Paladinen [302]3 years ago
5 0

Answer:

Increase of 20%

Step-by-step explanation:

change = new-old/old = 54 - 45/45 = 9/45 = 0.20

Because this is a positive number this was a percent increase.

%change = |change| * 100 = % = |0.20| * 100 = % = 20%

Therefore your answer is an increase of 20%

Hope this helps,

oksian1 [2.3K]

Answer:

YTM = 5.45%

Step-by-step explanation:

Here, we are interested in calculating the yield to maturity.

Mathematically;

Annual coupon=1000*4.3%=43

YTM=[Annual coupon+(Face value-Present value)/time to maturity]/(Face value+Present value)/2

=[43+(1000-870)/18]/(1000+870)2

=5.45%

If Marissa bakes 30 cookies every 15 minutes, how many cookies can Marissa make in 42 minutes?​
marissa [1.9K]

Answer:

84 cookies

Step-by-step explanation:

First, find the amount she bakes per minute. It is given that Marissa bakes 30 cookies every 15 minutes, or:

30 cookies/15 minutes = 2 cookies/minute.

Marissa bakes 2 cookies per minute. Multiply 2 with 42 minutes to find the total cookies baked in 42 minutes:

42 x 2 = 84

84 cookies is your answer.

Factor completely 3x^2+7x-6
Likurg_2 [28]
I find the following method easiest to factor this equation.

1. First, fill in what you know would be the factors for the first value, 3x^2.  The number 3 only has 2 factors: 3 and 1. Therefore, we know the first values are:

(3x _____)(x_____)

2. Next, figure out what the possible factors for the last value would be (-6). The following combinations are possible:
2 and -3 OR -3 and 2
-2 and 3 OR 3 and -2
-1 and 6  OR 6 and -1
1 and -6 OR -6 and 1

3. Plug in the combinations into step 1 and see which gives you the correct answer:
<span>(3x + 2)(x - 3) = 3x^2 - 7x - 6 --> no
</span>(3x - 3)(x + 2<span>) = 3x^2 + 3x - 6 --> no
</span>(3x - 2)(x + 3) = 3x^2 + <span>7x - 6 --> YES</span>

Find the slope of the line. m=
luda_lava [24]

Answer:

<em>m</em> = 0

Step-by-step explanation:

slope can be found using the following equation:

<em>m  </em>(slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-3 , -2)

(x₂ , y₂) = (1 , -2)

Plug in the corresponding numbers to the corresponding variables:

<em>m</em> =  (y₂ - y₁)/(x₂ - x₁) = (-2 - (-2))/(1 - (-3))

Simplify:

<em>m</em> = (-2 - (-2))/(1 - (-3)) = (-2 (+2))/(1 +3) = (-2 + 2)/(1 + 3)

<em>m</em> = (-2 + 2)/(1 + 3) = (0)/(4)

<em>m </em>= 0/4 = 0

The slope of the line is 0.
