Answer:

Step-by-step explanation:

The segment AC is the angle bisector of angle BAD and angle BCD.

A ray, segment, or line that divides a given angle into two equal angles is known as an angle bisector.

When something is bisected or bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.

here, we have,

Given that ΔABC ≅ ΔADC Prove: AC bisects ∠BAD and AC bisects ∠BCD​

From the given data it is concluded that all the corresponding angles of the triangle are equal to each other.

In the triangle ABC and ADC:-

∠BAC = ∠DAC

∠BCA = ∠DCA

From the above proof, it is concluded that the AC bisects ∠BAD and ∠BCD.

Therefore, the segment AC is the angle bisector of angle BAD and angle BCD.

Step-by-step explanation:

Answer:

28 meters wide

Step-by-step explanation:

This involves using the Pythagorean Theorem.

We know: a (the length)=96, b (the width)=?, c (diagonal distance)=100

a^2+b^2=c^2

96^2+b^2=100^2

9216+b^2=10000

b^2=784

b=28

The field is 28 meters wide

Answer:

- $5.5 per pound

- [tex]y = 5.5x[/tex]

Step-by-step explanation:

Given

$11 for 2 pounds

Solving (a): Cost per pound

This is calculated by dividing $11 by 2 pounds

[tex]Cost\ per\ pound = \frac{\$11}{2\ lb}[/tex]

[tex]Cost\ per\ pound = \$5.5/\ lb[/tex]

Hence, the cost per pound is $5.5 per pound

Solving (b): Represent as an equation.

If 1 pound costs $5.5 (as shown in (a))

Then

x pounds costs $5.5 * x

[tex]Cost = 5.5 * x[/tex]

[tex]Cost = 5.5x[/tex]

This cost is represented with y

[tex]y = 5.5x[/tex]

Answer:

14 integers

Step-by-step explanation:

Given

[tex]Range: -6.01\ to\ 7.75[/tex]

Required

Determine the number of integers

Integers implies numbers without decimals; it could be positive or negative or 0.

So, within the range: the integers are:

[tex]-6, -5, -4,-3,-2,-1,0,1,2,3,4,5,6,7[/tex]

Notice that the above numbers are integers within the given range.

By counting them, we get the required number of integers.

[tex]Numbers = 14[/tex]

Hence, there are 14 integers

Answer:

x = 90

y = 43

Step-by-step explanation:

[tex] In\: \triangle ABC\\

AB = AC.... (given)

\therefore m\angle ABC = m\angle ACB\\[/tex] (Property of isosceles triangle)

[tex] \because m\angle ACB = 47\degree \\

\therefore m\angle ABC = 47\degree \\

2y\degree + 47\degree+47\degree = 180\degree \\

2y\degree + 94\degree= 180\degree \\

2y\degree = 180\degree - 94\degree \\

2y\degree = 86\degree \\\\

y = \frac{86\degree}{2} \\\\

y\degree = 43\degree \\\\

\huge \purple {\boxed {y = 43}} \\\\[/tex]

x° + y° + 47°=180°

x° + 43° + 47°=180°

x ° + 90° = 180°

x ° = 180° - 90°

x° = 90°

x = 90

Answer:

square,rectangle,rhombus,paralellagram

Step-by-step explanation:

The pair of trigonometric functions that are equivalent is cos76°, sin14°.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

We know sin(π/2 - Ф) = cosФ and cos(π/2 - Ф) = sinФ.

sin23° = cos(90° - 23°) = cos67°.

cos41° ≠ sin41°.

cos58° = cos(180° - 58°) = cos122°.

cos76° = sin(90° - 76°) = sin14°.

Answer:

z=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(z−10)=−4

(2)(z)+(2)(−10)=−4(Distribute)

2z+−20=−4

2z−20=−4

Step 2: Add 20 to both sides.

2z−20+20=−4+20

2z=16

Answer:

The instantaneous rate of change as x approaches 3 is 18.

Step-by-step explanation:

From Differential Calculus and Geometry we remember that instantaneous rate of change of the function is represented by a tangent line, whose slope is determined by the first derivative of the curve. Let [tex]f(x) = 3\cdot x^{2}[/tex], the instantaneous rate of change of the function when x approaches 3 is deducted from the definition of derivative:

[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex] (1)

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x^{2}+2\cdot x\cdot h +h^{2})-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot x^{2}+6\cdot x\cdot h+3\cdot h^{2}-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{6\cdot x\cdot h +3\cdot h^{2}}{h}[/tex]

[tex]f'(x) = \lim _{h\to 0} (6\cdot x+3\cdot h)[/tex]

[tex]f'(x) = 6\cdot x \cdot \lim_{h\to 0} 1 + 3\cdot \lim_{h\to 0} h[/tex]

[tex]f'(x) = 6\cdot x[/tex] (2)

If we know that [tex]x = 3[/tex], then the instantaneous rate of change as x approaches 3 is:

[tex]f'(3) = 6\cdot (3)[/tex]

[tex]f'(3) = 18[/tex]

The instantaneous rate of change as x approaches 3 is 18.

Step-by-step explanation:

First you have to find the mean of 22, 13, 17, 16, and 17, by first adding 22, 13, 17, 16, and 17 to get 85. Because mean is the numbers added up divided by the total amount of numbers, there are 5 numbers and then you have to divided 85 by 5.

After you get the mean of these numbers, find the other number which will level the mean to 17.
