Pls help i need this to get my grade up

vekshin1

Answer:

B

Step-by-step explanation:

So first I solved for y. The angle boc and cod together have to be 180 degrees so I subtracted 180 from 45 and then divided by 5. I got 27. Then since I knew what y was I could solve x. Since 5 times 27 is 135. I just plugged in 22 and 23 and realized it had to be 22.

RAISE THAT GRADE!! you got this I hope this helps!

1)The graph of the function y = 4x does not pass through the origin.

Gemiola [76]

Answer:

The correct options are:

Option B) $4^x$ is never zero.

Option F) When x=0, y≠0

Step-by-step explanation:

Consider the provided function.

$y=4^x$

When we substitute x=0 in above function we get:

$y=4^{0}$

$y=1$

When we substitute x=-1 in above function we get:

$y=4^{-1}$

$y=0.25$

When we substitute x=1 in above function we get:

$y=4^{1}$

$y=4$

The above function is exponential function which does not pass through the origin and the range of the function is a positive number.

The graph of the function is shown in figure 1.

Now consider the provided options.

Option A) $4^x$ is always greater than or equal to 1.

The option is incorrect as the value of the function is less than 1 for negative value of x.

Option B) $4^x$ is never zero

The option is correct.

Option C) When y=0, x=0

The option is incorrect.

Option D) When x=0, y=4

When x=0 the value of y is 1.

Thus, the option is incorrect.

Option E) $4^x$ is zero when x=0

When x=0 the value of $4^x$ is 1.

Thus, the option is incorrect.

Option F) When x=0, y≠0

The option is correct as 0≠1.

3. PLEASE HELP! Jenna just opened a checking account at the bank. Within the first month, she deposited three checks for $34.98,

sashaice [31]

Answer:C) She would have $216.88.

Step-by-step explanation:

A) Deposits: +34.98; +51.02; +51.22

Withdrawals: -5.23; -5.22; -7.89

B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22

The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.

98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88

In the triangle below, 4/5 represents which ratio?

ASHA 777 [7]

<span><u><em>Answer:</em></u>
sin (C)

<u><em>Explanation:</em></u>
<u>In a right-angled triangle, special trig functions can be applied. These functions are as follows:</u>
sin (theta) = </span> $\frac{opposite}{hypotenuse}$
<span>
cos (theta) = </span> $\frac{adjacent}{hypotenuse}$
<span>
tan (theta) = </span> $\frac{opposite}{adjacent}$ <span>

<u>Now, let's check the triangle we have:</u>
<u>We have two options:</u>
<u>First option:</u>
5 is the hypotenuse of the triangle
4 is the side adjacent to angle B
Therefore, we can apply the <u>cos function</u>:
cos (B) = </span> $\frac{4}{5}$ <span>

<u>Second option:</u>
5 is the hypotenuse of the triangle
4 is the side opposite to angle C
Therefore, we can apply the <u>sin function</u>:
sin (C) = </span> $\frac{4}{5}$
<span>
Among the two options, the second one is the one found in the choices. Therefore, it will be the correct one.

Hope this helps :)
