By using the SAS congruence rule, we can prove that AC = BD

What is SAS congruence Rule?

According to the SAS rule, two triangles are said to be congruent if any two sides and any angle between the sides of one triangle are equal to the corresponding two sides and angle between the sides of the second triangle.

What is CPCT?

When we study the congruent triangle, we come across the term CPCT. Corresponding Parts of Congruent Triangles are abbreviated as CPCT. Congruent triangles have equal corresponding parts, as is well known. We frequently use the abbreviation cpct in short terms rather than the complete form while discussing triangle topics and answering inquiries.

In the given figure, we have:

ABCD is a quadrilateral, where AB=DC and ∠DAB=∠CDA

Construction: Joining the two diagonal AC and BD;

Now,

In △ABD and △BAC;

⇒AB=DC                       [ Given ]

⇒  ∠DAB=∠CDA          [ Given ]

⇒  AB=BA            [ Common side ]

∴  △ABD≅△BAC         [ SAS Congruence rule ]

So,

AC = BD, by CPCT;

The unit rate of the fraction 2/3 will be 0.67 (approx.).

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following fraction -

2/3

Assume the fraction to be m = 2/3. So, we can write -

2 = 3m

We can write it as -

y = mx      ....Eq[1]

for [y] = 2

[x] = 3

We have to find the slope of the straight line represented by equation [1] for x = 3 and y = 2. We can proceed -

2 = 3m

m = 2/3

m = 0.67 (approx.)

Therefore, the unit rate of the fraction 2/3 will be 0.67 (approx.).

The graph of the function f is shown in the figure above. The value of lim ƒ(1-x²) is 1. Therefore, the correct option is option A.

In mathematics, a function is a phrase, regulation, or statute that establishes the connection between an independent variable and a dependent variable.

In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. The German mathematician Peter Dirichlet initially offered the contemporary definition of function in 1837.

Lim f(1 - x²) as x -> 0

Lim (1) - lim (x)²

The unit rate of 1/8 is 0.125 and the unit rate of 1/4 is 0.25.

What is the unit rate?

A unit rate is the price for one unit of something. This is written as a ratio with a denominator of one. For instance, if you ran 70 yards in 10 seconds, you averaged 7 yards per second. Both ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but only the latter is a unit rate.

For 1/8,

Divide the numerator and denominator by '8', to make the denominator 1.

                        [tex]=\frac{\frac{1}{8}}{\frac{8}{8}} \\\\\=\frac{0.125}{1} \\=0.125[/tex]

for 1/4,

Divide the numerator and denominator by '4', to make the denominator 1.

                            [tex]=\frac{\frac{1}{4}}{\frac{4}{4}} \\\\\\\=\frac{0.25}{1} \\\\=0.25[/tex]

The Equation used to determine the number of bottles produced in terms of the number of hours the plant is producing bottles is b = 1500h

Number of soda produced in 8 hours = 12000

We know

The number of soda produced varies directly with the hours works

Consider the number of bottle produced = b

Number of hours = h

Then the relationship will be b directly proportional to h

b ∝ h

b = k × h

Where k is the constant

Then substitute the values in the equation and find the value of k

12000 = k × 8

k = 12000/8

k = 1500

According to the diagram, angle BCD is exterior angle and angles BAC & ABC are remote interior angles of the triangle ABC.

As we know, the exterior angle is the sum of remote interior angles.

Answer:

x = 12

Step-by-step explanation:

Exterior Angle Theorem

The interior angles of a triangle sum to 180°. Angles on a straight line sum to 180°. Therefore, the exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.

Given angles:

Apply the exterior angle theorem and solve for x:

[tex]\implies m \angle BCD=m \angle BAC+m \angle ABC[/tex]

[tex]\implies 6x+2=3x+15+2x-1[/tex]

[tex]\implies 6x+2=3x+2x+15-1[/tex]

The simplified expression for the given functions f and g is 11-x

What is the value of the function?

The value of the function at a point can be found by substituting the point in the function. This value also depend on the nature of the Function.

We are given a function

f(x) =6-x

Now when we say f(2x) it means the x in the function should be replaced with 2x

Hence the function becomes

f(2x) =6-2x

Similarly

g(x) = (x/3)+8

g(3x-9)= (3x-9/3)+8

g(3x-9)= x-3+8

g(3x-9) = x+5

Now solve the equation:

The equation of g(x) after the translation up is g(x) = 4x² - 10

The given parameter represents the function f(x) in the question.

This function is given as

f(x) = 4x² - 13

The translation is given as

3 units up.

i.e. a translation up by 3 units

Mathematically, this can be represented as

(x, y) = (x, y + 3)

So, we have

g(x) = f(x) + 3

Substitute the known values in the above equation, so, we have the following representation

g(x) = 4x² - 13 + 3

Evaluate the like terms

g(x) = 4x² - 10

The average rate of change in white blood cells between days 1 and 5 is -29.75 mm³/day.

Given that

The function f(x)=5000(0. 98)0. 3x represents the number of white blood cells.

We need to evaluate this, for this

f ( x ) = 5000 * ( 0.98 ) ^(0.3 x)

f ( 1 ) = 5000 * 0.98^(0.3) = 5000 * 0.99396 = 4,969.788

f ( 5 ) = 5000 * 0.98 ^(5*0.3) = 5000 * 0.98^(1.5) = 5000 * 0.97 = 4,850.753

Average rate of change:

( 4,850.753 - 4,969.788 ) / ( 5 - 1 ) = - 29.75

Let the missing part be x.

According to triangle proportionality theorem we have:

The three  numbers are -5, -15, and -10 .

Equations of straight lines and equations of degree less than 1 are called "linear equations". The linear equation formula can be written as Y = mx + b. where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slope indicates the direction and slope of the line. This is because (0,y) is the point where the line intersects the y-axis.

c=b+5

b-2c=5

b-2(b+5)=5

b-2b-10=5

⇒The answer is 84

Answer:

see explanation

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are in proportion.

(a)

[tex]\frac{PQ}{AB}[/tex] = [tex]\frac{RS}{CD}[/tex] ( substitute values )

[tex]\frac{PQ}{6}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )

8 × PQ = 72 ( divide both sides by 8 )

PQ = 9 cm

(b)

[tex]\frac{AD}{PS}[/tex] = [tex]\frac{CD}{RS}[/tex] ( substitute values )

[tex]\frac{AD}{10.5}[/tex] = [tex]\frac{8}{12}[/tex] ( cross- multiply )

12 × AD = 84 ( divide both sides by 12 )

AD = 7 cm

(c)

given 2 similar figures with ratio of sides = a : b , then

ratio of areas = a² : b²

here ratio of sides CD : RS = 8 : 12 = 2 : 3

then ratio of areas = 2² : 3² = 4 : 9

let the area of PQRS be x , then using proportion

[tex]\frac{4}{48}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 432 ( divide both sides by 4 )

x = 108

then area of PQRS = 108 cm²
