Answer:
Surface area of square pyramid = 380 m²
Step-by-step explanation:
Given:
Side of square base =10 m
Height of Square pyramid = 14 m
Find:
Surface area of square pyramid
Computation:
Surface area of square pyramid = Surface area of Base + 4[Surface area of triangle]
Surface area of square pyramid = [side x side] + 4[(1/2)(b)(h)]
Surface area of square pyramid = [10 x 10] + 4[(1/2)(10)(14)]
Surface area of square pyramid = 100 + 4[70]
Surface area of square pyramid = 100 + 280
Surface area of square pyramid = 380 m²
Cuál es la fuerza total que ejerce 3 personas empujando una carreta? F1 = 30 N, F2 = 45 N, F3 = 38 N?
Respuesta:
113 N
Explicación paso a paso:
Las fuerzas ejercidas se dan como:
F1 = 30 N
F2 = 45 N
F3 = 38 N
A partir de los valores de las fuerzas ejercidas, podemos observar que todas las fuerzas están en la misma dirección; Dado que la fuerza total ejercida es un sol de las 3 fuerzas:
F1 + F2 + F3
(30N + 45N + 38N) = 113 N

Solve the equation. 36^6x-1 = 6^5x
The solution of the equation 36⁶x - 1 = 6⁵x is x = 1/2176774560.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
We have the equation:
36⁶x - 1 = 6⁵x
Simplifying,
(6²)⁶x - 1 = 6⁵x
6¹²x - 6⁵x = 1
2176782336x - 7776x = 1
x = 1/2176774560
The above equation is the required solution.
Therefore, the required value is x = 1/2176774560.

cos(0)=2/2 ,and <0<2pi, evaluate sin(0) and tan(0). sin (0)=? tan(0)=?
PLEASE HELP!!!!
Answer:
Step-by-step explanation:
The angle is between 3pi/2 and 2pi so it is in the fourth quadrant where both sin and tan are negative.
Given cos(θ) = sqrt(2)/2
cos^2(θ) + sin^2(θ) = 1
sine^2(θ) = 1 - 2/2^2 = 1 - 1/2 = 1/2
sin(θ) = +/1 sqrt(2)/2
As we know sin(θ) is negative,
sin(θ) = -sqrt(2)/2; the second answer
tan(θ) = sin(θ)/cos(θ) = -1
Answer:
Step-by-step explanation:
using (cosθ)^2 + (sinθ)^2 = 1
2/4 + (sinθ)^2 = 1
sinθ = [tex]\sqrt{2}/2[/tex]
or -[tex]\sqrt{2} /2[/tex]
By C-A-S-T, sinθ is -ve
sinθ = -[tex]\sqrt{2}/2[/tex]
tanθ = sinθ/cosθ = -1

co-terminal angle for -960... can you tell me? :D w/o looking at my answer below?
Your answer for co-terminal angle is ______________ :)
960 - 360 = 600
600 - 360 = 240
this is telling us that going in a clock wise direction.. as the -960 is, that the co-terminal angle is 240, which seems about right.. looking at the graph. so now. let's take 240 away from 360 to find that co-terminal angle but going in the positive direction or the counter clock wise direction
360-240 = 120
and yes.. that does look like 120 ° going in the positive direction.
now do you know the sec identity to use sin and cos???
look at the below diagram
sin sec
cos csc
tan cot
the trig function line up like that for a reason
sin 1/sin
cos 1/cos
sin/cos cos/sin
I put them in their sin and cos identities.. see.. they all line up that way
sec = 1/sin
csc = 1/cos
tan = sin/cos
cot = cos/sin
now... find
sec(120) = 1/sin(120)
do you know how to find sin(120) ?????
put it back to it's co-terminal angle in the 1st quadrat... I hope you know how to do this.. i'll just speed along... assuming you do
sin(120) = sin(60)= √3/2
so sec(120) = 1 / √3/2
so sec(120) = 2/ √3
10)
csc(315) = 1/cos(315)
find the co-terminal angle that you know in the 1st quadrant again...
so 315 = 45 in the 1st quadrant.. I just looked and can see that
so
csc(315) = 1/cos(315 = 1/cos(45) and cos(45) = √2/2
so then 1 / √2/2 = 2 / √2
csc(315) = 2 / √2
what i'm really wondering about.. is .. where is question 9)

The scatter plot shows the relationship between summer and winter temperatures. What is the range of the cluster shown in the
scatter plot?
A)
51°F to 71°F average January high temperature
B)
58°F to 61°F average January high temperature
C)
91°F to 98°F average July high temperature
D)
94°F to 95°F average July high temperature
Answer:
D
Step-by-step explanation:
Since it's talking abtou clusters, the only "cluster" like part there is there is where 94 and 95 are, so it has to be D.
Using the scatter plot and the range concept, it is found that the correct option is:
C) 91°F to 98°F average July high temperature
The range of a data-set is the set that contains all possible output values.
In this problem, the average July temperature is the output, plotted as function of the average January temperature, which is the input.
It varies from 91ºF to 98ºF, hence, the correct option is:C) 91°F to 98°F average July high temperature

Work out the size of an exterior and an interior angle of a regular 16-sided
polygon.
Answer:
exterior angle: 22.5°, interior angle: 157.5°
Step-by-step explanation:
the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides
=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°
the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]
=> [tex]\frac{360}{16}[/tex] = 22.5°

For her science project, jada wants to build a rectangular prism out of foam block. The block should have a volume of 350 in.³ and a height of 5 inches. Part A What tool can help Jada find possible dimensions for the base of the block Explain. Part B Give one pair of possible whole number dimensions for the base
Answer:
10 in * 7in
Step-by-step explanation:
Given that :
Volume of block = 350 in³
Height of block = 5 inches
The dimension of block can be expressed cubic units
Volume of a rectangular prism :
V = length * width * height
Let ; length * width = B
350 = B * 5
B = 350 / 5
B = 70 in²
Possible dimension of B:
B = length *width
70 in² = 10 in * 7in
Hence, possible whole number dimension for the base = 10 in * 7in

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)

Rewrite 8*8*8*8 using an exponent
Answer:
8⁴
Step-by-step explanation:
8*8*8*8 =8⁴
8 exponent 4
Answer:
[tex]8^{4}\\[/tex]
Step-by-step explanation:
An exponent describes how many times the base is repeatedly shown. For instance:
6³
6 is the base and 3 is the exponent. Because the exponent is 3, the base is repeated that many times. Here's what I mean:
6² = 6 (6) (6)
So in 8 (8) (8) (8), the base would be 8 and this is repeated 4 times. So the exponent would be 4.
So your answer would look like [tex]8^{4}[/tex].
