At your school, the building is 20 feet tall, a tree's height is 252 inches, and the flagpole is 6 yards high. Which of the thre

e objects casts the longest shadow?

First, all the heights have to be converted to similar units, say feet.

Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet

The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).

I NEED HELP...finding the slope-intercept form equation
Simora [160]

Answer: y=-13/12x-7

Step-by-step explanation:

To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }. We use the two given points to find the slope.

m=\frac{32-6}{-36-(-12)} =\frac{26}{-24} =-\frac{13}{12}

Now that we have our slope, we can start filling out the slope-intercept form equation.

y=mx+b

y=-13/12x+b

Since we don't know the y-intercept, we can use one of the given points and solve for b.

6=(-13/12)(-12)+b                              [multiply (-13/12) and -12]

6=13+b                                              [subtract both sides by 13]

b=-7

With the y-intercept, we can complete our equation.

y=-13/12x-7

In a group of 30 people, 9 people study French and 14 people study Spanish. Seven people study both French and Spanish.
Shtirlitz [24]
Or means not both
if  people study both then the number of people studying either french or spanish is 7 less than the total number of peple studig french and spanish because thoe 7 are common to both groups

9+14=total=23
23-7=16 people studing either

proabblity=desiredoutcmes/totalpossibe
desired=16
total=30
so 16/30=8/15 is the probablity

Write a quartic trinomial with a leading coefficient of 2 using standard form
lions [1.4K]
Quartic => polynolial degree 4, i.e. the highest exponent of the variable is 4

trinomial=> three terms

leading coefficient = the coefficient in front of the term with the highest exponent.

standard form=> ax^4 + bx^3 + c^2 + dx + e

Solution:

2x^4 + x^3 + 0x^2 + 0x + 30

which is equal to 2x^4 + x^3 + 30: this is a quartic trinomial with leading coefficient 2, written in standard form.
