if cos ø = -4/7 what are the values of sin ø and tan ø
Answer:
tan=5,5
sin=0,98
Sry when Its wrong
Answer:
sin• = √13/7
tan•= -√13/4
Step-by-step explanation:
sin2•+ cos2• = 1
sin• = √1-cos2•
sin•= √1-(-4/7)2
sin•= √1-16/49
sin•= √ 49-16/49
sin•= √ 13/ 49
sin•= √13/7
tan• = sin•\cos•
= √13/7/-4/7
= -√13/4
David has counters. Lisa has 5 more counters than David. Samia has 4 times as many counters as David. The total number of counters is . Write a formula for in terms of . Give your answer in its simplest form.
Answer:
if 'c' equals number of counters, the answer is 6c + 5
Step-by-step explanation:
david has 'c'
lisa has '5+c'
samia has '4c'
add all terms together: c + 5 + c + 4c = 6c + 5
The formula for the total number of counters in terms of x is T = 6x + 5
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:
Lisa = David + 5
Lisa = x + 5
Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:
Samia = 4 × David
Samia = 4x
Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:
T = David + Lisa + Samia
T = x + (x + 5) + 4x
T = 6x + 5
Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

Use the graph to write a linear function that relates y to x.
y=
Answer:
y= -3x+1
Step-by-step explanation:
y=mx+b
find m: (y2-y1)/(x2-x1)
pick any two points: (-1,4) and (0,1)
plug them in: (4-1)/(-1-0)= -3=m
b is the y intercept which is 1=b
plug these into the equation for a line y=mx+b
y=-3x+1
A line with a slope of -4 passes through the point (0, 0). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer: y = -4x
Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

4x + 9y = 24
X + y = 10
Help ASAP
Answer:
14
Step-by-step explanation:
Answer:
(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])
Step-by-step explanation:
4x + 9y = 24
x + y = 10 $\Rightarrow$ x = 10 - y
Substituting the value of x (second equation) into the first equation, we get:
4 * (10 - y) + 9y = 24
40 - 4y + 9y = 24
5y = -16
y = -16/5.
So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

Factorise
x^2+18x+80
Answer:
(x + 10)(x + 8)
Step-by-step explanation:
Given
x² + 18x + 80
Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form
The population of a city can be modeled by the expression p(1.06)^t where t represents the number of years since 1990 and p represents the population in 1990. which statement is correct?
A. the year growth rate of the population is 0.06%
B. the yearly growth rate of the population is 0.6%
C. the yearly growth rate of the population is 1.06%
D. the yearly growth rate of the population is 6%
please respond if you actually know the answer :)
Answer:
D
Step-by-step explanation:
.06 =6%
The expression p(1.06)^t represents D. the yearly growth rate of the population is 6%
What is the population growth rate?The country's yearly average rate of change in population size over a certain time period. It expresses the proportion, growth in population size, and the total population for that year.
Given, The population of a city can be modeled by the expression
[tex]p(1.06)^t[/tex] where t represents the number of years.
This describes the yearly growth rate of the population is 6%.
If in the previous year the population was 100 this year it'll be 106 and next year it'll be 106% of 106 which is 112.36.

A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property

a. Find the mean of the radio prices. Round to the nearest cent.
Answer: $275
Step-by-step explanation:
The mean of the radio price is $275 or 27500 cents
Given,
Price of used original radio for a 1955 Thunderbird:
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
We need to find the mean of these prices.
And round to nearest cent.
What is the mean of a set of values?The mean is the average of all the given sets of values.
Example:
1,2,3,4
Mean = (1+2+3+4) / 4 = 10/4 = 2.5
Find the sum
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)
Sum = 3850
Find the number of prices.
= 14 prices
Find the mean.
= 3850 / 14
= 275
The mean radio price is $275.
Converting into cents.
$1 = 100 cents
$275 = 27500 cents
