Write an algebraic expression that models the situation “the piggy bank contained $25, and $1.50 is added each day.” Use d to re

present the number of days
a) 25d+1.5

b) 25+1.5d

c) 25d+1.5d

d) 25+(1.5)(7)d

the answer is b because the piggy bank originally contained $25 and the person adds $1.50 per day.. so: 25+1.5d

lin measured the diameter of a circle in two different directions. Measuring vertically, she got 3.5 cm, and measuring horizonta

IrinaVladis [17]

Answer:

Diameter of circle while measuring vertically=3.5 cm

Diameter of circle while measuring Horizontally=3.6 cm

As you have not written by which instrument from geometry box you have measured the length of diameter.

1. By Scale i.e ruler 2. By Divider Or 3. By mere Observation i.e by comparing length

1.If you have done measurement by simply observation there are maximum possibility of having error.

2. Then if you have measured these lengths by scale or ruler there is very less chances of getting error in measurement of length because sometimes divison in scale varies i.e if a point lies between 4.5 to 4.6 we can't say exactly whether it is 4.5 or 4.6.

3. So it is better to compare line segments by Divider.There is no chances of getting error.

Most probably you have measured Diameter by ruler, Due to that you have faced the problem.

What is the length of leg y of the right triangle?<br> 84<br> 85<br> O1<br> 09<br> O 13<br> O 26

Softa [21]

Answer:

$\boxed{\sf Length \ of \ leg \ y = 13}$

Step-by-step explanation:

Pythagoras theorem states that <em>“In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides”</em>.

$\therefore \\ \sf \implies {84}^{2} + {y}^{2} = {85}^{2} \\ \\ \sf {84}^{2} = 7056 : \\ \sf \implies 7056 + {y}^{2} = {85}^{2} \\ \\ \sf {85}^{2} = 7225 : \\ \sf \implies 7056 + {y}^{2} = 7225 \\ \\ \sf Substract \: 7056 \: from \: both \: sides : \\ \sf \implies (7056 - 7056) + {y}^{2} = 7225 - 7056 \\ \\ \sf 7056 - 7056 = 0 : \\ \sf \implies {y}^{2} = 7225 - 7056 \\ \\ \sf 7225 - 7056 = 169 : \\ \sf \implies {y}^{2} = 169 \\ \\ \sf 169 = {13}^{2} : \\ \sf \implies {y}^{2} = {13}^{2} \\ \\ \sf \implies y = \sqrt{ {13}^{2} } \\ \\ \sf \implies y = {13}^{ \cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ \sf \implies y = 13$

So,

Length of leg y of the right triangle = 13

Which is the graph of y= cos(x-pi)

marshall27 [118]

Answer:

graph attached

Step-by-step explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period $2\pi$ . If the point $(x,y)$ lies on the graph, point $(x+2k\pi ,y)$ will also lie on the graph where k is any integer.

Here,

$cos(x-\pi )=cos[-(\pi -x)]=cos(\pi -x)=-cos x$
