the desert temperature, h, oscillates daily between 40°f at 5am and 80°f at 5pm. write a possible formula for h, measured in hours from 5am, using the form h
The desert temperature, h, oscillates daily between 40°f at 5am and 80°f at 5pm. write a possible formula for h is - [tex]H(t) = -20 cos \frac{pi}{12} t + 60[/tex]
y = A cos[B(x-C)] + D, where
A = amplitude,
period = 2π / |B|
C = Phase shift
D = vertical shift
Amplitude = (Max value - Min value) / 2
Amplitude = 80 - 40 / 2
Amplitude = 20
24 = 2π / |B|
B = π / 12
vertical shift = Max value + Min value / 2
D = 80 + 40 / 2
D = 60
Since the temp. is min. at t = 0, we will use negative cosine.
H(t) = -20 cos(π t/ 12) + 60
∴ Our required equation will be - [tex]H(t) = -20 cos \frac{pi}{12} t + 60[/tex]

when abby was young her father marked her height on the door frame every month. abby’s father noticed that between the ages of one and three, he could predict her height (in inches) by taking her age in months, adding 75 inches and multiplying the result by one-third. determine her predicted height on her second birthday.
The predicted height on Abby's second birthday is 33 inches
Calculating height
From the question, we are to determine Abby's predicted height on her second birthday
From the given information,
Abby's father could predict her height (in inches) by taking her age in months, adding 75 inches and multiplying the result by one-third
On her second birthday,
Abby is 2 × 12 months = 24 months old
Thus, her height on her second birthday is
(24 + 75) × 1/3
= 99 × 1/3
= 33 inches
Hence, the predicted height on Abby's second birthday is 33 inches

Please answer the circled questions! (And also part a and b)
A. When Steven buys 2.32 pounds of trial mix and 4.64 pounds of dry fruit, the cost is $27.84.
B. When Mario got $0.40 in change from buying trail mix The pounds bought will be 5.6 pounds.
How to illustrate the information?A. It should be noted that Steven buys 2.32 pounds of trial mix and 4.64 pounds of dry fruit. The cost will be:
= (2.32 × $3.50) + (4.64 × $4.25)
= $8.120 + $19.72
= $27.84
B. From the information, Mario got $0.40 in change from buying trail mix The pounds bought will be:
20 - 3.50x = 0.40
3.50x = 20 - 0.40
3.50x = 19.60
x = 19.60 / 3.5

if angle a and angle b are supplementary angles and m∠a=x, which expressions represents the number of drgress in angle B? x-180, 180-x, x-90, 90-x
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.
Which expressions represent the number of degrees of angle B?
Two angles A and B are supplementary only if their measures add up to 180 degrees.
Then we can write the simple equation:
m∠A + m∠B = 180°
In this case, we know that we have two angles a and b that are supplementary, and the measure of angle a is equal to x, where x is a variable, then using the above equation we can write:
m∠a + m∠b = 180°
Replacing the measure of angle a by the variable we get:
x + m∠b = 180°
Solving this for the measure of angle b we get:
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.

The equivalent expression for the expression (-5cd-4)(2cd²)² is - 20c³d⁵ - 16c²d⁴.
A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Consider the expression,
(-5cd - 4)( 2cd²)²
Now let x = (-5cd - 4)( 2cd²)²,
Then,
x = (-5cd - 4)( 2cd²)²
x = ( - 5cd -4 ) × (2c)² × (d²)²
x = ( - 5cd - 4) × ( 4c² ) × d⁴
x = ( -5cd - 4 ) × 4c²d⁴
Using the distributive property,
x = ( - 5cd ) × ( 4c²d⁴ ) - 4 × 4c²d⁴
x = - 20 × c³ × d⁵ - 16 × c²d⁴
x = - 20c³d⁵ - 16c²d⁴

A line that includes the points (c, -2) and (-1, 0) has a slope of -1/3 What is the value of c?
Answer:
c = 5
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]\large\boxed{y=mx+b}[/tex]
where:
m is the slope.b is the y-intercept.Given:
Slope = -¹/₃Point = (-1, 0)Substitute the given slope and point into the formula and solve for b:
[tex]\begin{aligned}y & = mx + b\\\implies 0 & = -\dfrac{1}{3}(-1)+b\\0 & = \dfrac{1}{3}+b\\-\dfrac{1}{3}&=b\\ \implies b&=-\dfrac{1}{3}\end{aligned}[/tex]
Substitute the given slope and found value of b into the formula to create an equation for the line:
[tex]\boxed{y=-\dfrac{1}{3}x-\dfrac{1}{3}}[/tex]
Substitute the point (c, -2) into the equation and solve for c:
[tex]\begin{aligned} y&=-\dfrac{1}{3}x-\dfrac{1}{3}\\\implies -2&=-\dfrac{1}{3}c-\dfrac{1}{3}\\-2+\dfrac{1}{3}&=-\dfrac{1}{3}c-\dfrac{1}{3}+\dfrac{1}{3}\\-\dfrac{5}{3}&=-\dfrac{1}{3}c\\-\dfrac{5}{3} \cdot 3&=-\dfrac{1}{3}c \cdot 3\\-5&=-c\\\implies c & = 5\end{aligned}[/tex]
Solution
Therefore, the value of c is 5.
