The transformation maps rectangle QRST to Q'R'S'T' is reflection.

<h3>What is reflection?</h3>

An image will reflect through a line, known as the line of reflection. A figure is said to be a reflection of the other figure, then every point in a figure is at equidistant from each corresponding point in another figure.

As, 2 rectangles have identical side lengths and angle measures.

Also, second rectangle is a reflection of the first

and we know that the reflection of any shape done in a manner that it is equally reflected having identical side lengths and angle measures.

Evaluate \dfrac14c+3d

Crank

Answer: $\frac{45}{2}$

Step-by-step explanation:

<h3> The exercise is: " Evaluate $\frac{1}{4}c + 3d$ when $c = 6$ and $d = 7$ </h3>

Given the following expression:

$\frac{1}{4}c + 3d$

You can follow these steps in order to evaluate it:

1. Substitute $c = 6$ and $d = 7$ into the expression provided in the exercise:

$\frac{1}{4}(6) + 3(7)$

2. Solve the multiplications. Remember that:

$\frac{a}{b}*\frac{c}{d}=\frac{ac}{bd}$

Then:

$=\frac{6}{4} +21$

3. Reduce the fraction. Notice that the numerator 6 and the denomiantor 4 can be both divided by 2. Then:

$=\frac{3}{2} +21$

4. Solve the addition:

$=\frac{3}{2} +\frac{21}{1}$

Since the number 21 has a denominator 1, the Least Common Denominator is:

$LCD=2$

Then, the sum is:

$=\frac{3+42}{2}=\frac{45}{2}$

The pendulum of an antique clock has been damaged and needs to be replaced.If the original pendulum completed one swing every 1.

baherus [9]

Answer:

The length of pendulum is 55.853cm

Step-by-step explanation:

We are given

the original pendulum completed one swing every 1.5 seconds

so, T=1.5 sec

now, we can use time period formula

$T=2\pi \sqrt{\frac{l}{g} }$

l is the length of pendulum

g is acceleration due to gravity

$g=9.8m/s^2$

now, we can plug values

and then we can solve for l

$1.5=2\pi \sqrt{\frac{l}{9.8} }$

$\frac{l}{9.8}=0.05699$

$l=0.55853m$

In cm

$l=55.853cm$
