5\cdot 2\cdot 2}}\\\displaystyle \large{\sqrt{20}=2\sqrt{5}}[/tex]
We know that [tex]\displaystyle \large{\sqrt{4}=2}[/tex] so [tex]\displaystyle \large{\sqrt{5} > \sqrt{4}}[/tex] which means approximately, [tex]\displaystyle \large{\sqrt{20}}[/tex] can be either at least 4.3 up to 4.4
( 3 ) √17
We know that [tex]\displaystyle \large{\sqrt{16} = 4}[/tex] so [tex]\displaystyle \large{\sqrt{17}}[/tex] can be at least 4.1 up to 4.2, but it’s obvious that the square root of 17 is less than square root of 20 since [tex]\displaystyle \large{\sqrt{a} > \sqrt{b}}[/tex] for a > b
Hence, from least to greatest:
[tex]\displaystyle \large{\frac{11}{3} < \sqrt{17} < \sqrt{20}}[/tex]
Find the area of each regular polygon below. Round values to the nearest 0.01. Show work for all steps clearly.
The area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively.
Data;
apothem = 15Area of a HexagonThe area of a hexagon with apothem 15 can be calculated by first finding the length of the side of the hexagon.
Length of hexagon can be found using trigonometric ratio;
[tex]a = x\sqrt{3}[/tex]
Making x the subject of formula
[tex]x = \frac{a}{\sqrt{3} }\\x = \frac{15}{\sqrt{3} }\\x = 8.660[/tex]
And then the length of the side is 2x
[tex]s = 2 * 8660 = 17.32[/tex]
The perimeter of the hexagon is;
[tex]p = 6s \\p = 6 * 17.32=103.92[/tex]
And the area is given as
[tex]A = \frac{1}{2} * perimeter * apothem\\A = \frac{1}{2} * 103.92 * 15\\A = 779.4unit^2[/tex]
The area of the hexagon is 779.4 squared unit.
Area of the pentagonThe area of the pentagon can be found using several methods, but we can simply find the angle between the sides if we divide the pentagon into 10 pieces and then substitute the formula.
Total area of a pentagon is 360 degree.
[tex]\theta = \frac{360}{10} = 36^0\\[/tex]
The area of a pentagon is given as
[tex]A = \frac{5s^2}{4 tan \theta} \\A = \frac{5 * 7^2}{4* tan36} \\A = 84.303cm^2[/tex]
The area of the pentagon is 84.303cm^2
From the calculations above, the area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively

Answer:
X = 9Step-by-step explanation:
In this question we have provided an equation that is 10 + X/3 = 13 . And we're asked to find the value of X .
Solution : -
[tex] \longmapsto \qquad \: 10 + \dfrac{X}{3} = 13[/tex]
Step 1 : Multiplying with 3 on both sides :
[tex]\longmapsto \qquad \:(10 + \dfrac{X}{3} ) \times 3=13\times3[/tex]
Now by using distributive property multiplying 3 with 10 as well as X/3 :
[tex] \longmapsto \qquad \: (10 \times 3) + ( \dfrac{X}{ \cancel{3}} \times \cancel{3}) = 13 \times 3[/tex]
On calculating further , We get :
[tex] \longmapsto \qquad \: 30 + X = 39[/tex]
Step 2 : Subtracting with 30 on both sides :
[tex] \longmapsto \qquad \: \cancel{30} + X - \cancel{30} = 39 - 30[/tex]
On calculating further , We get :
[tex] \longmapsto \qquad \: \purple {\underline{{\boxed{\frak{X= 9}}}}}[/tex]

A: y=2x +2
B: y=2x +3
C: y=3x +2
D: y=3x +3
Answer:
B: y = 2x + 3
Step-by-step explanation:
The 2x is the slope, and the 3 is the y-intercept
The y-intercept is kinda like how far the slope is from zero, but it can only be applied to the y-axis.
The slope is... well... the slope-- like how steep it is. If a slope is 2/1, like in the graph, it will go higher 2 units every 1 unit across. Or, if the slope is 1/4: The slope will go 1 unit higher every 4 units
A mobile set after allowing a discount of 10% on its marked price, was sold at a gain of 20%,Had it been sold after allowing 20% discount,there would have been a profit Rs.350. Find the cost price and marked price of the mobile set.
Answer:
Let x be the cost price.
Let y be the marked price
Gain = 20%
Then , sale price = 120/100 * x = 1.2x
Now , sale price is after 10% discount from marked price.
Hence , marked price, y = 1.2x/90 * 100 =
y * 0.9 = x * 1.2
Now, with 20% discount, sale price = y * 80/100 = 0.8y
Now, profit = 0.8y — x
Now, 0.8y — x = 350
0.8 * x * 1.2/0.9 — x = 350
1.0667x — x = 350
Hence, x = 350/0.0667= Rs.5250
Hence marked price = (5250 + 350) * 100/80 = Rs.7000

blank 1 = 20blank 2 = 5.7blank 3 = 57============================================================
Explanation:
The perimeter p refers to the perimeter of the base polygon. We have five equal sides of 4 inches each, which therefore leads to a perimeter of p = 5s = 5*4 = 20
The perimeter is 20 inches.
This is the answer for blank 1.
This is the amount of fencing needed to enclose the pentagonal base.
-------------------------------
The l, aka lowercase L, is the slant height. It refers to the distance from the midpoint of any side of the base to the peak of the pyramid.
The diagram shows the slant height is 5.7 inches which is the answer for blank 2.
-------------------------------
LA = lateral surface area
The lateral area is the area of everything except for the base polygon.
Each triangle has a base of 4 inches and height 5.7 inches.
Each triangle has an area of base*height/2 = 4*5.7/2 = 11.4 square inches.
Five such identical copies yields a total LA of 5*11.4 = 57 square inches which is the answer for blank 3.
For each blank, you'll only enter the number itself of course.
The 2.8 in the diagram is never used. It's only useful if you needed to find the volume.

The correct option is A.
What is Congruency?Congruency is a concept in geometry that refers to the equality of shape and size between two or more geometric figures. When two figures are congruent, it means that they have exactly the same shape and size, and their corresponding sides and angles are equal.
In ΔABC and ΔDCB
