5 0

Answer:

The right triangle: The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.

A line that includes the points (k,7) and (0,8) has a slope of 1 7 . What is the value of k?

Shalnov [3]

value of k is $k=\frac{-1}{17}$

Step-by-step explanation:

We are given points (k,7) and (0,8) has a slope of 1 7 . What is the value of k?

The formula to find the slope given two points is:

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

where x₁ = k, y₁=7, x₂=0, y₂=0

Putting values:

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\17=\frac{8-7}{0-k}\\17=\frac{1}{-k}\\Multiplying\,\,both\,\,sides\,\,by\,\,-k\\17*-k=1\\Divide\,\,by\,\,17\\-k=\frac{1}{17}\\ k=\frac{-1}{17}$

So, value of k is $k=\frac{-1}{17}$

Paul deposited $95,000 in a savings account that pays 4% interest compounded daily. What is his balance at the end of six months

Arada [10]

Answer:

$\$96,919.02$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=6/12=0.5\ years\\ P=\$95,000\\ r=4\%=4/100=0.04\\n=365$

substitute in the formula above

$A=95,000(1+\frac{0.04}{365})^{365*0.5}$

$A=95,000(1+\frac{0.04}{365})^{182.5}=\$96,919.02$

-10 F is colder than -4 degrees?

Aleks04 [339]

Answer: yes, it is a smaller temperature, which means that is "colder"

Step-by-step explanation:

I guess that the question is:

Is -10°F colder than - 4°C?

Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:

T' = (T*9/5) + 32°

Replacing T by the temperature in celcius, we get:

T' = (-4°*9/5) + 32° = 24.8°F

This means that -4°C is equivalent to 24.8°F

And -10°F is a smaller value than 24.8°F (which mean that is colder)

This implies that -10°F is colder than -4°C

Then the statement is true.
