Given the definitions of f(x) and g(x) below, find the value of (fog)(-3).
f(x) = -4x + 7
g(x) = 2x2 + 5x – 8
Answer:
-93
Step-by-step explanation:
Step one:
given the expressions
[tex]f(x) = -4x + 7\\\\g(x) = 2x^2 + 5x- 8[/tex]
we want (fog)(-3).
but (fog) is
[tex]f(x) = -4x + 7\\\\\ (fog)=-4(2x^2 + 5x -8) + 7\\\\ (fog)=-8x^2-20x+32+7[/tex]
Step two:
fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7
[tex](fog)(-3)=-8x^2-20x+32+7\\\\ (fog)(-3)=-8(-3)^2-20(-3)+32+7\\\\ (fog)(-3)=-8*9+60+32+7\\\\ (fog)(-3)=-72-60+32+7\\\\ (fog)(-3)=-93[/tex]

Use the triangle shown on the right to answer the question. Which equation can you use to solve for a?
Answer:
B
Step-by-step explanation:
The equation that can be used to solve for 'a' is a/sin35° = 30/sin60°.
What is a triangle?A triangle is a three-sided closed-plane figure form by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know sine rule of triangles which states,
a/sinA + b/sinB + c/sinC.
We also know that the sum of all the interior angles in a triangle is 180°.
Therefore, The measure of angle B is 180° - (35 + 85)°.
= 60°.
So, The equation can you use to solve for 'a' would-be,
a/sin35° = 30/sin60°.
asin60° = 30sin35°.
(√3/2)a = 30×0.5735.
a = (30×0.5735)/0.866.
a = 17.205/0.866.
a = 19.87.

I also need help with this cuase honestly i'm really bad at math
Answer:
A
Step-by-step explanation:
Angles that form a straight line ( add up to 180 ) are supplementary
angles 1 and 2 / 3 and 4 / 5 and 6 /angles 7 and 8 are all supplementary
Angles 1 and 7 are congruent angles
so angle 2 = 125
Subtract 125 from 180 = 55
180 - 125 = 55 degrees

The sum of the measures of the angles of any triangle is 180. In a particular triangle, one angle is 40 greater than the smallest angle, and the third angle is 10 less than three times the smallest angle. Find the measure of the three angles.
Answer:
The smallest angle is 30 degrees, the second angle is 80 degrees and the third angle is 70 degrees
Step-by-step explanation:
let x = the smallest angle
This means that one angle is x+40, and the third angle is 3x-10. This make our equation:
x + 40 + 3x - 10 + x = 180
Combine like terms
5x + 30 = 180
Subtract 30 from both sides
5x = 150
Divide both sides by 5
x = 30
Plugging this in:
3x - 10 =
90 - 10 =
80
And for the other:
x + 40 =
30 + 40 =
70

Actually, there are two. They are the Parallelogram Opposite Sides Theorem and the Parallelogram Opposite Angles Theorem.
Step-by-step explanation:
POST means that if opposite sides of a quadrilateral are the same, it's a parallelogram.
POAT means that if opposite sides of a quadrilateral are the same, it's a parallelogram.

The distributive property to simplify the expression 7/6 (30 − 18) is (a) 14
Using the distributive property to simplify the expressionFrom the question, we have the following parameters that can be used in our computation:
7/6 (30 − 18)
When the expression is expanded, we have the following
7/6 (30 − 18) = 7/6 * 30 − 7/6 * 18
Evaluate the products
This gives

Jacob and Sarah are saving money to go on a trip. They need at least $1850 in order
to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $15
each time he mows a lawn and Sarah charges $10 each time she walks a dog. The
number of dog walks that Sarah has scheduled is no more than five times the
number of lawns Jacob has scheduled to mow. Sarah will walk at least 65 dogs.
Answer:
[tex]\textsf{Constraint 1}: \quad 15x+10y\geq 1850[/tex]
[tex]\textsf{Constraint 2}: \quad y \leq 5x[/tex]
[tex]\textsf{Constraint 3}: \quad y \geq 65[/tex]
Step-by-step explanation:
Inequality signs:
< Less than.≤ Less than or equal to.> More than.≥ More than or equal to.Given variables:
x = Number of lawns mowed.y = Number of dogs walked.Constraint 1Given information:
$15 = Charge for mowing a lawn.$10 = Charge for walking a dog.$1850 = Minimum amount needed for the trip.Therefore, the amount earned from mowing the lawns and walking dogs should be more than or equal to $1850:
[tex]\boxed{15x+10y\geq 1850}[/tex]
Constraint 2Given information:
The number of dog walks that Sarah has scheduled is no more than 5 times the number of lawns Jacob has scheduled to mow:Therefore, Sarah will walk less than or equal to 5 times the number of lawns mowed:
[tex]\boxed{y \leq 5x}[/tex]
Constraint 3Given information:
Sarah will walk at least 65 dogs.Therefore, Sarah will walk more than or equal to 65 dogs:

According to the solving the work done if the gorilla reaches that height:
= 8400 ft lb.
What is meant by "work done"?The work performed by a force is defined as the sum of the displacement and or the component of both the applied force of both the object in the displacement direction. Work is accomplished when we push a block with a certain amount of force, "F," which causes the body to move more quickly. W = F stands for "work done."
The purpose of the work?Anytime a force transports something over a distance, work is performed. By multiplying the force by both the distance moved inside this direction of the force, you may determine the amount of energy transferred or work accomplished.
According to the given data:The effort put in by a 350-pound gorilla climbing a 24 foot staircase can be computed as:
(a) t = 10 sec
WF = (350 lb) (24 ft)
= 8400 ft lb (answer)
(b) t = 5 sec
WF = (350 lb) (24 ft)
= 8400 ft lb
work done does not depends on time.
According to the solving the work done if the gorilla reaches that height:
= 8400 ft lb.

Answer: 307,000
Step-by-step explanation: Since 451 is less than 500, you want to round down.
Answer: 307,000
Step-by-step explanation: A number rounded to "the nearest thousand", must be multiple of 1000. In this case the value would be 306,000 or 307,000, or 308,000 or 309,000, depending on which of these our given number is closest (nearest) to. 307,495 is less than 307,500 , which is the value halfway between 307,000 and 308,000.
