Divide 2 by 5 to get a decimal, then multiply the decimal by 100 to get a percent.

2/5 = 0.4

0.4x100 = 40

2/5 = 40%

Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?
Fudgin [204]

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

||x-4||, we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

||x-4||

Hence it follows that option C is right.

Andrei [34K]

elg=124°

eld=2x

elg+eld=180°=>eld=180°-124°=56°/eld=2x=56°=>x=56°/2=28°

eld+dlh=180°=>dlh=180°-56°=124°

hlg+dlh=180°=>hlg=180°-124°=56°

Gonzalez Manufacturing borrowed ​$. Part of the money was borrowed at ​%, part at ​%, and part at ​%. The annual interest was ​$
Pavel [41]

Answer:

The answer is "rate 12%, 14%, 16% and value 4000, 10000, and 7000".

Step-by-step explanation:

Let the value is x, y, and z. so,

The value of x amount will be borrowed at 12% = \frac{12}{100} \times x= 0.12x

The value of y amount will be borrowed at 14%= \frac{14}{100} \times x= 0.14x

The value of z amount will be borrowed at 16% = \frac{16}{100} \times x= 0.16x

If the total amount= 21000

\to x+y+z=21000

If the total interest= 3000

calculating the total interest:

\to 0.12x +0.14y +0.16z = 3000

The overall amount borrowing at 12% and 14% was half as much as the amount borrowed at 16%.

\to x + y = 2z\\\\\to x + y - 2z = 0

by calculating the value we have  3 equations that are:

\to x+y+z=21000\\\\\to 0.12.x +0.14.y +0.16z = 3000\\\\\to  x + y - 2z= 0\\

calculate the matrix by above-given value:

\left[\begin{array}{ccc}1&1&1\\0.12&0.14&0.16\\1&1&-2\end{array}\right]\left[\begin{array}{c}x&y&z\\ \end{array}\right] =\left[\begin{array}{c}21000&3000&0\\ \end{array}\right]

by solving the above matrix we get:

\left[\begin{array}{c}x&y&z\\ \end{array}\right] =\left[\begin{array}{c}4000&10000&7000\\ \end{array}\right]

\to \$ 4000 \text{ lent at} 12 \% \\\to \$ 10000 \text{ lent at} 14 \% \\\to  \$ 7000 \text{ lent at} 16\%\\\\
