The histogram shows the heights in meters of trees in a certain section of a park. How many trees are less than 20 meters tall? A. 16, B. 9, C. 4, or D. 15

Answers

Answer:

The histogram shows the heights in meters of trees in a certain section of a park.  

How many trees are less than 20 meters tall?

Answer: From the given histogram, we clearly see:

There is 1 tree with height less than 8 meters

There are 1 + 2 = 3 trees with height less than 12 meters

There are 3 + 2 = 5 trees with height less than 16 meters

There are 5 + 4 =9 trees with height less than 20 meters.

Therefore, the correct option is B. 9

Complete Question

Consider the isosceles triangle. left side (2z+8)units, bottom of triangle (4z-10)units, right side of triangle (2z+8) units Part A Which expression represents the perimeter of the triangle? a.(4z+16) units b.(6z−2)units c.(8z−16) units d.(8z+6) units

Answer:

d. (8z + 6) units

Step-by-step explanation:

The formula for the Perimeter of a Triangle is :Side A + Side B + Side C

Hence,

(2z + 8)units + (4z - 10) units + (2z + 8)units

= (2z + 8 + 4z - 10 + 2z + 8)units

Collect like terms

= 2z + 4z + 2z + 8 - 10 + 8

= 8z + 6 units

The expression that represents the perimeter of the triangle is (8z +6) units

The value 5 is an upper bound for the zeros of the function shown below.
f(x)= x4 + x3 – 11.x2 – 9x + 18
A. True

B. False

Answers

Answer:

The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

Step-by-step explanation:

Given

[tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex]

We know the rational zeros theorem such as:

if [tex]x=c[/tex] is a zero of the function [tex]f(x)[/tex],

then [tex]f(c) = 0[/tex].

As the [tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex] is a polynomial of degree [tex]4[/tex], hence it can not have more than [tex]4[/tex] real zeros.

Let us put certain values in the function,

[tex]f(5) = 448[/tex], [tex]f(4) = 126[/tex], [tex]f(3) = 0[/tex], [tex]f(2) = -20[/tex],

[tex]f(1) = 0[/tex], [tex]f(0) = 18[/tex], [tex]f(-1) = 16[/tex], [tex]f(-2) = 0[/tex], [tex]f(-3) = 0[/tex]

From the above calculation results, we determined that [tex]4[/tex] zeros as

[tex]x = -3, -2, 1,[/tex] and [tex]3[/tex].

Hence, we can check that

[tex]f(x) = (x+3)(x+2)(x-1)(x-3)[/tex]

Observe that,

[tex]for x > 3[/tex], [tex]f(x)[/tex] increases rapidly, so there will be no zeros for [tex]x>3[/tex].

Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

When solving a system of two linear equations
algebraically, how can you tell if the system has exactly one
solution?

Answers

Answer:

When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution.

What are the steps to graphing y=-3x+1

Answers

Answer:

The equation is in the form of y = mx + b which make it really easy to graph.

m = the slope

b = the y-intercept

You can make the first point at the y-intercept.

Where x = 0 and y = 1, or plot the point ( 0, 1 ).

Next we use the slope to start plotting new points.

The slope is -3 which, in rise over run form, is [tex]\frac{-3}{1}[/tex]. Since -3 is negative we go down 3 units from the y-intercept and 1 to the right because it's positive. This makes a point at ( 1, -2 ). Then from that point go down 3 and 1 to the right again to get ( 2, -5 ).

We can continue using the slope to plot more points and then draw a continuous line through them to finish graphing the linear function.

If 30/t = 18/r, then t/r =

30/t = 18/r

30r = 18t/r

Write a linear function f with f(4)=−3 and f(0)=−2.

Answers

Answer:

f(x)=-1/4x-2

Step-by-step explanation:

m=-3-(-2)/4-0=-1/4= slope

b=y-intercept=-2,

so f(x)=-1/4x-2

A linear function f with f(4)=−3 and f(0)=−2 is

[tex]f(x)=-\frac{1}{4}x-2[/tex]

Given :

a linear function f with f(4)=−3 and f(0)=−2.

f(0)=-2. It means y intercept is -2

Linear equation of a line is given by y=mx+b

where m is the slope and b is the y intercept

y intercept b is -2

Lets find out slope m . Lets use f(4)=-3  that is when x=4 the value of y is -3

[tex]y=mx+b\\y=mx-2\\x=4, y=-3\\-3=m(4)-2\\-3+2=4m\\-1=4m\\m=-\frac{1}{4}[/tex]

Now we replace in the equation of line y=mx+b

[tex]y=mx+b\\y=-\frac{1}{4}x-2[/tex]

Replace y with f(x) to get linear function

[tex]f(x)=-\frac{1}{4}x-2[/tex]

What is the angle of depression from the start of a 6-foot high access ramp that ends at a point 40 feet away along the ground? Nearest tenth of a degree.

Answers

Answer:

8.5 degrees

Step-by-step explanation:

The set up will give a right angles triangle;

Given

The height of the ramp (opposite) = 6 foot

distance away along the ground = 40 feet (adjacent)

Required

Angle of depression theta

Using the TOA identity;

tan theta = opposite/adjacent

tan theta = 6/40

tan theta = 0.15

theta = tan^-1{0.15}

theta =8.53 degrees

hence the angle of depression to nearest tenth of a degree is 89.5 degrees
