Evaluate: (8y+5) -2z; if y =3 and z =9
Answer:
11
Step-by-step explanation:
(8y + 5) - 2z
y = 3, z = 9
Let's plug in the given values.
(8(3) + 5) - 2(9)
First let's multiply.
(24 + 5) - 18
Now simplify within the parentheses.
29 - 18
Subtract.
11
This is your answer.

what percent of 500 is 255?
255 is what percent of 500? = 51.
The coordinate plane represents a map. Each grid unit represents 20 miles. A retail company has a warehouse at N(70, 40). A store is located at P(70, −20). How long will it take a truck driving at 50 miles per hour to drive from warehouse N to this store?
Answer:
24 hours
Step-by-step explanation:
Distance from warehouse (70, 40) to store (70, - 20)
x1 = 70 ; y1 = 40 ; x2 = 70 ; y2 = - 20
D = sqrt((x2-x1)² + (y2 - y1)²)
D = sqrt((70 - 70) + (-20 - 40)²)
D = sqrt(3600)
D = 60
Each unit grid represents 20 miles
The distance from store to ware house :
60 * 20 = 1200 miles
Speed of truck = 50 mph
Time taken = distance / speed
Time taken = 1200 / 50
Time taken = 24 hours

Which of the following is not an identity?
O A. sinx(cotx + tan x) = secx
O B. csc2x + sec2x = 1
O C. cos2x cscx-cscx = -sinx
D. cos2x - sin2x = 1- 2sin2x
Answer:
B..........................
The statement that is not an identity is cos(2x)csc(x) - csc(x) = -sin(x), the correct option is C.
What is the expansion of sum for cosine of sum of two angles?
Suppose we've got cosine of angle A and B measurements.
Then, we have:
sin(B)
[tex]\cos(A+B) = \cos(A)\cos(B) - \sin(A)\sin(B)[/tex]
If we get A = B, then:
[tex]\cos(2A) = \cos^2(A)- \sin^2(A)[/tex]
We are given that;
An identity is an equation that is true for all values of the variable.
The following three options are identities:
sin(x)(cot(x) + tan(x)) = sec(x)
csc^2(x) + sec^2(x) = 1
cos(2x) - sin(2x) = 1 - 2sin^2(x)
Therefore, by the trigonometric identities the answer will be cos(2x)csc(x) - csc(x) = -sin(x)

A cake recipe says to bake the cake until the center is 180°F. then let the cake cool to 100°F. The table shows temperature readings for the cake.
a. Given a room temperature of 69°F, what is an
exponential model for this data set?
b. How long does it take the cake to cool to the desired
temperature?
Answer:
8.058655822 mins
Step-by-step explanation:
We have a table and to solve for this we might want to find the equation for this
This is a exponential function
To solve for this we need the rate of decay and the x intercept
We know the x intercept is 180 because in 0 mins the temp is 180
To solve for decay we need to know the temp of the cake after 1 min
to get the decay value we can do
125= 180 (x)^5
.69444444444 = x^5
0.929667185 = x
so the equation would be
180 (0.929667185)^x
if we tell this equation to equal 100
we get
100 = 180 (0.929667185)^x
.5556 = (0.929667185)^x
log .5556 = log 0.929667185 *x
log .5556 / log .929667185)
8.058655822= x
After 8.058655822 mins the cake will be 100 degrees
You have 80 grams of a radioactive kind of europium. If its half-life is 9 years, how much will be left after 27 years?
9514 1404 393
Answer:
10 g
Step-by-step explanation:
27 years is 3 times the 9-year half-life. This means the quantity remaining has been cut in half 3 times:
((80×1/2)×1/2)×1/2 = 10 . . . . grams

Find x and y
Show all the work
Given:
A geometric figure.
To find:
The values of x and y.
Solution:
The given figure is a kite because it has two disjoint pairs of consecutive congruent sides.
Kite has one pair of congruent opposite angles. The angled included between non-congruent sides are congruent.
[tex](4x+13)^\circ=(5x-15)^\circ[/tex]
[tex]4x+13=5x-15[/tex]
[tex]13+15=5x-4x[/tex]
[tex]28=x[/tex]
The diagonal bisects the other pair of opposite angles.
The missing angle of the above triangle is [tex]y^\circ[/tex].
Using angle sum property, we get
[tex](y-9)^\circ+y^\circ+(4x+13)^\circ=180^\circ[/tex]
[tex](2y-9)^\circ+(4(28)+13)^\circ=180^\circ[/tex]
[tex](2y-9)^\circ+(125)^\circ=180^\circ[/tex]
[tex](2y-9)^\circ=180^\circ-125^\circ[/tex]
On further simplification, we get
[tex](2y-9)^\circ=55^\circ[/tex]
[tex]2y-9=55[/tex]
[tex]2y=55+9[/tex]
[tex]2y=64[/tex]
Divide both sides by 2.
[tex]y=32[/tex]
Therefore, the value of x is 28 and the value of y is 32.

If the expression has a positive value, which inequality represents all possible values of x in the expression? -2x+1 A. X < 1/2 B. X > 1/2 C. X < -1/2 D. X > -1/2
Answer:
x < 1/2
Step-by-step explanation:
For the inequality expression -2x + 1 to have a positive values, then it must be greater than zero as shown;
-2x+1 > 0
Subtract 1 from both sides
-2x+1-1 > 0 - 1
-2x > - 1
Divide both sides by -2
-2x/-2 < -1/-2
x < 1/2
Hence the required inequality solution is x < 1/2
