Answer:
x = 2.
Step-by-step explanation:
First convert to vertex form:
f(x) = 5x^2 - 20x + 3
= 5(x^2 - 4x) + 3
= 5 [(x - 2)^2 - 4] + 3
= 5(x - 2)^2 -20 + 3
= 5(x - 2)^2 - 17.
The line of symmetry is x = 2.

write a similarity statement for the following pairs of triangle. Please answer sensibly
Answer:
this is your answer of your question.
Similarity statement for the pairs of triangles are
Triangle CJA ~ triangle EBA
Triangle RYT ~ triangle RME
Triangle TOL ~ triangle DAL
Triangle OEW ~ triangle OET ~ triangle TOW
What is similarity statement?A similarity statement is a statement that indicates that two or more geometric figures are similar to each other. It expresses the relationship between corresponding angles and corresponding sides of the figures.
The corresponding sides are
Triangle CJA ~ triangle EBA: AJ / AR = AC/AE
Triangle OEW ~ triangle OET ~ triangle TOW: OE/EW = ET/OE = OT / OW

Ali and Omar cycle around a cycle track.
Ali cycles each lap in 50 seconds.
Omar cycles each lap in 80 seconds.
Ali and Omar start cycling at the same time at the start line.
Work out how many laps they will each have cycled when they are next at the start line together
Answer and step-by-step explanation:
First, we will have to know at what time they will cross the line at the same time. So we can do the equation:
50 * 80 = 400
That means in 400 seconds they will be level again. Now, let's find Ali's amount of laps for 400 seconds, if it takes Ali 50 seconds for one lap. We can do:
400/50 = 8
This means it will take Ali 8 seconds to be leveled with Omar. Now Omar has the equation:
400/80 = 5
Because it takes him 80 seconds to take one lap. Therefore, it will take Ali 8 laps, and Omar 5 laps to be at the same starting line. Hope this helps!
Create an equation that models the total number of calories Jonathan consumes,y,based on number of biscuits he eats,x,and the 6 packages of pemmican
An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're specified that:
x = number of buiscuits Jonathan eastsy = number of calories Jonathan consumes6 = number of packages of pemmican that jonathan consumes.Let we take:
m = number of calories per buiscuit that Jonathan eats.
Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.
Let k = number of calories per package of pemmican, then:
for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.
Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.
or, we get:
[tex]y = mx + 6k[/tex]
Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

Suppose you deposit 1000 in account paying 3% annual interest compounded continuously use a equals PERT to find a balance after 10 years
Answer:
$1349
Step-by-step explanation:
Given data
Principal= $1000
Rate= 3%
Time= 10years
Applying the formula
A=Pe^rt
where e is the mathematical constant approximated as 2.7183
substitute
A=1000*2.7183^0.03*10
A=1000*2.7183^0.3
A=1000*1.349
A=1349
Hence the final amount after 10 years is
$1349

Find the 2nd of three consecutive positive even integers such that the product o the second and third integers is twenty more than ten times the first integer.
Answer:
10
Step-by-step explanation:
Let the three consecutive positive even integers be x-1, x and x+1
First = x-1
Second = x
Third = x+1
If the product of the second and third integers is twenty more than ten times the first integer, then;
x(x+1) = 20 + 10(x-1)
Open the bracket
x² + x = 20 + 10x - 10
x² + x = 10x + 10
x² + x - 10x - 10 = 0
x² - 9x - 10 = 0
x² -10x + x - 10 = 0
x(x-10)+ 1(x-10) = 0
(x+1)(x-10) = 0
x+1 = 0 and x-10 = 0
x = -1 and 10
Hence the 2nd of three consecutive positive even integers is 10

Step-by-step explanation:
Answer:
D is the correct graph.
Step-by-step explanation:
First you put the entries in ascending order, because that's how the line plot needs to be ordered.
1/4, 3/8, 1/2, 3/4, 7/8, 1, 1 1/4
So right there, you can rule out A.
You can rule out C because 1/4 does not occur 5 times in the data set.
B is incorrect because 3/8 isn't on the line plot at all.

-1 and -3 are not included because they are exactly on 0 on the y-axis and the question is asking for numbers that are LESS than 0.
