Answer:

(-1,-4) is the vertex

x = -1 is the equation of symmetry;

Step-by-step explanation:

See attached image.

Answer:

(- 1, - 4 ) and x = - 1

Step-by-step explanation:

given a parabola in standard form

y = ax² + bx + c ( ax≠ 0 )

then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x - 3 ← is in standard form

with a = 1, b = 2 , then

x = - [tex]\frac{2}{2}[/tex] = - 1

substitute x = - 1 into the equation for corresponding y- coordinate

y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4

vertex = (- 1, - 4 )

this is an upward opening parabola ( a > 0 )

the axis of symmetry is a vertical line passing through the vertex with equation

x = c ( c is the value of the x- coordinate of the vertex ), then equation is

x = - 1

The area of the unshaded region of the circle will be 120π units squared.

The area of a sector of a circle of radius r having an angle a° is given by:

Area of sector = (π*[tex]r^{2}[/tex])*(a°/360°) units squared.

Given ∡KLM = 60°. The radius of the circle is 12 units.

⇒The area of shaded sector KLM =  (π*[tex]12^{2}[/tex])*(60°/360°) = π·144/6 = 24π sq. units.

The area of the unshaded region of the circle = (total area of the circle) - (the area of sector KLM) = (π*[tex]12^{2}[/tex]) - 24π = 120π sq units.

∴ The area of the unshaded region of the circle is 120π units squared.

Answer:

14.58 gallons

Step-by-step explanation:

The tank volume is 3360 in^3, which is the product of the base x length x height (14)(12)(29) = 3360 in^3.

We are given a conversion factor:  1 fluid oz = 1.8 in^3

We can write this as (1 fluid oz)/( 1.8 in^3).

Use this conversion factor to confert volume to fluid oz:

(3360 in^3)*((1 fluid oz)/( 1.8 in^3)) = 1867 fluid oz

There are 128 fluid oz/gallon.  Make this into a conversion factor:

(1 gallon/128 fluid oz)  [The conversion factor can be written with oz or gallon on the top - it makes no difference since the two values are equal to each other]

(1867 fluid oz)*((1 gallon/128 fluid oz) = 14.58 gallons

water  the tank will hold = 14.583 gallons

Given : A fish tank  has a volume = 3360 cubic Inches.

        The length of the tank is =14 inches

                             the width is  = 12 inches.

         The height of the tank is = 20 inches.

           If one fluid ounce is = 1.8 cubic inches

Volume of tank = 14 * 12 * 20  =  3360 cubic inches

1.8 cubic inches   =  one fluid ounce

3360 cubic inches   =  3360/1.8   fluid ounce

= 5600/3    fluid ounce

As we know,

                  1 gallons  = 128   fluid ounces

water  the tank will hold    =(  5600/3 ) / 128

                                           = 175 / 1 = 14.583 gallons

Therefore, water  the tank will hold  = 14.583 gallons

Answer:

y = 0.75x + 17

Step-by-step explanation:

y - 20 = 0.75(x-4)

y - 20 = 0.75(x) + 0.75(-4)

y - 20 = 0.75x -3

y = 0.75x -3 + 20

y = 0.75x + 17

y - 20 = 0.75(x - 4)    |add 20 to both sides

we can simplified equation:

use the distributive property: a(b + c) = ab + ac

y = 0.75x - 0.75 · 4 + 20

y = 0.75x - 3 + 20

Part 1

By the inscribed angle theorem, arc ZY measures 76 degrees.

Part 2

Since angles inscribed in the same arc are congruent, angle YXZ measures 38 degrees.

Part 3

Since diameters form semicircles and the arc of a semicircle measures 180 degrees, arc XYZ measures 180 degrees.

Part 4

Subtracting arc ZY from arc XYZ, we get 104 degrees.

Step-by-step explanation:

since DE is parallel to the diameter RS, D and E are just a transformation of R and S, where R and S slid up the same distance on the circle arc.

therefore, RD = SE.

and therefore d is half of the supplementary angle to the angle DE (that means together the angle DE and the supplementary angle are 180°).

so,

d = (180 - 50)/2 = 130/2 = 65°

22/7 was considered while choosing the square's side length, the area of just one side of the remaining paper which is a multiple of 7.

Since the largest circle that can be encircled by a square has a diameter "d" equal to its side length, we may use "d" to conveniently calculate both the square's area and the circle's area.

The largest possibly circle has been cut from a piece of paper.

Square’s area = [tex]d^2[/tex]

Circle’s area =ᴨ[tex]d^2/4[/tex]

Simplifying-

(divide both area by [tex]d^2[/tex]) we find their ratio is 1:(ᴨ/4) or 4/ᴨ (square: circle), and the inverse, ᴨ/4 circle: square.

Therefore diameter of circle =14 cm.

Hence area of circle=πr2.

If you use 22/7 as an approximation for ᴨ, the circle’s area 22/28 of the square’s, the square’s area is 28/22 of the circle’s , it follows that the area outside the circle is (28–22)/28 of the square’s area, which is (28–22)/28 x 14 x14,

or 6/28 x 14 x 14,

or 3/14 x 14 x 14,

or 42 square inches or-

(4-ᴨ)/4 x 14 x 14

Answer:

p, because Triangle ABC is similar to triangle EDC

Step-by-step explanation:

Angles DCA and DCE are vertical, so they are congruent.

Angles ABC and CDE measure 70°, so they are congruent.

Triangles BCA and DCE are similar by AA Similarity.

By corresponding angle of similar triangles, angles CED and BAC are congruent.

m<BAC = p

m<CED = m<BAC = p

m<CED = p

Answer:

D

Step-by-step explanation:

Looks like from the y-intercept of (0, 4), it goes to (1, 7). Therefore, it should be 3, or D.

(Just to make sure, you can plug it into the slope formula to get (7-4)/(1-0), which should give you 3!)

The triangles are not similar because their corresponding angles are not congruent to each other.

If two triangles are similar, their corresponding angles will be congruent to each other. Therefore, two triangles with congruent angles are either similar or congruent to each other. If they are similar, their corresponding sides will have proportional length.

From the image given, the angles of triangle ABC are:

C = 30

B = 90

A = 180 - 90 - 30 = 60.

Triangle LMN are:

L = 90
