Answer:
Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:
We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:
Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side
and we simplify:
now it's easy to solve for t:
And thus we arrive to the solution.
Answer:
135°
Step-by-step explanation:
seg AB=seg OB
tan ∠AOB = 1
∠AOB = 45°
∠AOC = 135°
Answer:
100 ft²
Step-by-step explanation:
1 cm : 2 ft
1 cm² : 4ft²
25 cm² : X ft²
1/4 = 25/X
X = 25×4 = 100 ft²
Answer:
y = -5/4x +27/4
Step-by-step explanation:
"A line passes through the point (8, -1) and has a slope of -5/4
"
I'm guessing you want to formulate an equation.
To do that, we use the Slope-Intercept Form, y = mx + b, where m is the slope, and b is the y- intercept.
Since we know the slope, we can substitute -5/4 for slope.
y = -5/4x + b
To Find B, we will substitute the ordered pair (8,-1) as x and y.
8= -5/4(-1) + b
8 = 5/4 + b
Subtract 5/4 from both sides.
8-5/4 = 5/4-5/4 + b
27/4 = b
Substitute 27/4 as b in the equations.
<u>y = -5/4x + 27/4</u>
