Resposta:
Per a càrrega de 680Ω: 7,27 volts
Per a les dues càrregues de 220Ω: 2,36 volts cadascuna
Explicació:
Segons la llei d’ohms
E = IRt
E és la força electromotriu = 12V
I és el corrent total que circula al circuit
Rt és la resistència equivalent total
Com que els 680Ω, 220Ω i 220Ω estan en sèrie;
Rt = 680 + 220 + 220
Rt = 1120Ω
Obteniu el corrent total del circuit:
Recordem que: E = IRt
I = E / Rt
I = 12/1120
I = 0,0107A
Tingueu en compte que el mateix corrent flueix a través de resistències connectades en sèrie, però tensions diferents.
Obteniu les tensions individuals;
Per a càrrega de 680Ω;
V = IR
V = 0,0107 * 680
V = 7,27 Volts
Per a la càrrega de 220Ω
V = IR
V = 220 (0,0107)
V = 2,36 volts
Per tant, les tensions de les dues càrregues de 220Ω seran de 2,36 volts cadascuna

Explanation:
From the question, we are informed about Alexandra who wants to create a math game in which users have to correctly answer mathematical problems. She wants the game to solve a randomly created problem and then indicate if the player's answers are correct or incorrect. In this case the way Alexandra will get the program to solve mathematical problems is for her to write an algorithm, so that the computers can follow series of step-by-step instructions to get the equation solved. An algorithm in computer is often created as function, it can be regarded as a step-by-step instructions that are put in place to carry out specific task. This can range from simple process to complex operation, simple operation such as addition or multiplication of numbers and complex operation that involves playing of video file that is compressed.

What is the average rate of change of h(x)=2^{x+1}h(x)=2 x+1 h, (, x, ), equals, 2, start superscript, x, plus, 1, end superscript over the interval [2,4][2,4]open bracket, 2, comma, 4, close bracket?
Answer:
Average Rate = 12
Explanation:
Given
h(x) = 2^(x + 1)
Interval = [2,4]
Required
Determine the average rate of change
The average rate of change of h(x) is calculated using.
Average Rate = (h(b) - h(a))/(b - a)
Where
[a,b] = [2,4]
Meaning a = 2 and b = 4
So, the formula becomes:
Average Rate = (h(4) - h(2))/(4 - 2)
Average Rate = (h(4) - h(2))/2
Average Rate = ½(h(4) - h(2))
Calculating h(4)
h(4) = 2^(4+1)
h(4) = 2⁵
h(4) = 32
Calculating h(2)
h(2) = 2^(2+1)
h(2) = 2³
h(2) = 8
So, we have:
Average Rate = ½(h(4) - h(2))
Average Rate = ½(32 - 8)
Average Rate = ½ * 24
Average Rate = 12
Hence, the average rate of change is 12
Jason has decided to use his name on all the images to protect them from misuse. He has also decided to use the logo of his company across all
the images to be extra sure about its protection in the digital world. Select the phrases or sentences that describe the two types of watermarking
options has he used to get the results.
Types of Watermarking Options
Jason wants to tag his name or logo somewhere on the image, preferably in the corner of the photo. He uses an online editing tool to add his
name at the corner of the image. He can prevent misuse of his Images online by adding a watermark over the image. Text watermarking
involves adding the imageer's name at the corner of the image. This is usually done with the help of online editing tools or software. In this form
of watermarking, he can use the logo of his company over the image to protect his identity.
Just to be sure, Jason also uses tiled watermarking, which involves placing his company logo in a pattern spread across the image. First, he
creates a copy of the original. This is to make sure that the watermarked version is saved separately. If needed, he can always access the
original image. Then he opens the logo that he wants to use as the watermark, coples It, and pastes it onto a new layer, above the image. He
turns down the opacity of the layered image. Then he merges the layer to join the watermark with the image.

Answer:
From the side.

Answer:
Explanation:
