Answer:
1.
x=-10
x=-6
2.
x=10
x=-3
Step-by-step explanation:
to find the zeros of a function you need to set it equal to zero:
x^2+16x+60=0
then you factor
(x+10)(x+6)=0
then you have to finish factoring/simplifying
x+10=0
-10
x=-10
x+6=0
-6
x=-6
and the same thing for number 2
x^2-7x-30=0
(x-10)(x-3)=0
x=10, x=3
Answer:
1.) x = -10, x = - 6
2.) x = 10, x = -3
Step-by-step explanation:
1.) factorize and set the equation to zero by multiplying a and c and finding factors of it that will result in b once added/subtracted
[tex]x^2+16x+60\\(x+10)(x+6)\\(x+10)(x+6)=0\\x=-10, x=-6[/tex]
2.) do the same for number 2:

Jessica and her best friend found some money under the couch. they split the money evenly, each getting $16.32. how much money did they find?
Based on the fact that Jessica and her best friend split the money and were able to get $16.32, the total amount that they found was $32.64
How much did Jessica and her friend find?The fact that they split the money evenly means that they split it in half which each person getting the same amount.
This means that the total amount they found was twice the amount that Jessica and her best friend got.
The total amount found is therefore:
= Jessica's share + Best friend's share
= 16.32 + 16.32
= $32.64

Kawan buys some protein bars at $0.90 each and bottled water at $0.70 each for a group hike. He buys twice as many bottles of water as protein bars. If he spends $46 in total, how many bottles of water and protein bars does he buy? Let x= the number of protein bars
Answer:
he buts 20 protein bars and 40 water bottles
Step-by-step explanation:
so first u set up an equation like this
46=.90x+.70(2x)
next you multipy
46=.90x+1.4x
Then add
46=2.3x
then divide by 2.3 to solve for x
x=20 so u have 20 protein bars
and 20 times 2 to find the amount of water bottles
Answer:
20 Protein bars and 40 waters.
Step-by-step explanation:
Let x = protein bars and y = waters
y = 2x .9x + .7 y = 46
Looking at the second equation, I would rather not work with decimals, so I will multiple the whole equation through by ten. That now gives m
9x + 7y = 460 Substitute in 2x for y (from my first equation above)
9x + 7(2x) = 460
9x +14x = 460 Combine 9x and 14x
23x = 460 Divide both sides by 23
x = 20 This is the number of protein bars. To find y plug 20 into the first equation above.
y = 2x
y =20(2)
y = 40
Write an expression, of the type A log(x B), for the transformed logarithmic function shown below:
The equation of the logarithmic function is y = log(x - 1)
How to write the equation of the transformed function?The points are given as:
(0,3) and (2,0)
The equation is represented as:
y = A log(x + B)
Substitute (2,0) in y = A log(x + B)
y = A log(x + B)
This means that:
0 = A log(2 + B)
This means that:
A = 0 or log(2 + B) = 0
Take the antilog of both sides of log(2 + B) = 0
2 + B = 1
Solve for B in 2 + B = 1
B = -1
Substitute B = -1 in y = A log(x + B)
y = A log(x - 1)
Substitute (0,3) in y = A log(x - 1)
3 = A log(0 - 1)
So, we have:
3 = A log(-1)
The above equation is undefined.
Hence, the equation of the logarithmic function is y = log(x - 1)

To support a tree damaged in a storm, a 12-foot wire is secured from the ground to the tree at a point 10 feet off the ground. The tree meets the ground at a right angle.
At approximately what angle does the wire meet the ground?
33.6°
39.8°
50.2°
56.4°
Using relations in a right triangle, it is found that the tree meets the wire at an angle of 56.4º.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, we have that:
The opposite side to the angle is of 10 feet.The hypotenuse is of 12 feet.Hence:
[tex]\sin{\alpha} = \frac{10}{12}[/tex]

What is Poisson's distribution formula?In order to comprehend separate events that happen at a steady pace over the course of a specified amount of time, Poisson's distributions are frequently utilized.
Formula for Poisson's distribution:
f(x) = ((λ^x)/x!).(e^(-λ))
x = Event to be calculated for
λ = Expected number of occurrences
P(X = x) = ((λ^x)/x!).(e^(-λ))
Here λ = 3 and x = 4
P(X = 4) = (81 / 4!).(e^(-3))
P(X = 4) = (81 * e^(-3))/24
P(X = 4) = (81 * 0.049)/24

From the top of a 16 m tall building, the angle of depression to a car on the road is 35°. To the nearest metre, how far is the car from the base of the building?
The distance of the car from the tall building to the nearest meter is 23m.
How far is the car from the base of the building?Given the data in the question;
Angle of depression θ = 35°Height of building = 16mDistance of car from building = xWe use trigonometric ratio since the scenario forms a right angle triangle.
tanθ = opposite / adjacent
tanθ = opposite / adjacent

Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.
A statistical term used to describe events that cannot occur concurrently is "mutually exclusive."
