Answer:

25y^2

Step-by-step explanation:

Answer:

X=29°

Step-by-step explanation:

Since triangles ABC and DEC are congruent, Angle A = Angle D = 74°

Sum of all angles in a triangle is 180°

So, Angle A + Angle B + Angle C =180°

74°+2X+48°=180°

2X=180°-122°

2X=58°

X=29°

======================================================

Explanation:

When it comes to congruence statements like this, the order of the letters is important. This is so we pair up the letters properly.

ABC has A first, B second, C third

DEC has D first, E second, C third

So we have these pairings

Which leads to

Due to the fact that congruent triangles have congruent corresponding parts.

Since B = E and B = 2x, we can say that E = 2x by either substitution or the transitive property. Both effectively say the same thing.

---------------------------

Now focus on triangle CDE

The three angles we have are

Those three angles add to 180. This is true for any triangle.

C+D+E = 180

48+74+2x = 180

122+2x = 180

2x = 180-122

2x = 58

2x = 58/2

x = 29

--------------------------------

Side note: since x = 29, this means angle B = 2x = 2*29 = 58, and this is the measure of angle E as well.

We can check the answer by doing C+D+E = 48+74+58 = 180. So we have confirmed the answer.

Answer:

the answer is -3 1/4

Step-by-step explanation:

The additive Inverse of 3 1/4​ will be - 3 1/4.

Suppose that the given function is [tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

We are given the number as;

3 1/4​ = 13/4

Therefore, the additive Inverse of 3 1/4​ will be;

Negative 13/4 = - 3 1/4

Hence, the additive Inverse of 3 1/4​ will be - 3 1/4.

Answer:

124200

Step-by-step explanation:

Answer:

x=9

Step-by-step explanation:

f(x) = −(x − 7)2 + 4

(substitute f(x) = 0)

0= −(x − 7)2 + 4

(distribute 2 into brackets)

0= −(2x - 14) + 4

(remove brackets and change the sign of each expression inside the brackets)

0= - 2x + 14 + 4

(add the numbers)

0= - 2x + 18

(move variable to the other side and change its sign)

2x = 18

(divide both sides by 2)

x = 9

The given expression is quadratic, parabolic graph, relative maxima and real zeros. The correct options are (a), (c) and (f).

The general form of a quadratic equation is given as ax^2 + bx + c = 0.

Here, a ≠ 0 and b and c are integers.

The degree of a quadratic equation is 2.

The given expression is f(x) = -(x - 7)² + 4

Since the degree of the expression is 2, it is quadratic.

The graph of the given equation will be parabolic.

By comparing from the general vertex form (x - h)² + k, its vertex can be found as (7, 4).

Axis of symmetry is x = 7.

y-intercept can be obtained by plugging x = 0 as,

-(0 - 7)² + 4 = 53.

Maxima or minima can be found as below,

f'(x) = 0

⇒ -2(x - 7) = 0

⇒ x = 7

In order to find the solution write the expression as follows,

-(x - 7)² + 4 = 0

⇒ -x² + 14x - 49 + 4 = 0

⇒ x² - 14x + 45 = 0

⇒ x = 5,9

Thus, the equation has real solutions.

Hence, the properties of the given equation are derived as quadratic, parabolic graph, relative maxima and real zeros.

Answer:

40 degrees

Step-by-step explanation:

It would be 40 degrees because every triangle will add up to 180 degrees. Angle Q and R are equal (pulled from the sign that the two lines from P are equal) So 180 - 70 = 110 - 70 = 40

The measure of angle P is 55 degrees.

The given image is an isosceles triangle. An  isosceles triangle is a three sided polygon that has two equal angles. Angles in a triangle add up to 180 degrees.

The triangle is an  isosceles triangle because of the two lines on the triangle.

