Answer:

SAS

Step-by-step explanation:

.. cuz, it just is c:

By ''SAS congruency'' theorem we can prove AD = CB.

We have to given that,

In a figure,

AB = CD

∠1 = ∠4

Now, In triangle ADC and triangle ABC,

AC = AC (Common side)

∠1 = ∠4  (Given)

AB = CD (Given)

Hence, By SAS Congruency theorem,

Δ ADC ≅ Δ ABC

So, We get;

AD = CB

Answer:

27.54

Step-by-step explanation:

73% can be considered 73/100

So,

73/100 x $102 = $74.46 is the amount of money marked down.

102 - 74.46 = $27.54

Based on the information provided, the missing number would be number 6.

When it comes to finding missing numbers, the first step is to decipher or identify the pattern. This can be either a sequence of numbers or the application of a specific mathematical operation such as subtraction or addition.

In this case, we can see there is a sequence of numbers that seems to go from 1 to 9. However, if you check carefully, the number 6 is missing, which is the number you need to add.

Answer:

We proceed to use the following operations: (i) Vertical translation downwards (\(k = -\frac{1}{2}\)), (ii) Vertical compression (\(c = \frac{1}{2}\)), (iii) Vertical translation upwards (\(k = \frac{1}{2}\)). The graph is presented below.

Step-by-step explanation:

To transform \(y = \frac{5}{4}\cdot x + \frac{1}{2}\) into \(y = \frac{5}{8}\cdot x + \frac{1}{2}\), we apply the following steps:

(i) Vertical translation downwards (\(k = -\frac{1}{2}\))

\(g(x) = f(x) +k\) (1)

(ii) Vertical compression (\(c = \frac{1}{2}\))

\(g(x) = c\cdot f(x)\) (2)

(iii) Vertical translation upwards (\(k = \frac{1}{2}\))

\(g(x) = f(x) + k\)

Now, we proceed to transform the primitive expression:

Step 1

\(f'(x) = \frac{5}{4}\cdot x\)

Step 2

\(f''(x) = \frac{5}{8}\cdot x\)

Step 3

\(g(x) = \frac{5}{8}\cdot x + \frac{1}{2}\)

The graph of both function are now presented below. The parent function is the red line and the new function is represented by the blue line.

C: 22

Step-by-step explanation:

So for this problem, I have a very simple method to solve it. Just count the squares. It's as easy as that. The number of full squares I counted were 18, and I saw a little bit here and there, so I rounded the extra pieces to 22.

Answer: D

Step-by-step explanation:

a.) 0.5367 feet

b.) 0.5223 feet'

Given the rate at which an eucalyptus tree will grow modelled by the equation 0.5+6/(t+4)³ feet per year, where t is the time (in years).

The amount of growth can be gotten by integrating the given rate equation as shown:

\(\int\limits {0.5} \, + \frac{6}{(t+4)^{3} } dt\)

\(=\int\limits {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx\)

\(=0.5t+\int\limits6u^{-3} du \, \,where \,u=t +4 \, and \, du=dt\)

\(=0.5t+6*\frac{u^{-3} }{-2} + C\)

\(=0.5t-3u^{-2}+C\)

\(=0.5t-3(t+4)^{-2} +C\)

a)  The number of feet that the tree will grow in the second year can be gotten by taking the limit of the integral from  t =1 to t = 2

\(\int\limits^2_1 {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx \, =[0.5t-3(t+4)^{-2} ]\)

\(=[0.5(2)-3(2+4)^{-2} ]-[0.5-3(5)^{-2} ]\)

\(=\frac{11}{12}-\frac{1}{2}-\frac{3}{25}\)

\(=0.9167-0.5+0.12\)

\(=0.5367\)

b)  The number of feet that the tree will grow in the third year can be gotten by taking the limit of the integral from  t =2 to t = 3

\(\int\limits^3_2 {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx \,\)

\(=[0.5t-3(t+4)^{-2} ]\)

\(=[1.5-\frac{3}{49} ]-[1-\frac{1}{12} ]\)

=1.439-0.9167

=0.5223 feet

The figure has different measure in all their parts, then, it has no reflectional symmetry.

For a point symmetry evey part has matching part, the same distance form a central point but our figure has the same 2 ellipses but with different measure. The figure dont have rotational symmetry because there is a little ellipse in the middle of the others.

Answer:

slope (m) = 2/3

Step-by-step explanation:

slope = change in x /change in y

Also, slope is y2 - y1 / x2 -x1. That is what I apply for this activity, hence:

slope = 3 - (-1) / 0 - (-6)

         = 3 + 1 / 0 + 6

         = 4 / 6

         = 2/3

∴ slope(m) = 2/3

250 grams of dragon alloy #11 and 750 grams of dragon alloy #35 is needed to make 1000 grams (1 kg) of Dragon alloy #17.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount of alloy #11 and y represent the amount of alloy #15, hence:

(0.36x) + (y * 0.36) = 1(0.36)   (1)

Also:

0.28x + 0.64y = 1(0.55)    (2)

From both equations:

x = 0.25, y = 0.75

Step-by-step explanation:

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!

Day 1: 100 (3 tagged)

Day 2: 97 (3 tagged)

100+97=197

\(x = \frac{3}{4} + \frac{ \sqrt{105} }{4} \: \: , \: \: \: x = \frac{3}{4} - \frac{ \sqrt{105} }{4} \\ \)

Step-by-step explanation:

2x² - 3x - 12 = 0

Using the quadratic formula which is

\(x = \frac{ - b \pm\sqrt{ {b}^{2} - 4ac} }{2a} \\ \)

From the question

a = 2 , b = - 3 , c = - 12

So we have

\(x = \frac{ - - 3\pm \sqrt{ ({ - 3})^{2} - 4(2)( - 12)} }{2(2)} \\ = \frac{3\pm \sqrt{9 + 96} }{4} \\ = \frac{3\pm \sqrt{105} }{4} \: \: \: \: \: \: \)

The length of m is 15.6 cm.

A point where two lines meet produces an angle.

The breadth of the "opening" between these two rays is referred to as a "angle". It is depicted by the figure.

Radians, a unit of circularity or rotation, and degrees are two common units used to describe angles.

By connecting two rays at their ends, one can make an angle in geometry. The sides or limbs of the angle are what are meant by these rays.

The limbs and the vertex are the two main parts of an angle.

The common terminal of the two beams is the shared vertex.