<p + <r + <q = 180 degrees

70 + <r + <q = 180

<r + <q = 180 - 70

<r + <q = 110

<r + <q = 110/2 = 55

box 2 (right one): 18*4*10=720

720+810=1,530

Answer:

1530 cm^3

Step-by-step explanation:

They are two Rectangular Prism.

prism 1.

length l = 18 cm

width w = 10 cm

height h = 4 cm

diagonal d = 20.976177 cm

total surface area S_tot = 584 cm^2

lateral surface area S_lat = 224 cm^2

top surface area St_op = 180 cm2

bottom surface area S_bot = 180 cm^2

volume V = 720 cm^3

Prism 2.

length l = 10 cm

width w = 9 cm

height h = 9 cm

diagonal d = 16.1864141 cm

total surface area S_tot = 522 cm^2

lateral surface area S_lat = 342 cm^2

top surface area Stop = 90 cm^2

bottom surface area Sbot = 90 cm^2

volume V = 810 cm^3

Add 720 cm^3+810 cm^3 = 1530 cm^3

Agenda: l = length

w = width

h = height

d = diagonal

S_tot = total surface area

S_lat = lateral surface area

S_top = top surface area

S_bot = bottom surface area

V = volume

Step-by-step explanation:

Answer: (-5,1)

Step-by-step explanation:

−2.5x+y=13.5

−2.5x+y+2.5x=13.5+2.5x(Add 2.5x to both sides)

y=2.5x+13.5

Step: Substitute

5x+13.5  and 2.25x−y=−12.25:

2.25x−y=−12.25

2.25x−(2.5x+13.5)=−12.25

−0.25x−13.5=−12.25(Simplify both sides of the equation)

−0.25x−13.5+13.5=−12.25+13.5(Add 13.5 to both sides)

−0.25x=1.25

−0.25=1.25−0.25(Divide both sides by -0.25)

x=−5

Step: Substitute−5forxiny=2.5x+13.5:

y=2.5x+13.5

y=(2.5)(−5)+13.5

y=1(Simplify both sides of the equation)

Answer:

x = -4, y = 3.5

Step-by-step explanation:

-2.5x + y = 13.5 ------ (1)

2.25x - y = -12.25 ---(2)

you can substitute (1) into (2) or vice versa

We are going to substitute (2) into (1)

but first we have to rewrite it in terms of x or y

Lets do y

from (2), (after subtracting -2.25x from both sides), y = 12.25 + 2.25x ----(3)

plug in (3) into (1)

-2.5x + (12.25 + 2.25x) = 13.5

-2.5x + 12.25 + 2.25x = 13.5

-2.5x + 2.25x = 13.5 - 12.5

-0.25x = 1

x = -(1/.25)

x = -4

Now we have x

We already used (2), lets plug in x = -4 into (1)

-2.5(-4) + y = 13.5

10 + y = 13.5

y = 13.5 - 10

y = 3.5

Answer:

Domain: [-4,4]

Step-by-step explanation:

Domain is representative of the space on the graph that x occupies. Because all the points are closed, there should be closed or inclusive brackets outside of the domain. Because the lowest inclusive point is -4, that should be the first domain point. The graph continues until -2, where that line stops, but the second line begins at -2, so we include this point too, and there is no need to mention it in the domain. The second line ends at 4, so that is the highest end of the domain and would be the second domain point. Therefore the domain is [-4, 4]. Remember to keep closed brackets because of the closed points.

−2(7−y)+4=−4

Simplify −2(7−y)+4.

2y−10=−4

Move all terms not containing y to the right side of the equation.

2y=6

Divide each term by 2 and simplify.

y=3

Answer:

80 milligrams

Step-by-step explanation:

The volume of bottle is 16-ounce, and the amount of vitamin C in the bottle is 200 mg.

Since the 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C, which is 250% of the daily recommended allowance of vitamin C for adults. Then for 100% of the daily alowence, we need to multiply 200/250 by 10. We get 80. The picture shows a dubble number line for paper homework. Good luck!
